Huge solar panels with 20.6% efficiency set a world record: what is known

Scientists have developed a technology to produce highly efficient large-area perovskite solar cells. This — breakthrough in panel efficiency.

Researchers from South Korea set a new record for the efficiency of a large-area perovskite solar module. About it writes Interesting Engineering.

The Korea Research Institute of Chemical Technology (KRICT) and UniTest Co. have jointly developed a technology for manufacturing high-efficiency large-area (over 200 cm2) perovskite solar cells that have achieved a certified efficiency of 20.6%. The new technology breaks the previous world record of 19.2% set by UtmoLight.

The Fraunhofer Institute in Germany officially certified the record, which was listed in the “Champion Module Efficiency Chart” of the U.S. National Renewable Energy Laboratory (NREL).

KRICT says that with UniTest, it is preparing to mass-produce perovskite solar cells for various applications such as indoor photovoltaics, building-integrated photovoltaics (BIPV) and other functional devices, with some products expected to enter the market this year .

The KRICT research group has optimized its in-house materials synthesis methods, film uniformity through scalable processes and laser ablation control, which resulted in a certified efficiency of 20.6% for large area (>200 sq.cm) perovskite solar modules, significantly exceeding the previous record of 19.2%.

Perovskites — are materials that have shown potential for high performance and low manufacturing costs in solar cells.

The name “perovskite” comes from the nickname for their crystal structure, although other types of nonhalide perovskites (such as oxides and nitrides) are used in other energy technologies such as fuel cells and catalysts, according to the US Department of Energy.

Periodescent solar cells have shown significant progress in recent years, with efficiency levels increasing rapidly. However, despite their rapidly increasing efficiency, several challenges must be resolved before they can become a commercially competitive technology.

“This achievement is an important milestone in overcoming one of the key technical barriers to the commercialization of large-scale perovskite cells , marking a major success in the collaboration between industry and scientific research, which we hope will make a significant contribution to the commercialization of solar cell technologies,” — said KRICT President Young-Kook Lee.
