[SMM PV News] Yunnan Wenshan: Launches Selection of 290 MW Wind and Solar Projects

The team led by Academician Li Yongfang and Researcher Meng Lei at the Institute of Chemistry, Chinese Academy of Sciences, recently successfully fabricated high-performance perovskite–organic tandem solar cells, achieving a steady-state photoelectric conversion efficiency of 28.04% and marking a key step toward practical application. The result has been published in the international academic journal *Nature*. Perovskite–organic tandem solar cells are constructed by stacking a wide-bandgap perovskite subcell and a narrow-bandgap organic subcell in series, allowing them to absorb sunlight across different wavelength bands and thus break the efficiency limit of single-junction solar cells. The efficiency improvement of such cells has long been hindered by issues such as large voltage loss in the wide-bandgap perovskite front subcell and insufficient stability. To address the efficiency challenge, the research team proposed a “full-stage regulation” strategy, designing and introducing photoconvertible additive molecules that promote uniform mixing of perovskite components, bind more firmly to the perovskite surface, and effectively suppress phase segregation under illumination.

Recently, the Department of Industry and Information Technology of Jiangsu Province announced the list of 2026 Advanced Smart Factories in Jiangsu. Three factories under CSI Solar (688472) were successfully selected, fully demonstrating the company’s leading strengths in smart manufacturing, digital transformation, and industrial innovation applications. To date, Canadian Solar Inc. has nine factories recognized as Jiangsu Provincial Advanced Smart Factories, covering core business areas such as PV wafers, cells, modules, and energy storage, further highlighting the company’s remarkable achievements in continuously advancing intelligent upgrades and high-quality development in the new energy manufacturing sector.

Previously, JA Solar Technology upgraded and launched the 'Blue Desert' professional PV module, specifically designed for the harsh desert-Gobi-wasteland environment. Recent empirical data shows that the power generation per watt of this module increased by 2.56% (Tengger Desert) and 3.98% (Ulan Buh Desert) compared to conventional modules. The upgraded module, through three major technological innovations—nano-scale self-cleaning coating, open-type steel frame, and UV light conversion film (optional)—achieves self-cleaning by wind and rain, self-repairing against wind and sand, and converts harmful UV light into visible light to combat degradation and enhance efficiency. Based on the DeepBlue 5.0 platform, this module reaches a maximum power of 670W, aiming to reduce the cleaning and operation and maintenance costs of desert-Gobi-wasteland power stations and achieve deep integration with the desert ecosystem.
