    Abstract There are instances in remote areas where heat is being wasted, e.g., in internal combustion, engines, etc. Some of this heat can be recovered to produce distilled water in solar stills. The solar still replaces the cooling tower, ponds, or radiators normally used to control the engine temperature. The diesel cooling water in such a system remains separate from the saline water in the solar still. The advantages of using such a system compared with a conventional solar still are: 1. (a) water costs are very much reduced 2. (b) the area occupied is much less, i.e., about 1 5 th 3. (c) production has much less seasonal variation 4. (d) the efficiency of the solar still is improved due to the higher operating temperatures. From experiments conducted at Highett using a Mk VI solar still fitted with a simple heat exchanger and a separate electrically-heated source of hot water to simulate the waste heat, design data are not available for application to working systems. The information required to match a solar still to a diesel's cooling requirement is: 1. (a) engine efficiency 2. (b) hourly fuel consumption 3. (c) hourly solar radiation 4. (d) hourly ambient temperatures. A by-product of this work has been the production of a “solar water heater” which costs less than that of the cheapest conventional system. This “solar” hot water system uses a heat exchanger similar to what is used to transfer the waste heat to the saline water. It is envisaged to have hot water productions approximately the same as the distilled water productions. The influence of hot water production on the output of the waste heat solar still is discussed.

    Abstract It is cost effective to manufacture a reflective surface of a solar parabolic trough concentrator in a parabolic cylinder shape by pure bending of a flat sheet. However, the surface manufactured by such an elastic bucking is only a coarse approximation of a parabola, which is not precise enough for meeting the demand of a high quality concentrator. A novel design concept was proposed to remove this error by applying an external force on both edge of a sheet, together with two additional forces: the edge torsion force and the pressing force. The optimal position and magnitude of two additional forces were figured out among various conditions, thereby a theoretically maximal concentration ratio up to 115 was found. Prototypes and engineering realizations of this method were also presented. This method provides a very attractive approach for low cost and high efficiency solar energy solutions.

    Abstract Simulations of divergent-chimney solar power plants (DSPPs) are conducted, and the DSPP performance studied by changing chimney outlet-to-inlet area ratios (COAR, representing the degree of divergence) over a wide range of values. Study method involves the use of total pressure potential (TPP) which consists of buoyancy and static pressure recovery in which an effective pressure potential recovery coefficient (EPPRC) is employed. Results show when the COAR is large enough, the boundary layer separation (BLS), flow stall and backflow will occur, vortex be formed, and a part of flow area be blocked. Due to the backflow from the ambient cool air, the temperature greatly decreases above the BLS point, possibly causing the reduction of buoyancy of the divergent chimney. With COAR increasing, the TPP initially increases and reaches a maximum for COAR = 8.7 then decreases. The mass flow rate and the power output have the same variational trend, while the collector temperature rise has the inverse variational trend. A maximum power of 231.7 kW is attained at COAR = 8.7, which is 11.9 times as high as that for COAR = 1. Before the occurrence of flow stall, the EPPRC decreases slowly due to the gently thickening of boundary layer and is higher than 0.91. While after the occurrence of flow stall, mainly due to the vortex and backflow the EPPRC greatly decreases and is found to decrease gradually with COAR. The effective ground heat flux increases the power output, but has little influence on the characteristics of the flow stall in the chimney, specifically the EPPRC.

    Abstract Together with the evolution of the daylight introduction into building facade systems, energy consumption assessment becomes more and more crucial to evaluate the synthetic performance. Traditional method for evaluating the shading effect was not sufficient to consider the dynamic lighting and energy performance of window configurations due to the varying sun position. In this paper, the field measurements combined with lighting and energy simulations were carried out to explore the optimization of window configurations and characteristics. The shading factors for complex configurations were inspected by field measurements conducted within a lighting sphere, as well as a scaled physical model. It resulted that the complex configurations provided higher energy performance and enough light transmission. Furthermore a new method which integrated the shading factor and solar heat gain coefficient was proposed to investigate the dynamic shading effect of different window configurations. The following energy analysis on a full size building was conducted in e-Quest for energy consumption evaluation. It predicted the considerable potential energy conservation for windows with dynamic solar heat gain coefficient, which encourages the architects to introduce the novel independent design proposal for windows.

    Abstract In this work, we examine the use of oil filled tubular optical concentrators coupled with a model organic bulk heterojunction photovoltaic: poly-3-hexathiophene-[6,6]-phenyl-C61-butyric-acid methyl-ester (P3HT:PCBM) to create a photovoltaic–photothermal hybrid solar collector. The organic photovoltaic cells were fabricated onto one half of a tubular light pipe and then silicone oil was flowed inside the pipe. This allows solar energy in the visible wavelengths to be effectively converted into electricity by photocell while simultaneously; the silicone oil captures the infrared radiation (IR) part of the spectrum as heat energy. The VIS–IR power conversion efficiency for this model organic system, under normally incident AM1.5G illumination was found to be: PCE ∼ 28%, which is combined by the photovoltaic efficiency (PCE ∼ 2%) and the photothermal efficiency (PCE ∼ 26%). We further show that the oil filled tube, acts as a passive optical element that concentrates the light onto the photovoltaic and thereby increases its overall efficiency but also the range of incident angles in which the light is efficiently captured.

    Abstract Atmospheric thermal assisted blade coating (TABC) method, which is quick film crystallization and easier fabrication than the commonly used spin-coating process, to prepare a high quality CH3NH3PbI3 perovskite film is investigated in this work. Selection of the perovskite precursor solvents and controlling the ratio of the mixed solvent as well as substrate temperature for perovskite film formation are important factors in this TABC process. Based on the results obtained in this work, substrate temperature is the key factor for managing the perovskite film phase transition which influences the film roughness and crystallinity. Furthermore, the high-quality perovskite films are prepared by perovskite precursors with mixture of solvents containing GBL/DMSO at the ratio from 1/9 to 5/5. By using the optimum substrate temperature of 130 °C and the GBL/DMSO solvent ratio of 1/9 (G01D09) for the preparation of small area n-i-p and p-i-n PSCs as well as the p-i-n type perovskite sub-module, the power conversion efficiencies of 17.55%, 16.90% and 13.03%, respectively, are acquired under the illumination of 100 mW/cm2 (AM 1.5G).

    Abstract The total internal quantum efficiency (IQE) of a flat-band p–n homojunction silicon solar cell and contributions of the three regions to it are numerically evaluated. It is found that both the spatial widths of the cell and the surface recombination velocities have significant impacts on the IQEs. By a linear transformation and a proper approximation, the differential equation of the minority carrier density in a textured cell becomes the same form as for the flat cell. What makes differences is that texturization slightly enhances the IQEs for photons with longer wavelengths while notably increasing external quantum efficiency. Hence it plays a good role for getting a better performance of a solar cell. It is considered that the results in the present are of universal technical importance both in designing solar cells and their surface structures.

    Abstract The defects of grain boundaries and film surface are harmful to the efficiency and stability of perovskite solar cells (PSCs). Defect passivation is an effective strategy to improve the performance of PSCs. In this work, a silane coupling agent 3-aminopropyltrimethoxysilane (APMS) was used as an additive of perovskite light-absorbing layer to passivate defects, thereby significantly improving charge transport, reducing charge recombination and improving device performance. The amino group in APMS can not only form a coordinate bond with the uncoordinated Pb in the perovskite, but also form a hydrogen bond with I (N-H⋯I). The crystallinity and uniformity of perovskite grains were improved obviously. Therefore, the addition of APMS greatly reduces the defects of perovskite and the power conversion efficiency (PCE) increased from 18.85% to 20.72% with less hysteresis. Furthermore, a proper carbon chain can be hydrophobic to improve the moisture stability of the perovskite. The PCE of the device remains 60% of the initial device after being placed at a humidity of 50–60% for 400 h. Therefore, this work proves that the use of silane coupling agents as additives is a promising strategy to achieve efficiency and stable PSCs.

    Abstract All-inorganic perovskites have attracted intense interest as light-absorbing materials, due to their large absorption coefficient, long charge carrier and diffusion length. However, it is a challenge to obtain the large-area synthesis of high-quality uniform perovskites layers. Here we demonstrate the applicability of the electrodeposition technique for the large-area fabricating of all-inorganic perovskite layers. PbO2 films were firstly electrodeposited on c-TiO2/m-TiO2/FTO substrate, which is then converted to PbI2 and CsPbI2−xBr1+x sequentially. By optimizing the preparation process, we have obtained a large area and high-quality CsPbI2−xBr1+x perovskite thin film, which exhibited strong UV–visible light absorption. Moreover, adding an appropriate amount of DMF solution to the CsBr-methanol solution can promote the reaction between CsBr and PbI2, could increase the grain size of the perovskite grain and could improve the density of the perovskite film. A power conversion efficiency of 6.87% is obtained for small cells (0.25 cm2) and 2.84% for large size cells (1.5 cm2) using the c-TiO2/m-TiO2/CsPbI2−xBr1+x/Carbon structure.

    Abstract In this paper, we physically modeled a bifacial perovskite/PERT-silicon tandem solar cells for the first time using Silvaco technology computer-aided design simulator (TCAD). The cell model was calibrated with the reported experimental data of perovskite solar cell (PSC) and PERT-silicon solar cell. The effects of perovskite thickness (tpvk) and perovskite bandgap were investigated on the performance of bifacial tandem solar cells under different albedo. The simulation results predict that the optimum tpvk increases with albedo intensities because a thicker perovskite layer is needed to facilitate current matching for high albedos. Moreover, the tpvk tolerance for a high-efficiency bifacial tandem solar cell increases with albedo. The simulation results reveal an efficiency over 31.9% for 0.45–1 μm of tpvk with 1.65–1.75 eV perovskite bandgap for a bifacial tandem cell under 30% albedo. Additionally, compared to the monofacial cell, the tandem design shows an enhancement of about 30% at the spectral albedo level of common grounds like concrete. The simulation and analysis presented in this work can help optimize perovskite/silicon tandem cell manufacturing to achieve higher power conversion efficiencies.
