Characteristics of the InGaP/InGaAs/Ge Triple-Junction Solar Cells with Concentration Photovoltaic System

Abstract:

The research on automatic tracking solar concentrator photovoltaic system research has become one of issues of solar PV technology. Aiming at the problem of cell performance degradation which caused by the non-uniform illumination in the concentrating photovoltaic system. A dish-style concentrating photovoltaic system with second stage concentrator was designed and built in this article. The author measured the performance of three junction GaInP/GaInAs/Ge solar cell. According to experiment result, the Pmm of solar cell was increased from 1.54 W/cm2 to 1.88 W/cm2. The η of solar cell was increased from 32% to 34.1% separately that compared with the concentrating photovoltaic system which without the second stage concentrator at the same concentration ratio(150X)
