Abstract
A photosensor includes a base substrate; an insulating layer on the base substrate; and a photodiode including a semiconductor junction on a side of the insulating layer away from the base substrate. The semiconductor junction includes a first polarity semiconductor layer, an intrinsic semiconductor layer, and a second polarity semiconductor layer, stacked on the insulating layer. The second polarity semiconductor layer encapsulates a lateral surface of the intrinsic semiconductor layer.
