US EditionChinese Researchers Achieve Perovskite Solar Cell Breakthrough
Researchers reduced buried interface defects in perovskite solar cells by over 90%, achieving certified efficiencies above 26% and enhanced operational stability.
- Researchers from the Qingdao Institute of Bioenergy and Bioprocess Technology engineered a thin two-dimensional perovskite phase to enhance solar cell performance and stability, collaborating with international partners.
- Stability tests indicated that unencapsulated cells retained over 95 percent of their efficiency after 1,000 hours of continuous light exposure.
- These new 2D/3D perovskite solar cells showed high efficiencies and greater potential for commercial use.
- The researchers found that light instability in perovskite solar cells is a chemically addressable issue, not an unavoidable materials problem.

Perovskite solar cells maintain 95% of power conversion efficiency after 1,100 hours at 85°C with new molecular coating
Scientists have found a way to make perovskite solar cells not only highly efficient but also remarkably stable, addressing one of the main challenges holding the technology back from widespread use.
Buried 2D/3D heterojunction in n–i–p perovskite solar cells through solid-state ligand-exchange reaction - Nature Energy
Incorporating two-dimensional (2D) perovskite phases at the interfaces of three-dimensional (3D) perovskite solar cells improves device performance. These 2D structures form in the bulk and at interfaces of the perovskite film by adding long-chain ammonium salts into the perovskite, but achieving them exclusively at the buried interface remains challenging. Here we sequentially graft thioglycolic acid and oleylamine onto SnO2 nanoparticles. The …
Researchers boost perovskite solar cell performance via interface engineering
Researchers from the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) of the Chinese Academy of Sciences, in collaboration with international partners, have engineered a thin two-dimensional perovskite phase at the buried interface of three-dimensional (3D) perovskite solar cells (PSCs) to boost device performance and operational stability.
Golden bridge tunnel junction design boosts all perovskite tandem solar cell efficiency
Tokyo, Japan (SPX) Feb 08, 2026 A research team from the Wuhan National Laboratory for Optoelectronics and the School of Optical and Electronic Information at Huazhong University of Science and Technology has reported a new advance in all perovskite tandem solar cells, resolving a key bottleneck in tunnel junction design. All perovskite tandem solar cells are regarded as a high potential photovoltaic technology, with the
