Abstract:
We synthesized two highly volatile and low-cost solid additives, PT and TFT. The inclusion of PT and TFT effectively influences the aggregation behavior of D18: L8-BO during the film-forming process. Consequently, PT and TFT-treated D18: L8-BO-based OSCs achieved power conversion efficiencies of 18.28% and 19.19%, respectively. This study provides a straightforward approach for achieving efficient photovoltaic performance of OSCs.
