Paper Abstract

The different types of state-of-the-art hybrid structures for photovoltaic focal plane arrays are subject to inherent fabrication problems. The island technology used for front-side illumination presents problems caused by the thinning and bonding of the photodetector material and by the forming of the connections. Devices for backside illumination are difficult to produce and very much dependent on the quality of the CdTe substrate. A new device which consists of a symmetrical front-and-back structure permits detection to take place on one face and electrical connection on the other. Its fabrication draws on classical HgCdTe array fabrication processes. This new symmetrical two-face structure yields diodes whose characteristics and manufacturing yields are entirely comparable to those obtained for conventional HgCdTe arrays.
