For all of its growth, today’s solar industry relies on legacy technologies with inherent limitations. Conventional solar modules convert sunlight to electricity using a single light-absorbing material and are nearing an efficiency threshold. Tandem technology layers two different light absorbers to increase energy harvest from more of the solar spectrum, boosting the power output of modules by 30%.
The technologies that enable the leap to tandem solar, the Direct Wafer process and durable perovskites, will create a solar future defined by high-efficiency and lower embedded energy and materials.
They will also underpin a massive industry to deliver clean electricity to meet our planets growing energy needs.
