Taiwan-based c-Si solar cell start-up, Topcell Solar International, has successfully produced cells through its manufacturing lines and is now ramping production, according to the company. UMC, a rival foundry to TSMC, has a 60% majority stake in Topcell. The c-Si cell producer has a current capacity of 150MW, with plans to expand capacity by 450MW in the first quarter of 2011 and reach a capacity of at least 800MW in the third quarter. Topcell also has plans to reach 1GW by 2012, by which point the company expects to have employed over 2,000 workers.
Topcell Solar claims a product portfolio that includes 5 and 6 inch mono-crystalline and multi-crystalline solar cells designed by its own research and development team as well as collaborative projects with world-class institutions.
Minimum average conversion efficiencies for 6” multi-crystalline solar cell is said to be 16.4%. Topcell claims 17.8% for mono-crystalline solar cells.
