Study on perovskite photovoltaic materials and photovoltaic performance of perovskite solar cells

Abstract

As a renewable energy, solar energy has aroused people’s attention and studies of this issue have become a hot topic throughout the world. How to turn solar energy into electric energy with a relatively better efficiency and lower costs has already become people’s new focus. Photovoltaic (PV) cell is such a new device that uses light to generate electricity. Among all of the PV products, the first-generation PV refers to silicon (Si) wafers with a power conversion efficiency (PCE) of 26%. However, these PV cells exhibit relatively high cost, limited conversion efficiency, and high processing cost. While, a new material called perovskite photovoltaic material came into people’s eyes. Perovskite materials exhibit variable structures, diversified composition and tubable performance. This material can help to improve the PCE into to a greater level, which is considered as the key performance of PV cells. This work introduces recent developments of halide perovskite and their performances as PV cells.
