Abstract
Apparatus including flexible line extending along a length. Flexible line includes first charge carrier-transporting body, photosensitive body over first charge carrier-transporting body, and second charge carrier-transporting body over photosensitive body. Each of first and second charge carrier-transporting bodies and photosensitive body extend along at least part of length of flexible line. Photosensitive body is capable of near-infrared or visible light-induced generation of charge carrier pairs. Second charge carrier-transporting body is at least semi-transparent to near-infrared light or visible light.
Claims20
An apparatus, comprising:
- a flexible line extending along a length, the flexible line including:
- a first charge carrier-transporting body extending along at least a part of the length of the flexible line;
- a photosensitive body over the first charge carrier-transporting body and extending along at least a part of the length of the flexible line, the photosensitive body capable of near-infrared light-induced or visible light-induced generation of charge carrier pairs;
- and
- a second charge carrier-transporting body over the photosensitive body and extending along at least a part of the length of the flexible line, the second charge carrier-transporting body being at least semi-transparent to near-infrared light or visible light.
A method, comprising:
- providing a flexible line extending along a length, the flexible line including a first charge carrier-transporting body, a photosensitive body over the first charge carrier-transporting body, and a second charge carrier-transporting body over the photosensitive body, each of the first and second charge carrier-transporting bodies and the photosensitive body extending along at least a part of the length of the flexible line, the photosensitive body being capable of near-infrared light-induced or visible light-induced generation of charge carrier pairs, and the second charge carrier-transporting body being at least semi-transparent to near-infrared light or visible light;
- forming an electrical circuit including the first and second charge carrier-transporting bodies and the photosensitive body, and a current detector;
- and
- detecting current generated by exposure of the flexible line to near-infrared light or visible light.
