SOLAR CELL STRUCTURE HAVING TRANSPARENT PHOSPHOR LAYERS OF LONG PERSISTENCE AND PHOTOLUMINESCENCE IN FRONT

摘要

A solar cell structure having transparent long persistence phosphors and fluorescent material layers in front is provided to improve generation efficiency of a solar cell by using a light of blue type or a ultraviolet ray in generating power. A PN junction part is formed on a rear electrode. A transparent conductive film is formed on the PN junction part. A fluorescent material film and a long persistence phosphor film are formed on the transparent conductive film with integrated type or mixed type. A reflection barrier film on which a light of the solar cell is irradiated is formed on a top.
