Sanyo Electric in the “Applied Physics 56th United speech-related” (March 30 ~ April 2, Tsukuba University) announced that on laptop battery , HIT (heterojunction with intrinsic thin layer) solar cell thickness of only 85μm, reduced to the original 1 / 2 of the following, and about 10cm square (103.3cm2) unit can still receive up to the conversion efficiency of 21.4%. The company in September 2008 held in Spain “23rd EU PVSEC” once released on similar results D5318 battery , D5540 battery , D5561 battery .
Help to achieve the reduction of thin silicon material costs. Products for mass production, if the high efficiency and low cost will enable both of, HIT can significantly improve the competitiveness of solar cells.
A new type HIT solar cell open circuit voltage higher to 739mV. Short-circuit current for 37.3mA/cm2, form factor (FF) was 0.776.
Sanyo Electric has developed a previous conversion efficiency of 22.3% for HIT solar cells FRU 08K8193 battery , FRU 08K8214 battery , FRU 92P1069 battery . However, the solar cell is about the thickness of 200μm. Although the thickness of the cut, but almost no lower conversion efficiency, open circuit voltage than the original 725mA/cm2 improved.
