Patent ID: 10096730

Abstract:
In various embodiments, an electronic device comprises, for example, at least one photosensitive layer and at least one carrier selective layer. Under one range of biases on the device, the photosensitive layer produces a photocurrent while illuminated. Under another range of biases on the device, the photosensitive does not produce a photocurrent while illuminated. A carrier selective layer expands the range of biases over which the photosensitive layer does not produce any photocurrent while illuminated. In various embodiments, an electronic device comprises, for example, at least one photosensitive layer and at least one carrier selective layer. Under a first range of biases on the device, the photosensitive layer is configured to collect a photocurrent while illuminated. Under a second range of biases on the device, the photosensitive layer is configured to collect at least M times lower photocurrent while illuminated compared to under the first range of biases.
