Caelux

Caelux is a Khosla Ventures backed start-up company based in California. It was founded in 2014 as a spin-out of Caltech.

Caelux's mission is to catalyze the Integrated Power Enhancement solar market category by deploying perovskites technologies at a global scale. It is working on creating scalable, affordable and high-efficiency perovskite solutions.

Caelux attaches the silicon surface to the perovskite in parallel, so the currents are additive, and only the voltage has to be matched.

Caelux expects to reach the rooftop market first, and then the utility and C&I markets subsequently and is setting up a 50 MW prototype line, which can scale to 100 MW when run at 24/7. It will then build up in 100 MW units around the country, placing manufacturing near the customers. One of those 100 MW lines is meant to cost the company around $5 million.

The company wants to be self-funding by 2023 and then go for a 300 MW to 600 MW production capacity and shift to multi-GW by 2025.
