Based on what I know, which may not be accurate, that isn't quite true. Solar Ovonics has the highest efficiency units because they use a proprietary triple junction approach that gets a lot more electricity out of the light than all of the other solar products. In low light levels SO films are FAR superior to anything else out there. They are basically making electricity out of three wavelength ranges while all their competitors only use one range.

There are two big manufacturing differences between Solar Ovonics and NanoSolar.

1. Solar Ovonics uses a stainless steel substrate while NanoSolar uses Aluminum.

2. Solar Ovonics uses a sputtering type process to deposit material while NanoSolar CLAIMS they have found a way to do it using conventional ink deposition processes. If true then NanoSolar has a huge production advantage here.

Both are flexible. The Solar Ovonic product is much more efficient but the NanoSolar product may end up being much cheaper because they are using a cheaper substrate and can use standard ink deposition machinery.

It's going to be interesting to see what happens. There is a huge financial prize for whoever makes this practical and affordable. There is a massive market out there waiting for this.
