ePoster: 

Poor CPSC (printed mesoscopic carbon based perovskite solar cell) PCE is often due to poor stack filling, resulting in low light absorption and poor TiO2 contact. There are many contributing factors to infiltration: any variable that prevents or slows precursor penetration of the mesoporous layers, as well as variables that impact the speed of crystallisation can have an impact. Consequently, determining the causes of poor infiltration is often difficult.

This work examines the factors that impact infiltration, with the aim of creating a reference resource of methods for targeted enhancement of performance and reprodcibility at device and module scale.
