PV modules

A British-Swedish research team has reviewed all models for designing and simulating solar-powered heat pumps systems of various complexities. Based on this work, the scientists proposed a new method combining five models across multiple computer programs into a single analysis tool that reportedly produces accurate critical metrics for technical, economic, and climate impact analysis.

University of New South Wales researchers investigated the impact of sodium-induced degradation in heterojunction solar cells under accelerated damp-heat testing. They considered three different types of sodium salts and identified the degradation mechanisms attributed to each contaminant.

The reason given for the shutdown is the inability to “improve the level of some key impurities,” and would not be able to deliver a quality product in the time demanded by the company’s main customer.

The International Energy Agency’s (IEA) Photovoltaic Power Systems Programme (PVPS) highlights key performance indicators (KPIs) for PV systems in its latest report. It calls for clear KPI definitions and standardized data handling to enhance system efficiency and reliability.

As the penetration of variable renewable energy increases, curtailment of solar PV generation will only increase. Since curtailment will almost always be cheaper than investing in new transmission capacity or new grid-scale storage, curtailed energy should be rewarded, so that PV investment decisions can include curtailment as one of the flexibility options for grid operators.

Researchers in China claim to have built a perovskite solar cell that can effictively reduce ion migration and offer superior stability. The device utilizes an ultrathin membrane made of a polymeric material known as PDTBT2T-FTBDT (D18), which reportedly offers conformal coverage on the surface of perovskite film due to its high fluidity.

Norway’s Mer Group has installed a pilot EV charging station with a timber canopy in Spittal an der Drau, Austria, in collaboration with local partners.

Scientists have developed a multi-physics thermal model for panels with a natural convection cooling loop and tested it against experimental data. They have also experimented with varying the coolant channel thickness and different coolants. The highest measured electrical efficiency reached 15.45%.

Research from the Chin-Yi University of Technology in Taiwan revealed a novel heater design in the Czochralski silicon crystal growth process that can control and decrease oxygen concentration without incurring the costs associated with other methods, such as installing magnets or using alternative crucible materials.

Japanese plastics manufacturer Sekisui Chemical is investing in a 100 MW production line to make lightweight perovskite solar panels for low load-bearing rooftops, with an operational start in 2027. It will also acquire a production facility from Japanese electronics manufacturer Sharp.
