Abstract
Contemporarily, perovskite solar cells have become one of the hot topics among new energy. Currently, the highest photovoltaic conversion efficiency of perovskite tandem cells has reached 29.8%. Compared with silicon-based solar cells, which currently occupy most of the market share, they have a wider absorption band gap, and lower manufacturing cost and simpler manufacturing process, making them a strong candidate to replace silicon-based cells in the future. However, the commercialization of it is still hampered by its poor stability. This paper reviewed the state-of-art results from literatures, including the selection of materials for transport layers and the performance of different types, and summarize the limitations from the perspective of the working principle the cells. Finally, the current status of perovskite solar cells is summarized and the outlooks are put forward. These results offer suggestions for further studies focusing on perovskite solar cells.
