Harry Atwater, a professor from Caltech and SPIE Member, says the way to make solar cells that can compete with fossil fuels is to make them thin and flexible. He is not the first to sing the praises of flexible solar cells, but people usually point to their potential applications on tents or backpacks, where they won't do much to reduce carbon emissions or fossil fuel use. Atwater likes them for their potential to reduce shipping and installation costs.
Atwater predicts that the cost of making and installing these solar cells can be less than a dollar a watt.
