Abstract
We have succeeded in harvesting energy in the NIR region by using Sn halide based perovskite materials. The cell has the following composition: F-doped SnO2 layered glass/compact titania layer/porous titania layer/Sn based perovskite material/ p-type polymer semiconductor. The edge of the incident photon to current efficiency (IPCE) edge reached 1040 nm. 4.18 % efficiency with open circuit efficiency (Voc):0.42 V, fill factor (FF): 0.5, short circuit current (Jsc): 20.04 mA/cm2 is reported.
