Perovskite Solar Cells: A Brief Introduction and some Remarks
El aumento espectacular y sin precedentes de las llamadas células solares de perovskita (PSC) en la eficiencia de conversión con procesos de fabricación de bajo costo ha llamado la atención de la comunidad científica en el campo de la energía fotovoltaica durante los últimos cuatro años. La inclusión de materiales absorbentes de tipo perovskita, típicamente CH 3 NH 3 PbI 3 , ha sido el factor clave para el desarrollo de esta tecnología emergente que ha creado muchas expectativas. Sin embargo, muchos aspectos poco conocidos de sus modos de operación aún necesitan explicaciones confiables. Este documento proporciona una breve introducción a la estructura, materiales y características de las PSC. Además, se proporcionan algunos comentarios sobre la estabilidad de estos dispositivos y se discute el estado del arte de varios temas de interés, como el fenómeno de histéresis de las curvas de corriente-voltaje.
L'augmentation spectaculaire et sans précédent de l'efficacité de conversion des cellules solaires dites pérovskites (CSP) avec des procédés de fabrication à faible coût a attiré l'attention de la communauté scientifique dans le domaine du photovoltaïque au cours des quatre dernières années. L'inclusion de matériaux absorbants de type pérovskite, typiquement CH 3 NH 3 PbI 3 , a été le facteur clé pour le développement de cette technologie émergente qui a créé beaucoup d'attentes. Cependant, de nombreux aspects mal compris de ses modes de fonctionnement ont encore besoin d'explications fiables. Cet article fournit une brève introduction à la structure, aux matériaux et aux caractéristiques des CSP. En outre, quelques remarques sur la stabilité de ces dispositifs sont fournies et l'état de l'art de plusieurs sujets d'intérêt est discuté, tels que le phénomène d'hystérésis des courbes courant-tension.
The spectacular and unprecedented rise of so-called perovskite solar cells (PSCs) in conversion efficiency with low-cost manufacturing processes has grabbed the attention of the scientific community in the field of photovoltaics during the last four years.The inclusion of perovskite type absorber materials, typically CH 3 NH 3 PbI 3 , has been the key factor for the development of this emerging technology that has created a lot of expectations.However, many poorly understood aspects of its operating modes still need of reliable explanations.This paper provides a brief introduction to the structure, materials and characteristics of PSCs.In addition, some remarks about the stability of these devices are provided and the state-of-the-art of several subjects of interest is discussed, such as the hysteresis phenomenon of current-voltage curves.
استحوذ الارتفاع المذهل وغير المسبوق لما يسمى بالخلايا الشمسية البيروفسكيتية (PSCs) في كفاءة التحويل مع عمليات التصنيع منخفضة التكلفة على اهتمام المجتمع العلمي في مجال الخلايا الكهروضوئية خلال السنوات الأربع الماضية. كان إدراج مواد امتصاص من نوع البيروفسكيت، عادةً CH 3 NH 3 PbI 3 ، هو العامل الرئيسي لتطوير هذه التكنولوجيا الناشئة التي خلقت الكثير من التوقعات. ومع ذلك، لا تزال العديد من الجوانب غير المفهومة لأوضاع تشغيلها بحاجة إلى تفسيرات موثوقة. توفر هذه الورقة مقدمة موجزة لهيكل ومواد وخصائص PSC. بالإضافة إلى ذلك، يتم تقديم بعض الملاحظات حول استقرار هذه الأجهزة ومناقشة أحدث ما توصلت إليه العديد من الموضوعات المثيرة للاهتمام، مثل ظاهرة التباطؤ في منحنيات الجهد الحالي.
