Sanyo Electric Co Ltd achieved a conversion efficiency of 22.8% with its HIT (heterojunction with intrinsic thin layer) solar cell with a thickness of 98μm, which is about half as thick as existing HIT solar cells.Sanyo Electric realized the thinness while lowering conversion efficiency by only 0.2% (See related article). The company has not yet decided when it will start volume production of the cell.
"We can now reduce the amount of silicon used for HIT solar cells," the company said. "Silicon accounts for half the cost of those cells. So, we paved the way for lower-cost HIT solar cells."
Lower cost high efficiency solar sells are always good news.
