ABSTRACT:
A photo-electric converting device has a plurality of emitters with a non-circular or non-dot shape in order to improve the photo-electric converting efficiency. The distance between the adjacent emitters has a predetermined relation to the average diffusion length of the minority carriers in a base layer in order to further improve the photo-electric conversion efficiency. The device is formed to have groove structures to restrain the photo-electric conversion loss due to reflected light.
