There are a couple of new perovskite solar cells breakthroughs this week which we think should be talking to one another. These solar cells are built around a perovskite structured compound, often with lead or tin halide as the light-harvesting active layer. This is the pioneering edge of solar, and perovskite is advancing rapidly with the promise of very low production costs. One of the issues with any “disruptive” technology is how will it get off the ground? The Crystalline Silicon solar process has not only had a lot of money spent perfecting and improving it, but it has made companies a lot of money. When you reinvest a percentage of revenues into the minutiae of process detail, and that…
