Abstract

In various aspects, the present disclosure provides photodetector devices that may be provided in arrays. The photodetector includes a first electrode, a second electrode, and a photoactive layer assembly disposed therebetween. The photoactive layer assembly comprises a first charge transport layer, a second charge transport layer, and an amorphous silicon (a-Si) material substantially free of doping and being substantially free of doping disposed between the first charge transport layer and the second charge transport layer. The photodetector device transmits light in a predetermined range of wavelengths and is capable of generating detectable photocurrent when light having a light intensity of less than or equal to about 50 Lux is directed towards the photodetector device.
