PERFORMANCE IMPROVING METHOD AND PERFORMANCE RESTORING METHOD FOR OBJECT SOLAR CELL HAVING TITANIUM OXIDE FILM SUPPORTED BY PHOTOSENSITIZING DYE AND ELECTROLYTE IN STRUCTURE, AND SOLAR CELL SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a performance improving method and a performance restoring method for an object solar cell having a titanium oxide film supported by photosensitizing dye and electrolyte in a structure, for easily improving the performance and restoring the deteriorating performance at an installation site while reducing cost and labor, and to provide a solar cell system.;SOLUTION: Into each of the solar cell having the titanium oxide film supported by the dye and the electrolyte in the structure, its module and a photovoltaic power generation system including them, a forward current is carried (1) in a range of 0.1-2 mA/cm² per the light receiving area of a unit cell in initial performance improving processing, and (2) in a range of 0.2-3 mA/cm² in deterioration restoring processing.;COPYRIGHT: (C)2009,JPO&INPIT
