Sanyo Solar Cell Efficiency Hits 22.3%

Sanyo has managed to achieve a solar cell efficiency of 22.3% with their latest proprietary solar cell known as “heterojunction with intrinsic thin layer (HIT) solar cell.” This was achieved during the research phase, so it remains to be seen whether practical application in the real world will translate to the same. Sanyo’s engineers are also focused on reducing the thickness of the HIT solar cell in due time. It actually good for efficiency, but what’s the cost? The thin-film solar industry is going towards “less efficient, but a lot cheaper.”
