Technology and R&D

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.

Apollo Power is providing its flexible solar modules for a €750,000 photovoltaic project planned by Amazon in France. Each of the module units provided by the Israeli manufacturer has a size of 2,040×6,130mm and weighs in at only 3kg/m².

In a short chat with pv magazine, Mohamed Saady Dweik, the head of technical services and product management for the MENA region at JinkoSolar, spoke about the potential of TOPCon tech in the Middle East and North Africa region. According to him, the global demand for TOPCon products may exceed that of PERC panels within three years.

Conceived for the storage of residential and large scale renewable energy, the device has a rated power of over 150mW/cm², an energy density exceeding 40Wh/L, and a power density of 72.5mW/cm². The battery was built with an anode made of inexpensive viologen and its cost, according to its creators, may be lower than $100/kWh.
