ONGi, a leading force in solar cell manufacturing, has shattered the world efficiency record for crystalline silicon-perovskite tandem solar cells, hitting an impressive 33.9% conversion rate. This new peak in efficiency not only surpasses the benchmark set by King Abdullah University of Science & Technology (KAUST) earlier this year but also eclipses the infamous Shockley-Quieser limit that's long been the glass ceiling for solar tech.

For decades, the solar industry has been fine-tuning silicon-based cells, pushing conversion efficiency higher and higher. Yet, as we've inched closer to the Shockley-Quieser mark, a theoretical 33.7% efficiency limit for single-junction hbc solar cells, the progress was slowing to a crawl. However, the introduction of new silicon-perovskite tandem cells has sparked a new surge in the industry, promising efficiency heights of up to 43%. This technology is now seen as the key to unlocking new levels of solar performance.

The U.S. National Renewable Energy Laboratory (NREL) has officially confirmed LONGi's groundbreaking record in tandem solar cells, marking a notable advance from their previous milestones of 31.8% announced at SNEC 2023 and 33.5% at InterSolar Europe 2023.

This isn't LONGi's first rodeo. Only a year ago, they made waves with 26.81% efficiency for silicon heterojunction cells. With their latest achievement, the manufacturer now secures its spot as a record-setter on two solar fronts and solidifies its status as a heavyweight in solar efficiency.
