Developed by a Vietnamese-Korean research group, the complex PV device was built with a bottom bifacial crystalline silicon perovskite-filtered heterojunction sub-cell that is able to absorb all solar spectra in the short-wavelength range.

The Swiss group has acquired an integrated solar roof system solution from an unidentified German engineering service provider for this purpose. The aim is grow this sector from a niche market.

The energy payback time of a silicon PV rooftop system mounted in India is only 0.44 of one year (160.6 days), compared to 0.53-0.67 year in Africa, 1-1.3 years in Europe, and 1.42 years in Canada, reveals a world map by German research body the Fraunhofer Institute of Solar Energy Systems (ISE). For the calculation, the report authors considered the installation used a typical, Chinese-made, 60-cell, PERC, 19.9%-efficient solar module.

Australia-based Fortescue Future Industries has partnered with JSW Energy arm on green hydrogen production and application in India. 

Professor Thomas Nann told pv magazine Australia that a breakthrough idea was almost too simple: “Actually when we submitted the patent in the first place, the patent officers came back to us and said ‘well, that’s too trivial’ and we made exactly that argument – why did no one else do that then?” said Nann.

With manufacturing ramping up year by year and policies already looking to get ahead of the large volumes of end-of-life products, the landscape for lithium-ion battery recycling is rapidly changing. pv magazine recently spoke with Mari Lundström, associate professor of chemical and metallurgical engineering at Aalto University, to find out what is needed on the research side for the effective recycling of batteries.

The manufacturer has launched sodium-ion products online. Production has begun and will be easily scalable, according to the CATL chairman. Researchers have been keen to make the technology work as it offers a cheaper, more environmentally friendly alternative to lithium-ion products.

The PV mounting system was developed by Germany-based Goldbeck and will initially be available in the Netherlands from 2022. The company will test the new technology in a 45 MW PV project.

The Indian solar manufacturer has released the Helia series of high-efficiency mono PERC PV panels. Ranging from 450W to 600W outputs, the multi-busbar modules are designed for use in residential, commercial and utility-scale installations.

According to a new report, India’s commercial and industrial sector will increase its rooftop solar deployments by 47% year-on-year, with bifacials and large-size high-wattage modules offering cost-effective support for reducing electricity costs.
