The Future, Now: Perovskite Technology advancements at Caelux

Residential solar installations recently completed their sixth consecutive record year, growing by 40 percent year-over-year and adding 5.9 GW of renewable energy capacity to American homes.

As solar power solutions continue to increase, there is a growing demand for more efficient, resilient, and cost-effective products to power our communities, something made even more evident as the Inflation Reduction Act provides meaningful financial incentives not only for consumers to adopt solar technology but also investors interested in accelerating the adoption of energy-efficient products.

To achieve continued growth while improving results and long-term sustainability, the industry can’t rest on its laurels. It must embrace the innovative and imaginative spirit that defined the past several decades of solar power design and distribution.

Today, these developments are more tangible than ever before.

In the world of renewable energy, perovskite technology has long been considered a future possibility.

However, Caelux Corporation has made incredible advancements in this technology over the past six years, creating a more near-term solution than previously thought possible and allowing for imminent deployment at scale. To bring this innovation to market, we are building a manufacturing facility in Baldwin Park, California, and ramping up to reach 100MW of perovskite-coated glass by the summer of 2024.

Caelux Achieves R&D Breakthrough

Consumer grade, production scale perovskite technology required a significant leap in module development. Over the past two years, Caelux’s R&D team has made tremendous progress, increasing the size of our perovskite-coated PV glass 400x, allowing us to start producing solar power devices that third-party labs and customers could test.

This includes developing manufacturing processes that are inherently scalable and cost-effective and creating prototype devices that look and perform like full-size commercial solar modules.

At the same time, the efficiency of these devices has increased considerably, and Caelux has partnered with the University of California Advanced Solar Technologies Institute (UC Solar) Merced Test Labs to analyze our prototypes using purpose-built, outdoor testing structures.

Of course, real innovation must move beyond the lab setting. To that end, we have propelled our product beyond traditional laboratory fabrication techniques and into scalable production methods, which mirror production processes.

While early efforts by the Caelux R&D team only experienced single-digit efficiency gains, more substantial developments emerged. Eventually, our team demonstrated that Wright’s Law is applicable to this emerging technology, which shows a fixed improvement ratio every time the output doubles.

Every time we doubled our output, there was a fixed improvement ratio. We saw a 12-15% improvement every time we doubled our cumulative output, which aligns well with learning rates in the photovoltaic industry.

Today, we produce semi-transparent devices with greater than 16 percent power conversion efficiency.

At the same time, we are paying close attention to durability, making steady progress toward deploying perovskite PV glass that supports our customers’ robust warranty commitments. We’ve tested our materials system outdoors for nearly two years, collecting data and driving improvements.

Taken together, Caelux has achieved tremendous progress in developing perovskite technology by improving the efficiency and scalability of their solar modules and focusing on durability, producing solar power devices that can be easily deployed. With a full product launch scheduled for Q4 2024, Caelux is quickly advancing the timeline for bringing perovskites to the market.

Implications for the Value Chain

These advancements in perovskite technology have implications for the entire value chain.

By working with module makers and turning competitors into partners, Caelux has created a “win-win-win” scenario where the consumer and project developer benefit from lower installation costs and increased energy output. Meanwhile, increased module power conversion efficiency ensures manufacturers can sell their products for a higher price.

The company’s full-release product, Caelux™ One- a >17% efficient PV glass- will enable solar manufacturers to sell more robust products with warranties that meet market norms.

Our solution is straightforward for our solar module customers to implement. With a few small process changes in module assembly, Caelux’s products can be incorporated into a module much like any typical solar glass, with no additional production equipment needed by the customer.

With Caelux™ One, a 23% efficiency solar module can become a greater than 27% efficient module; a 19% efficient module can provide greater than 26% conversion efficiency. We will enable much higher power output at the same cost per watt, unlocking tremendous value for our customers and end-users.

Emerging climate tech solutions need cheaper green electrons (Direct Air Carbon Capture, Hydrogen electrolysis, and electric vehicle charging micro-grids). Caelux’s advancements in perovskite technology can lead to a more diverse range of solar products and applications, expanding the market for solar power beyond traditional residential and commercial installations. This diversification can increase demand for solar power solutions, benefiting the entire value chain.

Caelux’s R&D breakthrough in perovskite technology has significant implications for the entire value chain in the solar power industry. The advancements in scalability, efficiency, and durability can lead to lower installation costs for customers, increased revenue for module makers, a more diverse range of solar products, and potentially disrupt the current dominance of silicon-based solar technology.
