Abstract
A photosensitive device is provided. The photosensitive device includes a sensing stack, an anti-reflective layer, an optical filter, a first electrode, and a second electrode. The sensing stack includes a first semiconductor layer, an intrinsic semiconductor layer disposed on the first semiconductor layer, and a second semiconductor layer disposed on the intrinsic semiconductor layer. The anti-reflective layer is disposed on a side of the sensing stack. The optical filter is disposed on the anti-reflective layer and blocks input light with an incident angle greater than 50 degrees. The first electrode and the second electrode are disposed on the sensing stack.
