Amino-acid-type alkylamine additive for high-performance wide-bandgap perovskite solar cells
A wide-bandgap (WBG) perovskite top component cell is vital for all perovskite-based tandem solar cells. However, such WBG perovskite solar cell (PSC) suffers from inferior crystallinity, huge voltage loss and poor photostability. Herein, we report a amino-acid-type alkylamine, 5-aminolevulinic acid hydrochloride (ALH) additive to address these issues to enhance the performance of WBG PSCs. It is found that the ALH effectively modulates the perovskite crystallization via chemical complexation between the ALH and PbI2, and enhances the crystallinity of the perovskite film. Moreover, the amino acid ALH not only passivates negatively charged deep-level IFA and IPb anti-site defects via –NH3+ terminals to reduce voltage loss, but also suppresses photo-induced phase segregation via the coordination between –COO− groups and halide vacancies. With these merits, the ALH-based PSC delivers an excellent power-conversion efficiency (PCE) of 21.13%, one of the highest values for inverted WBG PSCs. In addition, the air and thermal stability are also significantly improved. Our findings provide a feasible approach to prepare highly efficient and stable WBG PSCs.
期刊介绍：
The Chemical Engineering Journal is an international research journal that invites contributions of original and novel fundamental research. It aims to provide an international platform for presenting original fundamental research, interpretative reviews, and discussions on new developments in chemical engineering. The journal welcomes papers that describe novel theory and its practical application, as well as those that demonstrate the transfer of techniques from other disciplines. It also welcomes reports on carefully conducted experimental work that is soundly interpreted. The main focus of the journal is on original and rigorous research results that have broad significance. The Catalysis section within the Chemical Engineering Journal focuses specifically on Experimental and Theoretical studies in the fields of heterogeneous catalysis, molecular catalysis, and biocatalysis. These studies have industrial impact on various sectors such as chemicals, energy, materials, foods, healthcare, and environmental protection.
