Abstract
We have studied photovoltaic characteristics of single-junction GaAs solar cells with/withoutan MgF2/ZnS anti-reflective coating (ARC) illuminated by low-density concentration (<10suns). By the ARC deposition, the short-circuit current density (JSC) and the fill factor (FF)are increased by 5 mA/cm2 and 5% at a standard illumination (1 sun), respectively, and theresulted conversion efficiency is enhanced by 45%. In contrast with the cell with no ARCshowing a rapid degradation with increasing concentration power, the efficiency ofARC-deposited cell remains almost constant as (17.7±0.3)% regardless of the concentration. It informs that ARC treatment is very effective in GaAs concentrator solar cells.
