Perovskites represent one of the most promising advances in solar energy in decades. These synthetic crystalline semiconductor materials can be precisely tuned at the molecular level, allowing them to absorb high-energy portions of the solar spectrum that traditional silicon leaves unused.

 

The active perovskite layer is extraordinarily thin, roughly 200 times thinner than a silicon cell and about one-hundredth the width of a human hair. Across an entire solar panel, it adds only a few grams of material while delivering a substantial increase in power.

 

What makes perovskites truly exciting is how they combine with silicon, the workhorse of the solar industry, to form perovskite-silicon tandem panels. This tandem approach allows each material to do what it does best, generating more power from the same sunlight while improving the economics of solar and reducing land and resource requirements.

 

Perovskites also deliver impact at an almost invisible level. Applied as an ultra-thin layer, they add very little material to a solar panel while unlocking a substantial increase in performance. This elegant tradeoff is what makes perovskite-silicon tandems such a powerful next step for solar at scale.

 

Tandem PV is focused on translating this scientific potential into durable, manufacturable technology designed for real-world deployment.
