Abstract
A system includes a pixel including a diffusion layer in contact with an absorption layer. A transparent conductive oxide (TCO) is electrically connected to the diffusion layer. An overflow contact is in electrical communication with the TCO. The overflow contact can be spaced apart laterally from the diffusion layer. The pixel can be one of a plurality of similar pixels arranged in a grid pattern, wherein each pixel has a respective overflow contact, forming an overflow contact grid offset from the grid pattern.
