Perovskites are a new class of semiconductor materials that are transforming what’s possible in solar energy. Unlike traditional silicon, perovskites can be tuned at the molecular level to absorb light more efficiently and capture a broader spectrum of the sun’s energy. They’re lightweight, versatile, and can be manufactured using simpler, lower-cost processes than today’s solar cells.

​

What makes them truly exciting is how they combine with silicon, the workhorse of the solar industry, to form perovskite-silicon tandem panels. This tandem approach unlocks record-setting efficiencies that generate more power from the same amount of sunlight, driving down the cost of clean energy while using less land and fewer resources.

​

Perovskites are also far more sustainable: they require only about 10% of the energy per watt to produce compared to silicon, and they avoid the use of rare earth metals or mining-intensive minerals. That means cleaner, faster, and more responsible solar at every step of the value chain.

Perovskites represent one of the most promising breakthroughs in renewable energy in decades, and Tandem PV is at the forefront of turning this science into durable, scalable technology that can power the world.
