perovskite solar cells

Chinese researchers developed an all-perovskite tandem solar cell using a non-contact laser polishing strategy that reduces surface defects and improves charge extraction in lead-tin perovskite films. The device achieved up to 29.80% tandem efficiency, with the bottom cell improving from 19.64% to 24.07% and showing strong operational stability under continuous illumination.

The proposed inverted perovskite solar cell design reduces band misalignment and electron accumulation, suppressing recombination losses and enabling high efficiency in both small-area devices and scalable modules.

Japan’s New Energy and Industrial Technology Development Organization (NEDO) has opened a supplementary call for proposals on mass production of next-generation single-junction perovskite solar cells, with submissions due by June 3.

An international research team has proposed a perovskite solar cell architecture incorporating a thin tetraphenyl-porphine zinc interfacial layer to enhance surface potential, passivate defect states, and improve charge transport. The strategy leads to improved device efficiency and operational stability, enabling power conversion efficiencies exceeding 13%.

Swansea University researchers found that perovskite solar cells can tolerate dusty fabrication environments, performing almost as well as those made in cleanrooms. The findings suggest low-cost, scalable production may be possible without ultra-sterile conditions, potentially accelerating cell and module manufacturing.

Scientists at the European Commission Joint Research Centre tested two single-junction perovskite modules outdoors for one year and reported overall stable performance, supported by a new light-soaking preconditioning method to improve measurement reliability. While one module degraded significantly, the other maintained relatively stable efficiency with seasonal variations, highlighting the need for longer-term outdoor studies.

pv magazine spoke with Fan Bin, founder of GCL Optoelectronics, about how high-throughput experimentation and AI-driven optimization are accelerating perovskite development, and why stability, and not efficiency, remains the key challenge on the path to mass production

The UK-based perovskite solar PV specialist has announced a new metrology research project with Swansea University and a new development agreement with Renolit, a German plastic films, sheets and polymer solutions company.

GIST researchers have developed a perovskite mini-module with 22.56% efficiency by improving the SnO₂ electron transport layer with PEI, reducing defects and electron loss. The module retained 94% of its performance after 500 hours, highlighting potential for scalable, stable perovskite solar cells and modules.

Researchers at Hebrew University of Jerusalem have demonstrated 9.2% efficient printable semi-transparent, flexible halide perovskite solar cells with tunable color and transparency.
