Off-the-shelf dyes improve solar cells

The Kids Science Zone -- Like most technologies, work on solar devices has proceeded in generational waves. First came bulk silicon-based solar cells built with techniques that borrowed heavily from those used to make computer chips. Next came work on thin films of materials specifically tailored to harvest the sun's energy, but still more or less borrowed from the realm of microelectronics manufacturing. Then came the third generation, described by one researcher and blogger as "the wild west," which among other objectives aims to build inexpensive next-generation solar cells by relying on decidedly low-tech wet chemistry.

It is going to be small increment after small increment. The real improvement is going to be in reducing cost and improving longevity in order to make the (current) long payback time more cost effective. (i.e. can we make the payback period shorter and.or extend the lifetime once the payback time is reached.)
