Perovskites

Tandem PV has secured capital to advance its four-terminal perovskite-silicon tandem module technology and move closer to first manufacturing. The company claims its products maintain 80% of the initial performance after 25 years.

Scientists in the United Kingdom have proposed for the first time to deposit silver nanoparticles in electron transport layers used in perovskite solar cells to improve device performance. They found that an “optimal” concentration of silver nanoparticles may help to improve a perovskite cell’s charge transfer and extraction, as well as its efficiency.

Aerosolar, a spinoff from the Queen Mary University of London, has created a novel aerosol method that it claims boosts efficiency and stability of metal halide perovskite solar cells.

Researchers at the Jülich Research Center in Germany have used novel photoluminescence measurements to analyze the recombination of charge carriers in perovskite solar cells. They have found that the loss of charge carriers in perovskite devices works differently from other types of PV cells.

Researchers from Saudi Arabia’s King Abdullah University of Science and Technology (KAUST) investigated the commercial prospects of perovskite-silicon tandem PV technologies and found that, in order to bring them closer to market maturity, their cost should not exceed by 30% that of crystalline silicon counterparts. Their roadmap stresses the importance of reducing perovskite degradation and improving product stability.

Researchers at RMIT University’s School of Science, Monash University and Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) have harnessed artificial intelligence to accelerate the design and production of perovskite solar cells.

China’s solar industry rebounded in 2023 after years of pandemic-related sluggishness. As the year draws to a close, pv magazine looks back at key highlights of 2023 and considers the prospects for 2024.

China Three Gorges has commissioned a 1 MW pilot solar plant with perovskite panels near Ordos, in China’s Inner Mongolia region. This marks the world’s first commercial PV system to use perovskite tech and features 11,200 modules from an undisclosed manufacturer.

The China National Institute of Metrology has certified the result. The manufacturer claims it was able to increase the panel efficiency from 16.02% to 18.04% in a few months.

A group of international researchers has developed a new perovskite-silicon solar cell design using a top perovskite PV device with an energy bandgap of 1.67 eV and a new self-assembly monolayer based on carbazole. The tandem cell achieved a higher efficiency compared to counterparts without the monolayer and passed the IEC 61215 standard thermal cycling test.
