Abstract :
As a basic study of a fiber optic power transmission system, characteristics of a photovoltaic (PV) cell for high-intensity laser light were investigated. The energy conversion efficiency much higher than that for solar light was experimentally confirmed. As a degradation factor of the energy conversion efficiency of the PV cell, the effect of the heat caused by the laser was clarified. We showed that a heat radiator could effectively suppress the temperature increase and maintain the high conversion efficiency. We also clarified that the minute value of series resistance of the PV cell could degrade the PV cell characteristics.
