Improving Performance of Lead‐Free Formamidinium Tin Triiodide Perovskite Solar Cells by Tin Source Purification (Solar RRL 10∕2018)
Source abstract
Abstract
The purity of tin (Sn) sources is vital in terms of Sn-based perovskite solar cells’ fabrication. In article no. 1800136, Zhiwei Liu, Zuqiang Bian, and co-workers propose a simple purification method to reduce the detrimental Sn4+ existing in the precursor solutions by adding Sn powder. Aft er purification, the efficiency of FASnI3-based solar cells prepared from 99% SnI2 is elevated from 0.09% to a maximum value of 6.75% due to the improved morphology and lessened recombination loss.
