The Recent Progress and the state-of-art applications of Perovskite Solar Cells

Abstract

With the awareness of using clean and sustainable energy, the utilization of solar power is of great importance in human society. Following the trend, solar cells are required to have higher and higher power conversion efficiency. Contemporarily, perovskite materials, as a new type of materials for construction of solar cells, exhibits great potential to have high efficiency. This article focuses on the methods on improving power conversion efficiencies of perovskite solar cells and discusses the limitation of recent technologies and industrial applications, and the future prospect of perovskite solar cells. To be specific, all the methods are focusing on the selection of materials suitable for cells design, from CsSnI3 to lead-based organic materials, the efficiencies have increased significantly. The method of stacking perovskite solar cells to make tandem solar cells improved efficiencies among all the methods. Meanwhile, the toxicity, low stability and difficulties in large-scale application are the main limitations for perovskite solar cells. For the future studies, it is important to search for materials with low toxicity and high stability. The technology for improving efficiency of large-scale solar cells is also required. These results provide a guideline for the future study in perovskite solar cells.
