Lightly Concentrated PV (cont)

Following up on Monday's post, here's an excellent tutorial on PV provided by the US Dept of Energy. It discusses band gap, temperature effects, doping, etc. About 50% of sunlight that hits solar panels is outside the band gap and could perhaps be filtered by sheet films like these, though there are some off-axis issues with most filters.

In other news, Oriental Trading Company has 6" square mirror tiles for cheap. I'm still in.
