Terawatt Challenge for Thin-Film PV

The evolution of PV into one of the world's largest industries is not going to happen without major unforeseen problems. However, this study attempts to address the obvious ones, so that we can put aside the mythology of PV (for example, that it is only 'boutique power' or that one must pave the world with it to be useful) and get on with changing the world's energy infrastructure. With the yearsof rapid market growth now under way in PV, the author is sure this will not be the last effort to understand the real potential and pitfalls of meeting the Challenge.
