Testing of Perovskite Thin Film Solar Cells
Conference Year
2024
Abstract
This study investigates the impact of humidity on the performance and degradation of the perovskite thin film solar cells. Employing absorbance and reflectance optical-near infrared spectroscopy, we analyzed the characteristics of the absorber layer under standard humidity conditions of 85% relative humidity and 20 °C. Our findings reveal that both cells and thin films degrade in humid environments, with degradation rates exhibiting considerable variability based on the fabrication methods. Moreover, we have developed a database for solar testing data. This research underscores the importance of understanding the humidity-induced degradation in perovskite solar cells for advancing their long-term performance and reliability.
