Estimating and controlling chromatic aberration losses for two-junction, two-terminal devices in refractive concentrator systems

Although previous studies have measured and calculated solar cell chromatic aberration losses and proposed methods for reducing these by modifying the optics, significant work remains to be done toward understanding how to quantify the losses and how various parameters affect this loss.

Summary:Although previous studies have measured and calculated solar cell chromatic aberration losses and proposed methods for reducing these by modifying the optics, significant work remains to be done toward understanding how to quantify the losses and how various parameters affect this loss. This paper presents an analytical definition and calculation method for chromatic aberration losses in Ga/sub 0.5/In/sub 0.5/P/GaAs solar cells. The effects of sheet resistance of the midlayers of the cell, total irradiance, incident spectrum, cell width and diode quality factor are studied. A method for measuring the midlayer resistance in finished solar cells is also described.
