Lead-Free Halide Perovskite Solar Cells with High Photocurrents Realized Through Vacancy Modulation
2014
Abstract
Lead free perovskite solar cells based on a CsSnI3 light absorber with a spectral response from 950 nm is demonstrated. The high photocurrents noted in the system are a consequence of SnF2 addition which reduces defect concentrations and hence the background charge carrier density.
