Abstract

PURPOSE:To enter light into a p-n junction efficiently and improve quantum efficiency by providing a means to introduce light entering from a direction intersecting a p-n junction face into a direction parallel to the p-n junction face. CONSTITUTION:Light entered from an incidence window 3 is reflected by a reflector 4, enters into an i layer from a direction parallel to an n layer and the i layer and flows a photoelectric current Ip. In order to enter light into the i layer efficiently, it is necessary to select materials which satisfy conditions that the light which propagates in the n layer is reflected by an upper electrode 1 and yet does not cause total reflection at the i layer. By so doing, light which propagates in the n layer enters the i layer sequentially resulting in the improvement of quantum efficiency and the increase of photoelectric current.
