The EU-funded Laperitivo project aims for 22% efficiency in 900 cm² opaque perovskite modules and 20% efficiency in semi-transparent ones. The project partners include imec, Fraunhofer ISE, TotalEnergies, and EDF.

By coating the iron sulfide cathodes in polymers, a research team was able to create transition-metal sulfide-based lithium batteries with stable cycling and high safety. After 300 cycles, a lithium carbide iron disulfide pouch cell retained 72.0% capacity with no capacity degradation after 100 cycles.

GE Vernova has developed a 2,000 V (DC) utility-scale inverter, to be used in a North American pilot operation starting in early 2025. The inverter offers up to 6.0 MVA of output power.

Researchers have measured the power loss of a 50 W panel stationed in a 30-meter wave tank. Based on ten different scenarios, they were able to draw an empirical equation for the prediction of power loss, with the highest loss being measured at 12.7%.

The Hungarian government says 20,000 households have signed up for its PV subsidies scheme, which offers up to HUF 5 million ($14,125) per home installation. The original HUF 75.8 billion budget was increased by HUF 30 billion in July.

German fluid management company Lutz-Jesco introduced a system aimed at supporting pumping and water disinfection in cases of blackouts. The hub is preconfigured to work with solar panels, a battery charge controller, an inverter, and cabling.

The novel method uses the YOLOv8 framework, integrating an attention mechanism and a transformer model. It was tested on a dataset of 4,500 electroluminescence images against several other models and its results were up to 17.2% more accurate.

Scientists have proposed a new system that uses surplus PV energy in the spring and the autumn to charge up underground thermal energy storage for later use in the summer and winter. They have simulated it on a school facility in Seoul, with a few optional configurations for thermal storage. Power savings were up to 39%.

New research from India shows how bifacial solar modules should be deployed to achieve strong performance in floating PV projects planned on tropical freshwater. Their experimental setup demonstrated that higher efficiency gains are achievable by gauging panel height, water depth, and tilt angle.

Researchers have used the chimp optimization algorithm to optimize the hyperparameters of five PV power yield prediction machine learning models. This algorithm is based on the cooperative hunting behavior of chimpanzees in nature, mimicking the way they work together to target prey.
