3,5-Dinitrobenzoic Acid Enables Stable and Efficient HTL-Free MAPbI 3 Perovskite Solar Cells
Abstract
perovskite solar cells (CPSCs) have a power conversion efficiency (PCE) enhanced from 8.36 to 10.11%. Furthermore, after being kept for 22 days, the PCE of CPSCs treated with 1 mg-DNBZ can retain 87% of its initial PCE (under the condition of 30 °C and RH = 50 ± 5%), indicating a significant improvement in long-term durability. Our investigations reveal that the DNBZ additive strategy improves the stability, efficiency, performance, and quality of perovskite films. The present work provides a straightforward method to fabricate inexpensive and highly efficient CPSCs.
