Title:
PHOTOVOLTAIC ELEMENT
Document Type and Number:
Japanese Patent JP3442418
Kind Code:
B2
Abstract:
PURPOSE: To obtain a photovoltaic element having an excellent sensitivity to long wavelength light and an enhanced conversion efficiency.
CONSTITUTION: Within this photovoltaic element, several collector electrodes 4 in strips are formed on the surface of semiconductor on an underneath substrate 2 while the collector electrode 4 having tapered surface inclined to the generating layer 3 as it goes toward the incident region 6 between the collector electrodes 4 leads the incident beams by the tapered surface 4a to the generating layer part exposed in the region 6 so that long wavelength light may be reflected by the collector electrodes 4 and confined in the generating layer 3.
