Yongjia Photon closes Series A for perovskite solar cells, led by Planck Ventures
What's the deal? Yongjia Photon (永珈光能), a Chinese startup developing high-efficiency perovskite solar cell technology, has closed its Series A funding round. The investment was led by Planck VenturesDealroom has a profile for this one. Try Dealroom →.
The company focuses on stable, high-efficiency single- and multi-junction integrated perovskite solar cells. It has achieved a power conversion efficiency (PCE) above 26% for single-junction perovskite cells and above 27% for all-perovskite tandem cells. Its devices have demonstrated continuous light-soaking stability exceeding 6,000 hours.
Why now? Perovskite solar technology has emerged as one of the most promising frontiers in renewable energy. Unlike traditional silicon cells, perovskite cells can be manufactured at lower cost and applied to flexible surfaces — but stability has long been the technology's Achilles heel. Yongjia Photon's 6,000-hour stability milestone addresses that concern directly, making it an attractive bet for investors.
China dominates the global solar supply chain and is aggressively funding next-generation photovoltaic technologies to maintain that lead.
What could go wrong? Perovskite cells still face significant hurdles on the path from lab to commercial scale. Degradation under real-world conditions — heat, humidity, UV exposure — remains a challenge, even for companies posting impressive lab results. The market is also increasingly crowded, with well-funded competitors across China, Europe, and the US racing toward commercialisation.
The signal: Venture capital continues to flow into perovskite solar technology as the sector inches closer to commercial viability. Yongjia Photon's round reflects broader confidence that the efficiency and stability gaps between perovskite and silicon are narrowing fast enough to justify early-stage bets. If tandem perovskite cells deliver on their promise, they could reshape the economics of solar energy within the decade.
