Stable market leadership, faster N-type adoption, and resilient Ex-China demand lift global PV module shipments to approximately 260 GW in the first half of 2026.

N-type expansion, Ex-China demand, and growing concentration among specialized manufacturers reshape the PV cell shipment landscape in the first half of 2026.

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.
