覆晶堆疊太陽能電池之方法

A method of stacking flip-chip solar cell is provided, which makes use of flip-chip technique to grow a P-N junction semiconductor layer capable of absorbing light with long wave-length (such as infrared rays) for absorbing light with middle wave-length (such as visible light) and a P-N junction semiconductor layer capable of absorbing light with short wave-length (such as ultraviolet rays ). Accordingly, the invention uses flip-chip technique to stack solar cells, so as to solve the problem of lattice dis-match of each layer thereby enhancing efficiency of solar cell.
