Multijunction Solar Cells Based on Hybrid Perovskites.

Abstract

We investigate the efficiency potential of organic-inorganic halide perovskite/c-Silicon tandem solar cells, a new class of photovoltaic devices. Tandem solar cells constructed from a crystalline Silicon bottom cell and a low-cost top cell offer a promising way to ensure long-term price reductions through high efficiency photovoltaic modules.

We are currently working on developing a bifacial thin-film top cell with an organic-inorganic semiconductor material having a bandgap greater than 1.6 eV. Methylammonium Lead trihalide has proved to be a promising material for the top cell. It can be solution-processed and allows for bandgap tuning by varying the halide concentration.

The bandgap of the top cell will be tuned such that it can be adapted in a tandem configuration along with a crystalline Silicon bottom cell. With the tandem configuration of perovskite/c-Si solar cells, we aim to cross the 25% power conversion efficiency barrier in order to deliver solutions for high-performance applications.
