Tandem PV is a U.S-based company working on mechanically-stacked perovskite+silicon tandem solar panels. The Company started its way as Iris PV, which was later changed to Tandem PV.
Colin Bailie, the Company's CEO and a Stanford alum, joined forces with solar industry veteran Chris Eberspacher (former CTO at Hanwa and Applied Materials SunFab) and together, they have raised a few millions in grant funds and other support to get closer to their goal.
Tandem PV strived to achieve high-Efficiency PV for high-value applications. Tandem PV’s approach to manufacturing photovoltaic cells is to deposit a metal-halide perovskite solar cell, which is transparent to infrared light, over a silicon-based cell, which then absorbs that infrared energy.
