Abstract

We report two types of the tin-based solar cells, namely, lead-free tin perovskite solar cells (Sn-PVK-PV), tin lead alloyed perovskite solar cells (SnPb-PVK-PV). Tin oxide is well-known as the electron transport layer of solar cells such as Pb-PVK PV, dye-sensitized solar cells and organic solar cells. We found that SnOx works as the HTL of the Sn-PVK PV. The basic structure is as follows: FTO glass/SnOx/Sn-PVK/C60/BCP/Ag. Efficiency over 14% and the carrier dynamics are reported. All-perovskite tandem solar cells consisting of Pb-PVK-PV (top cell) and PbSn-PVK-PV (bottom cells) are reported. PbSn-PVK PV efficiency was improved by using hybrid SAM layers working as the HTL. The efficiency over 26% is reported.
