Key Points

The research aims to enhance the performance of inverted perovskite solar cells by suppressing self-aggregation in self-assembled monolayers using thiourea.
Used thiourea to treat self-assembled monolayers (SAMs)
Optimized the buried interface in solar cells
Analyzed the efficiency and stability of treated perovskite solar cells
Achieved a maximum power conversion efficiency (PCE) of 25.15%
Retained 91.2% PCE after 1200 hours of storage

Abstract

Thiourea suppresses SAM self-aggregation, optimizes buried interface and forms uniform films. The treated perovskite solar cells achieved a maximum PCE of 25.15% and retained 91.2% PCE after 1200 hours of storage.
