VCs Bet on Solar, Biofuel Money-Losers in Green Energy Frenzy

Using nanotechnology, the science of building microscopic materials from single atoms and molecules, Nanosolar's scientists created a "photovoltaic ink" that converts sunlight into electricity. The ink is coated onto flexible, foil-like strips that wind through roll presses similar to those that print newspapers. The thin film of ink, which is 1/100th the thickness of a silicon-based solar cell, can be attached to walls or any other flat surface or integrated into roofing material. Roscheisen says this process will enable Nanosolar to make solar cells for as little as a 10th of the cost of silicon panels. Nanosolar plans to build a factory in the Bay Area that can make enough solar cells to generate 120 megawatts of power by the end of 2007 and 430 megawatts by 2009.
