perovskites solar cell factory quality control

Caelux was founded in 2014 with a vision of building better-performing crystalline silicon solar modules. As a team of scientists and engineers focused on creating a greener future through powerful solar technology, our goal was to pave the way for next-generation solar panels.

We partner with our module customers to unlock the next level of module efficiency while not sacrificing durability. We understand module assembly and have developed our solution with our customer’s exacting processes and standards in mind.

Our customers consign their solar glass to us where we apply our proprietary film stack and processing technique to transform the substrate into a perovskite active glass. The active glass is then used by our customers in much the same way as any other solar glass, but with substantially improved performance.

How We Build Perovskite Solar Cells

At Caelux, efficiency and durability are our priorities. It’s the driving principle behind every design, starting at the concept stage.

Caelux provides the simplest path for module companies to leverage advanced perovskite technology to boost their product’s performance.

Caelux uses a four-terminal, passively connected architecture where the silicon and perovksite active glass are connected in parallel. While this is referred to as a four-terminal architecture, the connection is made inside the module or the junction box; there are only two leds coming from the junction box.

For module manufacturers to use Caelux’s products, there are few process changes needed in module assembly and is compatible with nearly all crystalline silicon solar cells today.

Four-terminal offers an elegant solution over two-terminal approaches, eliminating the need for specialty silicon, and reducing costs while at the same time delivering a module that is more powerful and cost effective.

Perovskite Solar Reliability

You might have heard that perovskite solar cells aren’t reliable or that they degrade rapidly. Perovskite durability used to be measured in terms of ‘seconds’ and ‘minutes’ but today they are measured in terms of years and improving.

As with every other kind of technology, perovskite solar cells are continually being improved. You could even say that’s kind of our thing. Caelux has partnered with leading institutions and laboratories to evaluate our materials and unlock ways to push them even further. We also maintain ongoing relationships with our customers to ensure our products meet their exacting standards for quality and reliability. Through our rigorous evaluation program, we’ve collected thousands of hours of operating data in real world environments. With the launch of CaeluxTM One, our products will be able to support our customer’s warranty requirements.

Caelux is Scalable by Design

Caelux™ One is an innovative product that integrates seamlessly into existing photovoltaic module manufacturing processes to boost performance, reduce installation costs, and accelerate the proliferation of lower cost solar panels. Our perovskite technology is compatible with new silicon photovoltaic modules at all deployment sites.
