SOLAR CELL AND METHOD FOR MANUFACTURING SAME

摘要

A solar cell includes: a substrate having heat dissipating characteristics; a solar cell bonded to the substrate such that the solar cell is electrically connected on a first conductive line and a second conductive line, which are disposed on a surface of the substrate; a lens, which is bonded to a transparent electrode of the solar cell; a plurality of projections, which maintain a gap between the substrate and the lens; tapered hole sections in the substrate, each of said tapered hole sections having a tapered section of each of the protruding sections fitted therein; and a sealing resin applied to the gap.
