Abstract
(EN)
A photodetector (300) includes a first electrode (313) and a second electrode (314) on a base substrate (100); a light-sensitive layer (311) between the first electrode (313) and the second electrode (314); and a light-trapping layer (312) between the light-sensitive layer (311) and the base substrate (100), wherein a surface of the light-trapping layer (312) opposite from the base substrate (100) comprises a plurality of first recessed portions.
