研究目的
Investigating the correlation between efficiency and device characterization in MAPbI3-xClx standard perovskite solar cells, focusing on the effects of annealing temperature of the ETL layer (SnO2) and various materials as an HTL layer.
研究成果
The annealing temperature of SnO2 at 220°C was found to be optimal for device performance, resulting in highly efficient carrier transportation with fewer defects at the interface. The use of PTAA as an HTL layer improved device efficiency, achieving a PCE of 13.3%. The study demonstrates the importance of optimizing both the ETL and HTL layers for enhancing perovskite solar cell performance.
研究不足
The study focuses on specific annealing temperatures and HTL materials, which may not cover all possible variations that could affect device performance. The hysteresis behavior observed in the devices suggests potential issues with interface properties and ion accumulation.
