Did you know there are alternatives to standard silicon solar panels? Or that someday soon, you might be able install a solar panel that is 50 percent more efficient than the average silicon PV solar panel?

That’s exactly what Iris Photovoltaics Inc. (Iris PV) is aiming to produce. The Berkeley, California-based company is working to modernize how silicon solar panels are manufactured. In addition, they are attempting to increase the efficiency of PVs to a range of 25-30 percent.

The U.S. Department of Energy (DOE) Small Business Vouchers (SBV) program award recipient’s technology adds a crystalline metal-halide perovskite layer to
