SOLAR CELL

摘要

A solar cell is provided to increase the opposing length of a first drawing electrode and improve a flow of electrons by optimizing a ratio of an edge length of a light absorbing layer. A first electrode(11) and a second electrode(21) are disposed opposite to each other. A light absorbing layer(100) is formed on an upper surface of the first electrode. A plurality of drawing electrodes(17,27) are separated from the light absorbing layer. The drawing electrodes are formed along a first direction of the first electrode. A solar cell satisfies the following condition 1.3<=A/B<=125 where A is a length of a first edge and B is a length of a second edge.
