Abstract

PURPOSE:To constitute the detector simply with low cost, by providing the unit stand which has the cylindrical sun ray limit body and the photodetector at the bottom. CONSTITUTION:The nonreflecting substance is coated inside the cylindrical solar ray limit body 9, and the solar cell 8 is provided at the bottom. Taking the incident angle of the solar rays A to the unit 5 as theta, the shade of the side wall of the cylinder 9 produced on the solar cell 8 is like the hatched line part B, and the area producing the current I0 is only the solar exposed part C. The current I0 produced at the area S for the solar exposed part C is I0=2KW[1.57r<2>-0.433(h.tantheta)<2>.r<2> sin<-1>(h.tantheta/2r)].costheta, where (r) is the radius of the sollar cell 8, (h) is the height to the top of the cylinder 9, W is the solar exposed electric power per unit area when the solar rays are rightly opposed to the unit stand 5, and K is the conversion factor of electric power and current.
