Abstract

Power generation characteristics of a Si PV cell under extremely high optical power near-infrared irradiation were investigated for use in optical wireless power transmission. We used high power LED light sources with 730 nm, 850 nm and 940 nm wavelengths and a condensing optics to realize 10-sun level extremely high optical power irradiation in the measurements. More than 0.22 W electrical power was generated from a 1 cm square Si heterojunction PV cell under about 1 W/cm²optical power irradiation. This is more than 10 times the power generation density of conventional Si solar panels. Estimated power conversion efficiencies under 10-sun power level near-infrared irradiation exceeded 22.5%, which indicate a potential for high-power wireless transmission with Si PV cells using near-infrared light.
