Chinese PV Industry Ushers in the “Dual Tech-Star” Era, As Groundbreaking Innovations Light the Way for Cost Reduction
I. Academic Breakthrough: Perovskite Cells Overcome the "Achilles' Heel," Achieving High Lab Efficiency and Stability
Perovskite solar cells have long been viewed as a potential game-changer for next-generation PV technology due to their high theoretical efficiency, low cost, and flexible fabrication potential. However, their path to commercialization has been consistently blocked by a fundamental issue: rapid performance degradation under heat and humidity (the stability problem).
On January 9th, this impasse was broken by Chinese researchers. Their paper, titled "Molecular Press Annealing Enables Robust Perovskite Solar Cells," was published in Science. The research introduces an innovative fabrication process called Molecular Press Annealing (MPA). Unlike conventional thermal annealing, the MPA technique employs a specially designed molecular ligand (2-pyridylethylamine) to form a dense molecular template on the perovskite film surface during annealing. This molecule creates stable bidentate coordination bonds with under-coordinated lead ions in the perovskite, effectively suppressing the formation and migration of iodine vacancies that cause degradation.
This "surgical-level" precise control yielded remarkable results: small-area perovskite cells fabricated with the MPA technique achieved a certified power conversion efficiency of 26.5%. Crucially, they retained over 98% of their initial efficiency after 1,600 hours of accelerated aging under harsh conditions of 85°C and 60% relative humidity (ISOS-L-3 standard). This breakthrough is hailed by experts as a "key milestone on the path from lab to commercial application" for perovskite technology, as it tackles both high efficiency and high stability—the two core challenges—simultaneously.
The challenge lies in the increasingly stringent market demands for cell conversion efficiency, module reliability, and product differentiation. The opportunity arises from the fact that rapid technological iteration opens up space for value enhancement for companies that master core processes. Whether it's refining and optimizing existing high-efficiency technologies like TOPCon, HJT, and IBC, or closely monitoring the industrialization trends of future technologies like perovskite tandems, continuous investment in R&D and building a proprietary technological moat has become the only way to gain a competitive edge in the next wave of industry reshuffling.
Conclusion:
The two technological developments in early 2026, like two sides of the same coin, jointly reveal the core shift in China's PV industry: a transition from "rapid expansion" driven by scale to "intensive cultivation" driven by technology. The perovskite breakthrough offers a glimpse into the ultimate potential of PV efficiency, while the continuous climbing of mass-production module efficiency represents the most solid steps being taken today to reduce the cost of green electricity globally. For international clients, this means more efficient, reliable, and cost-effective PV products are constantly emerging. Partnering with technology leaders will be key to ensuring the long-term competitiveness of their energy projects.
