Efficiently using the sun's energy (docx)

Efficient use of solar energy to generate commercial and industrial power has long been a desired goal. Environmental concerns, government targets, and the increasing cost of traditional fuels has generated more research and potential product opportunities in recent years. Whilst a multitude of novel materials (such as CuIn1-xGaxSe2 and CdTe) are being researched and improved, silicon based materials still lead the industry because of their high efficiency and abundance of raw material.
