A team of Russian researchers has unveiled a compact photoelectric module that uses a perovskite layer to power small, energy-efficient devices. The achievement was announced by the press service of MISIS, highlighting that the work was conducted at the National University of Science and Technology MISIS.
Perovskite solar cells are widely viewed as a breakthrough area in solar energy. They promise lower costs, greater flexibility, and the potential to be produced as ultra-thin films that can adhere to nearly any surface. This includes building facades and vehicle exteriors. The conversion efficiency of these cells has climbed to levels similar to silicon-based solar panels, around 25 percent, yet researchers have long faced a key hurdle: perovskite’s susceptibility to degradation when exposed to chemical interactions at the charge-transport interfaces. The stability challenge has limited long-term performance and practical deployment.
Researchers at MISIS demonstrated that adding chlorine-containing dopants to the perovskite thin film not only improves device performance, achieving an electrical efficiency around 20.1 percent, but also extends device durability to about 3,500 hours, aligning with global standards. The scientists confirmed these results on larger, industrial-scale prototypes measuring 25 square centimeters, reinforcing the approach’s scalability.
According to Danila Saranin, one of the study’s authors, the chlorine additives do not stabilize the perovskite itself when looked at in isolation. Instead, when incorporated into the full solar cell stack, the doped layers help suppress degradation pathways under intense light and elevated temperatures. This results in a metastable state where ongoing reactions occur more slowly, effectively boosting the device lifetime without compromising initial performance.
Further investigations indicate that the technology could move beyond the laboratory to produce functioning samples suitable for powering low-power electronics, such as watches and wearable sensors, in real-world settings. This progression hints at a future where compact perovskite modules could be integrated into a wide range of consumer devices, delivering reliable energy harvest in compact form factors while maintaining manufacturing viability for mass production.
In related context, researchers are continuously refining materials, interfaces, and processing techniques to maximize stability, efficiency, and cost-effectiveness. The evolving body of work underscores the potential for perovskite-based systems to play a meaningful role in energy solutions for everyday devices, potentially transforming how ordinary electronics are powered in homes, workplaces, and on the move. Attribution for the presented findings is provided by MISIS and the researchers involved, with ongoing studies and peer-reviewed reports to follow as additional validations are completed.
