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.
