Fast and Sensitive Solution-Processed Visible-Blind Perovskite UV Photodetectors

Fast and Sensitive Solution-Processed Visible-Blind Perovskite UV Photodetectors

The first visible‐blind UV photodetector based on MAPbCl3 integrated on a substrate exhibits excellent performance, with responsivities reaching 18 A W−1 below 400 nm and imaging‐compatible response times of 1 ms. This is achieved by using substrate‐integrated single crystals, thus overcoming the se...

Zusammenfassung:The first visible‐blind UV photodetector based on MAPbCl3 integrated on a substrate exhibits excellent performance, with responsivities reaching 18 A W−1 below 400 nm and imaging‐compatible response times of 1 ms. This is achieved by using substrate‐integrated single crystals, thus overcoming the severe limitations affecting thin films and offering a new application of efficient, solution‐processed, visible‐transparent perovskite optoelectronics.
