ABSTRACT:
A solar cell having a by-pass diode includes a second conductivity type layer and a second conductivity type well formed on the front surface of a first conductivity type semiconductor substrate, and a first conductivity type layer formed in a second conductivity type well. A comb-shaped front electrode is formed over the front surface of the substrate and includes a plurality of narrow grid fingers and a bus portion to which the grid fingers are connected. At least a part of the bus portion of the electrode covers the entire first conductivity type layer. A back electrode is formed on the back surface of the substrate. The first conductivity type substrate and the second conductivity type layer constitute the solar cell, and the second conductivity type well and the first conductivity type layer constitute the by-pass diode. The solar cell and the by-pass diode are electrically connected in parallel between the front electrode and the back electrode with their polarities being opposite to each other.
