A major breakthrough in energy transformation was achieved in the development of the tandem solar panel. The solar panel shows an impressive 25% efficiency, which is one percentage point more than the efficiency of the best commercially available models. Interesting Engineering magazine provides details.

According to a press release from Oxford PV, it is currently the world’s most efficient tandem silicon-perovskite solar cell. “This new world record is a major milestone for Oxford PV, proving that our tandem solar cells can achieve record performance when assembled into solar panels.” said managing director David Ward.

Oxford PV is known for its pioneering work in tandem silicon-perovskite solar cell technology. To achieve this goal, it collaborated with the German Fraunhofer Institute for Solar Energy Systems.

421 watts on an area of ​​1.68 square meters

The press release highlights that the tandem solar array achieves performance up to 421 watts on an area of ​​1.68 square meters. “Our record solar panels prove we are on the cusp of the next revolution, driven in part by our tandem cell technology,” says the company’s chief technology officer, Chris Case.

CalLab PV Modules used a multispectral solar radiation simulator for calibrated measurements and determination of module efficiency. In order to accurately and reproducibly express the performance, both the perovskite and silicon layers of the cells were illuminated by different LED light sources under conditions as close as possible to the conditions for generating electricity from natural sunlight.

“Solar energy is currently one of the most cost-effective and sustainable sources. Our continuous technological progress will further increase the efficiency of the modules which they will be able to produce more electricity on the same areaand expand their use to all market sectors from residential, commercial to municipal,” Case concluded.

Achieving high conversion rates

The increasing efficiency of photovoltaic panels is evidence of the continued progress in solar technology. With the growing demand for renewable energy sources, achieving the highest possible conversion ratios becomes a competitive advantage in this segment. The effort to increase the conversion rates of solar panels is based on the basic goal of maximizing the efficiency of converting sunlight into electrical energy.

Whereas the solar power will account for three-quarters of global renewable capacity additions in 2031, increasing the efficiency of solar panels has significant potential. Among other things, more efficient panels will reduce electricity costs and further accelerate the introduction of clean energy.

2024 will be a pivotal year for Oxford PV as the firm expands production and continues plans to build a new factory to produce high-volume tandem solar cells. “This is the first step in 2024, when we will start supplying panels to the market from our factory in Germany, and we will continue to search for a new production plant for series production, which will allow us to bring our technology into normal operation.” Ward said.
