Recent progress on perovskite solar cells and our materials science

Abstract

Perovskite solar cells represent cost-effective next generation printable photovoltaics. In a relatively short period, power conversion efficiencies (PCEs) in such cells have been substantially increased, mainly due to improvements of the fabrication protocols for the perovskite layer as well as the development of new materials for buffer layers. In this presentation, the recent progress and perspective on this promising new type of photovoltaics are introduced, including our approaches toward development of high PCE cells in terms of materials science.
