FRANKFURT, July 14 (Reuters) - Q-Cells SE (QCEG.DE: Quote, Profile, Research), the world's biggest maker of solar cells, withdrew its full-year sales outlook and said it saw no signs of an upturn in its market outlook, sending shares across the sector lower.

Along with peers in the once-booming industry, Q-Cells has been hit by a steep decline in prices for solar cells, mainly caused by an oversupply that built up during the boom years of 2007 and 2008.
