mammographic screening for breast cancer) with increased sensitivity at a substantially reduced cost. This will_x000D_
be achieved by replacing the semiconductor currently used in these devices (arsenic-doped amorphous_x000D_
selenium) with lead halide perovskites. This family of perovskite materials has had a transformative impact on_x000D_
solar energy research, owing to a unique combination of high absorption cross-section, high charge carrier_x000D_
mobility, and solution processability. We aim to have a similar impact on the field of X-ray image detectors._x000D_
Since these materials can be deposited using solution-based approaches that are both cost- and energy-efficient,_x000D_
as well as highly scalable, large reductions in manufacturing costs and energy inputs are expected._x000D_
Additionally, the high X-ray absorption cross-section of these lead-based materials should lead to_x000D_
improvements in detector sensitivity. The industrial partner (Analogic Canada) would like to develop_x000D_
perovskite photoconductors for X-ray image detectors, but lacks the technology and know-how to deposit_x000D_
relatively thick films of this material at scale. This project aims to fill that knowledge gap; we will develop_x000D_
