A Singaporean technology team has developed efficient repair technology that can “rejuvenate” solar cells.
Nanyang Technological University (NTU) in Singapore and the startup EtaVolt jointly developed a high-intensity light technology that can “rejuvenate” solar cells and slow down their performance degradation.
The new technology, called “Advanced Regeneration Technology,” applies strong light and controlled temperature to polycrystalline silicon molecules on solar cells, causing them to move violently to rearrange and “repair” damage caused by light, heat, and humidity. Tiny holes. It takes less than 5 minutes to restore up to 5% of the performance loss in treated solar cells.
“Like mending a leaky bucket, this process repairs the micropores of the solar cell, preventing energy leakage and ensuring optimal light energy collection,” the scientists said.
The research team says the technology can extend battery life by up to five years, depending on the battery technology. This device is not only suitable for rooftop photovoltaic systems, but also for ground photovoltaic power stations, and is compatible with about 90% of solar panels on the market.
According to EtaVolt’s official website, this new regeneration technology is based on a proprietary combination of light, temperature and regeneration time, and can also mitigate and restore light-induced degradation (LID).
“Our solar cell regeneration method has not only been rigorously tested and validated, but has also been field proven in a variety of commercial applications. The technology has been successfully used in projects with key partners in the solar industry, such as Renewable Energy Solutions Vector Green has proven its effectiveness and broad application potential,” said NTU researcher Stanley Wang.
Naijatechnews noted that the research team did not disclose more technical details about the device, saying only that “these technologies developed at NTU have been patented through NTUitive, NTU’s innovation and enterprise company, and licensed to EtaVolt.”
This breakthrough technology is expected to significantly extend the service life of solar cells, reduce the operation and maintenance costs of solar power generation systems, and bring new hope to the development of renewable energy.
