Twophold is a clean‑energy startup working on materials that improve solar panel efficiency. In conventional solar cells, excess energy from high-energy light is lost as heat. TwoPhold captures this lost energy by splitting a single photon into two usable charges, generating more electricity from the same sunlight. This enables solar cells to move beyond the conventional ~32% efficiency limit and approach ~44%. 

Twophold's approach is built directly into solution-processable perovskite “inks,” enabling low-cost, scalable manufacturing, including roll-to-roll printing. 

Twophold is partnering with perovskite developers to integrate and optimize this technology in real devices - delivering higher efficiency at no added cost and a step-change reduction in $/W.
