The importance of the PV energy sector can be gauged by the presence of oil majors such as Shell and BP, whose solar cell production have reached 6% and 7% of the global market respectively in 2004.
The technology also could help invigorate the renewable-energy sector by providing efficient, lightning-fast storage for solar power, or, on a small scale, a flash-charge for cell phones and laptops.
