Analysis of future prospects of perovskite-based solar cells

A revolutionary all-solid-state, hybrid solar cell based on organic-inorganic metal halide perovskite (CHjNH₃PbX₃) materials has piqued the interest of scientists all around the world, and is regarded as one of the top ten scientific accomplishments of 2013. Due to the advantages of its high extinction coefficient, high charge mobility, long carrier lifespan, and long carrier diffusion distance, perovskite materials can be employed not only as a light-absorbing layer, but also as an electron/hole transport layer. Perovskite solar cells‘ photoelectric power conversion efficiency has grown from 3.8 percent in 2009 to 22.1 percent in 2016, making them the greatest choice for a new generation of solar cells to replace existing silicon solar cells in the future. In this study, we outline the formation and process of perovskite solar cells, describe the distinct role of each layer, and concentrate on the enhancement of such layers’ function and its impact on cell performance. The perovskite light-absorbing layer's synthesis methods and performance properties are then reviewed. Finally, the obstacles and potential for perovskite solar cell development are briefly discussed.
