| Kyocera achieves new record in solar cell efficiency Kyocera announced that it has achieved a new record of 18.5% energy conversion efficiency for a 15cm x 15cm multicrystalline silicon solar cell. Prior records for energy conversion efficiency in multicrystalline cells of this size were set by Kyocera, including 14.5% in 1989, 17.1% in 1996, and 17.7% in 2004. Kyocera's other efficiency benchmarks were achieved both by optimizing the cell's grid-line configuration and by texturing the cell's surface using the company's proprietary 'd.Blue' process, which maximizes sunlight collection by reducing reflectivity. The latest improvement is the result of increasing the amount of light intercepted by the cell by moving the front contacts to the back of the cell. Kyocera unveiled the new cell during the Renewable Energy 2006 International Exhibition held in Makuhari, Japan, from October 10 to October 13, 2006. write your comments about the article :: © 2006 Construction News :: home page |
