• Investigating hole transport in organic semiconductor layers of perovskite solar cells

Cheap and efficient solar cells are vital to reaching the UKs target of net zero emissions by 2050. In this area perovskite solar cells are a promising emerging technology, being considerably cheaper than the silicone based technology currently used while matching the efficiency. Perovskite solar cells are made of a sandwich of different materials, each layer with their own role. A key contributor to the efficiency of the cell is how fast one of these layers, made of an organic semiconductor, is able to move a type of charge called holes. The speed the holes move at is characterised by a property of the material called mobility, the higher the mobility the faster the holes move and the more efficient the solar cell is. This project aims to develop equipment that is able to measure the mobility of holes in organic semiconductors, contributing to the development of better solar cells.
