Abstract
Abstract A covered solar cell having improved light reception characteristic comprises a layer of a semiconductor material, an electrical contact, a transparent cover plate and a transparent film interposed between the cover plate and the layer of semiconductor material wherein the transparent film contains a block copolymer having at least two monoalkenyl arene polymer end blocks A and at least one polymer mid block B selected from the group consisting of substantially completely hydrogenated conjugated diene polymer blocks, ethylene-propylene polymer blocks and ethylenebutene polymer blocks. Also disclosed and claimed are novel methods for making the covered solar cell.
