Organolead halide perovskites: Synthetic routes, structural features, and their potential in the development of photovoltaic

Abstract

About 13 TW of energy is needed to sustain the lifestyle of people worldwide but an additional 10 TW clean energy will be required by 2050. The increase in the world population and the demand for energy that rely on fossil fuels has resulted in global warming that necessitates the need for alternative energy such as solar. Solar energy is abundant and readily available, and its use will contribute to sustainable development. Metal halide perovskites are promising materials for the development of next-generation solar cells. The power conversion efficiency (PCE) of 25.8% obtained for organolead halide perovskite is close to the polycrystalline solar cell’s efficiency at 26.3% and these materials offer great prospects for future photovoltaic development. To approach the theoretical efficiency limit, it is very important to study the development of perovskite solar cells in terms of material composition, fabrication techniques, and device architectures with emphasis on charge transport layers and electrodes. Limitations to PCE and stability of perovskites, optoelectronic properties, lifetime and stability, wide-scale applications, components of the perovskites solar cell, the standard for testing conditions for good stability and its evolution into the lower layered perovskite solar cells were examined in the current review.
