Indian researchers have developed a Sudoku-based technique to reduce power losses in PV systems operating under partial shading. They claim the method increases energy efficiency and revenue generation more than conventional reconfiguration techniques.

Maximizing value from battery energy storage systems (BESS) isn’t just about having the right hardware – it’s about executing the right strategy. Lennard Wilkening, CEO and co-founder of Germany’s suena energy, explores what makes standalone BESS profitable in increasingly competitive and volatile market, and what real-world benchmarks, such as suena energy’s monthly revenue update, reveal about the role of dynamic multi-market optimization.

A group led by Cambridge University has developed an adhesive-free method of bonding ultra-thin gallium arsenide solar cells to borosilicate glass. The proposed technique is reportedly compatible with standard planar device processing.

Researchers at the Ecole Polytechnique Fédérale de Lausanne (EPFL) have proposed combining the two high-temperature steps used in producing tunnel oxide passivated contact (TOPCon) solar cells into a single co-annealing process. Initial results show promising outcomes in boron concentration, passivation quality, and contact resistivity.

Researchers have designed a new switched-capacitor-based multilevel inverter topology with nine switches. They have tested it in simulations and in hardware-in-the-loop tests. Efficiency reached up to 96.5%.

Scientists in Hungary have built an experimental rig that uses a 60 W polycrystalline solar panel with 152 holes drilled into its frame for air cooling, as well as high-conductivity copper alloy pipes and fins placed on its back for water cooling.

Researchers in Taiwan have developed an adjustable aluminum reflector system that boosts the performance of vertically mounted bifacial solar modules. The prototype delivered a 71.32% total power gain over a baseline system without reflectors.

An international research team has conducted an extensive overview of bifacial solar modules from 39 countries. Their analysis took into account the best of the median values indicated in the product specifications and found that heterojunction and back-contact panels provide the best parameters.

The US-based company says its new AeroTherm G2 uses both electric and heat-pump-based heating. It ranges from 189 L to 303 L in capacity.

The Chinese company stated that its new H02 product line is available in either single-phase or three-phase configurations. It comes with a different number of 5.12 kWh batteries.
