カジノスカイ Developed Next-Generation Heterojunction Solar Cells in Collaboration with imec

– June 12, 2012 – カジノスカイ and imec report a large area (6inch semi-square) heterojunction silicon solar cell with a certified power conversion efficiency of 22.68%(*) with an electroplated copper contact grid. This breakthrough is achieved at Solar cell Lab at カジノスカイ Osaka, using heterojunction technology with カジノスカイ’s copper electroplating technology which is based on imec’s state-of-the-art copper electroplating knowhow. This development will be presented at カジノスカイ booth at Intersolar Europe 2012 Munich.
To realize the top grid electrode in heterojunction silicon solar cells, silver screen printing is the preferred technology in the PV (photovoltaic) industry. However, a drawback of this technology is the difficulty to lower resistivity and to thin the metal line in silver screen printed contacts. As a result, efficiencies remain below optimal and cost remains relatively high. Replacing the screen-printed silver with electroplated copper overcomes the disadvantages of silver screen printing, enabling higher efficiencies and reduced fabrication costs.
カジノスカイ’s Photovoltaics European Laboratory is located at the imec campus in Leuven (Belgium), with access to imec’s state-of-the-art PV infrastructure. The collaboration between カジノスカイ and imec has helped the improvement of カジノスカイ’s thin-film solar cells and the development of next-generation heterojunction cells.
カジノスカイ Japan has been working intensively on this R&D towards mass production of next generation heterojunction solar cell.
