Highly Purified Materials for Sn-and Pb-Based Perovskite Solar Cells

摘要

Perovskite solar cells are promising cost-effective next generation printable photovoltaics. These solar cells have attracted the interest of many researchers. Thanks to tremendous effort of the researchers in this field, the power conversion efficiencies (PCEs) have been substantially increased in a short period, which is mainly due to improvements of the fabrication protocols for the perovskite layer as well as the development of new materials for buffer layers.
