Title: Surface configuration of amorphous silicon solar battery
Inventor: KUROGO HARUJI
IPC: H01L31/04
Filed: 1994-09-01
Abstract: PURPOSE: To increase a photosensitive area and to receive direct light and scattering light effectively by making a surface of an amorphous silicon solar battery a continuation of quandrangular pyramids while a surface of a conventional one is shaped plane. CONSTITUTION: A glass substrate is shaped into a quandrangular pyramid and a continuation of quandrangular pyramids, a transparent electrode 2 is formed in a glass substrate 1 of a quandrangular pyramid and a continuation of quandrangular pyramids and then a rear electrode 4 is formed by forming amorphous silicon 3 by gas reaction. Since a surface of an amorphous silicon solar battery is shaped into a quandrangular pyramid and a continuation of quandrangular pyramids, a photosensitive area to a bottom area increases and not only direct light but also scattering light from all directions and scattering light reflected by itself are effectively received.  Therefore, in the case of an equilateral quandrangular pyramid whose height is half a length of one side of a bottom of the quandrangular pyramid, a photosensitive area is 1.4 times a bottom area and direct light and scattering light can be effectively taken.
