Panel type solar radiation concentrating sensor for use with e.g. solar tracking device, has mirrors formed with plane reflective surfaces whose dimensions and shapes are chosen in correspondence to active surface

摘要

The sensor has a photovoltaic cell (2) and a partially reflecting surface formed of a reflector, where each photovoltaic cell includes has a polygonal active surface rotated toward a reflecting surface to receive solar radiation reflected by the reflector. The reflector includes three mirrors, where each mirror is formed with a plane reflective surface whose dimensions and shapes are chosen in correspondence with that of the active surface, so that the solar radiation reflected by the mirrors on the plane reflective surface covers the active surface.
