In this update to our June 2007 Newsletter we focus on developments in thin film PV. This is the fastest growing segment in PV as it shows promise to achieve parity with fossil fuel based energy production. First Solar has been on the forefront in this market segment demonstrating success in scaling up their CdTe technology to mass production. We also cover developments in CIGS, amorphous and microcrystalline Si, organic PV, and dye-sensitized cells are even being revived.
