Technology and R&D

Production for the HyDeal project is planned to start in 2025; the total installed capacity is expected to reach 9.5 GW of solar power and 7.4 GW of electrolyzers by 2030. Elsewhere in the world, India and Brazil are preparing rules and laws to promote green hydrogen, while research activities continue to increase hydrogen fuel cell’s efficiency and hydrogen’s use in the aviation sector.

US start-up mPower Technology is scaling up its flexible crystalline silicon solar module technology for spatial and terrestrial applications. The back-contact solar panels consist of micro-singulated silicon dies that are “hyper-interconnected” in series or in parallel. The devices have efficiency ranging from 22 to 23% depending on the size or applications.

Chinese manufacturer Bslbatt has unveiled a modular lithium-ion battery that can be used for the off-grid storage of solar energy. The device has a storage capacity ranging from 5.1 to 30.7 kWh and is claimed to provide steady operation for up to 6,000 charge cycles.

Scientists in Germany designed a poly-Si on oxide (POLO) interdigitated back-contact (IBC) solar cell integrating photon crystals and found this architecture has the potential to reach a power conversion efficiency of over 28%, which would be 1% higher than the current practical limit set by the scientific community. They also found that by improving passivation, the efficiency may be raised up to 29.1%.

Southern California Gas Company is submitting an application to build a 10 to 20GW electrolyzer and 25 to 35GW of new and curtailed wind and solar, along with 2GW of energy storage, to deliver green hydrogen to the Los Angeles Basin.

The list of planned gigawatt-scale battery cell manufacturing plants in Europe has grown, with Anglo-Korean battery maker Eurocell announcing plans for a gigafab in Western Europe to start manufacturing at scale within 12 months.

Researchers in China used commercially available solar cells to create an underwater optimized lens-free system for high-speed optical detection and have found that the PV devices enable a much larger detection area than commonly used photodiodes.

Called Tracker Sun Hunter, the new factory will be located in an area of over 30,000 square meters inside Enel’s Montalto di Castro power plant which is no longer used for energy generation.

Researchers at the Indian Institute of Technology Bhubaneswar have developed a solar power system that can be easily moved between farms to pump water for irrigation. The kit comprises solar panels and an inverter to power a surface-mounted pump.

Scientists in China have developed an organic, all-polymer solar cell with a special meniscus-assisted coating technique. They claim that the power conversion efficiency of the cell is the highest among solution-printing-based, all-polymer solar cells.
