SOLAR CELL

摘要

PURPOSE: A solar cell is provided to improve photonic efficiency by applying a buffer layer having new composition and reducing light loss in a waveband. CONSTITUTION: A first electrode(110) is arranged in a substrate. A light absorption layer(120) is located in the first electrode. A buffer layer(130) is arranged on the light absorption layer. A second electrode(140) is arranged on the buffer layer. A reflection barrier layer(150) and a grid electrode(160) are located the second electrode.
