The new development is based on a tandem architecture that combines two types of photovoltaic materials, according to pv magazin. The top perovskite layer absorbs the high-energy portion of the solar spectrum, while the bottom silicon layer converts the light that passes through the top layer. This approach allows for more efficient use of solar radiation compared to traditional silicon panels.
The development was presented amid growing industry interest in perovskite technologies. Silicon solar cells remain the backbone of the global photovoltaic market; however, much of the research in recent years has focused on finding ways to improve their efficiency through the use of additional materials and multilayer structures.
According to the company, the use of perovskite in combination with silicon opens up opportunities for further increases in solar module efficiency. At the same time, the prospects for commercial implementation of the technology will depend not only on performance but also on manufacturers’ ability to ensure stable panel operation over the long term.
The durability of perovskite materials remains one of the key challenges for the industry. Experts continue to study their resistance to moisture, high temperatures, and ultraviolet radiation. This factor is considered one of the most critical for the widespread adoption of this new technology in the market.
The results presented by Trina Solar demonstrate the ongoing development of tandem solar modules. Industry participants view the combination of silicon and perovskite as one of the avenues for further improvement in solar energy, but the prospects for widespread adoption of the technology will depend on the results of its commercial operation and confirmation of the claimed performance characteristics under real-world conditions.
