Perovskite solar panels developers


Aerosolar is a spin-out from Queen Mary University of London, founded in July 2022, that aims to commercialize a new aerosol-based treatment for making perovskite solar cells more affordable and efficient.

The aerosol-assisted solvent treatment has been developed by professor of Energy Materials and Devices at QMUL Joe Briscoe and his team. It involves passing dimethylformamide solution (alone or with added methylammonium chloride) over a surface in a controlled manner before passing through a reactor containing the heated perovskite sample. This takes no more than five minutes and can also facilitate processing at a lower temperature (100 degrees C) compared to direct thermal annealing.

This approach can significantly enhance the grain growth of perovskite cells, reducing local defects and improving overall uniformity. The treated perovskite cells also exhibit remarkable performance improvements, with increased efficiency and stability across various compositions, device structures, and areas. It also makes these cells more affordable and easier to mass-manufacture.

Looking ahead, Briscoe's team is conducting further tests to assess the long-term effectiveness of this process and its scalability for commercial applications. The plan is to optimize the aerosol-assisted solvent treatment in a large-area reactor, paving the way for the development of cost-effective, lightweight, and flexible solar cells at a commercial scale.

Caelux company logo imageCaelux 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.
