The photovoltaic (PV) market is currently dominated by crystalline silicon solar cells (c-Si SC), with < 21 % power conversion efficiency (PCE), but widespread use of this technology is cost-limited. Alternatively, thin film solar cells (TFSC) can be manufactured cheaply but do not perform comparably and degrade more quickly than c-Si SC. Although recent advances in TFSC technology have been made using perovskite absorbing layers, a principle challenge in PV cell design is optimising charge collection and a significant breakthrough is required to achieve the theoretical maximum PCE. It has therefore been proposed that the unprecedented electronic and structural properties of graphene offer a unique opportunity for a step change improvement in TFSC efficiency and surface stability, through carefully engineered incorporation of graphene into TFSC. The project aims to prove the concept of graphene incorporation into thin film solid-state Dye Sensitised Solar Cells (ssDSC) based on perovskite, fully exploring the possible efficiency gains, as well as improvements to the surface properties of graphene encapsulated devices. The outcomes of a successful project can be developed to produce a step change in SC performance, providing higher PCE at lower cost than existing c-Si SC technologies, with reduced degradation.
