Renewable Solar Energy: Has the Sun Finally Risen on Photovoltaics?
The confluence of oil price spikes, heightened concerns about the environment and now the likelihood of new government driven economic stimuli has increased the discussion about renewable energy policy and investments around the globe. Increased global electricity demand continues to be driven by more electronics, the rise of emerging economies and soon, the electrification of transportation thereby putting even more emphasis on abundant and clean methods of generation. So called "solar panels" have been long proposed as a significant component of such a solution, dating back to the discovery of the photovoltaic (PV) effect in 1839, to the first silicon solar cell in 1954 and the first oil price spikes in the 1970s. But even with all the compelling factors, PV currently generates less than 0.1% of the world's electricity. After a review of the overall renewable energy landscape, including the central role of economics, we present here the case that PV is on the verge of becoming a major source of electrical power through a principle similar to that which underlies the 50 year progress of IC technology - the reduction of unit cost through nanomanufacturing.
