✦ Synopsis

Experimental results showing dependence of short-circuit current density J~ on the thickness of an antireflection (AR) film are given for two types of textured polycrystalline silicon solar cells. Results which identify changes in Jsc caused by encapsulation are also given for different AR film thicknesses. These results can be interpreted in terms of the changes in the optical coupling associated with the changes in the AR film thickness and as a result of encapsulation. Typical variations in optical reflectance and the spectral responses of the cell, as a result of changes in the AR film thickness, are presented to illustrate changes in the optical coupling.
