Chinese PV Industry Brief: Microquanta builds 12 MW ground-mounted project with perovskite solar modules
In other news, Haiyuan Material (HYM) said it will commission its 600 MW heterojunction cell factory in July and Polysilicon supplier Daqo announced it is seeking to raise RMB11 billion ($1.74 billion) through a share private placement.
Novel IBC solar cell architecture based on crystal photonics shows efficiency potential of 29.1%
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%.
Work begins on world’s second largest PV system on a stadium roof
The stadium of German football club SC Freiburg will host a 2.4MW rooftop solar array that will be built with heterojunction modules provided by Swiss manufacturer Meyer Burger.
Photovoltaics for underwater wireless communication
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.
Mobile solar pump for remote areas
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.
All-polymer solar cell with 15.53% efficiency via meniscus-assisted coating
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.
Flexible solar panels made in Israel for Amazon’s facility in France
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.
Rooftop solar price to keep rising this year
British analyst GlobalData has predicted residential and commercial rooftop panels will not return to a declining price trend until next year, with post-Covid logistics headaches the cause, rather than a polysilicon shortage.
TOPCon solar modules in MENA
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.
Longi unveils 415W solar panel with 21.25% efficiency
The new product is mainly intended for use in commercial and industrial solar projects. It has a size of less than 2m² and features a short-circuit current below 15A.
