This paper investigates enhancing perovskite solar cells' efficiency and stability using bi-TPAI surface modulation. It significantly improves power conversion efficiency and operational stability by passivating surface defects and facilitating charge extraction.

How Paios was used

Paios was employed for transient photocurrent and photovoltage measurements, revealing optimized charge dynamics and reduced recombination, which contribute to the observed performance improvements.
