Vertical 2D/3D Heterojunction of Tin Perovskites for Highly Efficient HTM-Free Perovskite Solar Cell
Source abstract
Abstract
Tin perovskite solar cells (PSCs) have been attracting attention in photovoltaic application, while the performance of Sn PSCs, especially for hole-transporting materials (HTMs)-free configuration, is relatively poor because of short mean-free-path for photogenerated charge carriers. We report a p–n junction with spatially appropriate architecture and energetic alignment in perovskite light-absorbing layer, resulting in an excellent performance of HTM-free Sn PSCs with a power conversion efficiency (PCE) of 5.17%, the highest value reported in HTM-free Sn PSCs. The p–n junction configuration plays a key role in achieving high efficiency and realizing excellent stability for more than 200 h operation.
