Lead-tin perovskite solar cells: exploring thermal evaporation and interface engineering for improved stability and performance

Thesis

This thesis explores the development of narrow-bandgap, lead-tin (PbSn), perovskite solar cells (PSCs), focusing on the enhancement of performance and stability through two fabrication techniques: solution processing and vacuum thermal evaporation. It also covers how to build, optimise, and upgrade customised evaporator design and how to optimise co-evaporation recipe of perovskites. It covers several key aspects of the fabrication process, device characterisation, and stability testing.
