Abstract

The stability of perovskite solar cells made of inorganic CsPbI₃ is impressive, but the power conversion efficiency still needs improvement due to high open circuit loss (V_loss). This issue is often attributed to a mismatch in energy levels between the inorganic perovskite layer and the charge-selective contacts at the interface. Therefore, it is essential to understand the interface dynamics in these solar cells. Despite significant efforts since 2015 to address CsPbI₃ crystallisation and phase stability at operational temperatures, a more comprehensive understanding of the interface is necessary to advance CsPbI₃-based devices. We focus on presenting a detailed surface chemistry and interfacial dynamics analysis using spectroscopic and optical techniques. In this talk, we will have a comprehensive discussion on the effects of the annealing environment on the intrinsic properties of the interface. Additionally, we will discuss the implementation of interface engineering using dipole molecules to mitigate V_loss to improve the efficiency of solar cell devices.
