Small cracks have negligible effect on solar cell performance
UK researchers have found that crack percentages of up to 11% have a very limited impact on solar cell performance. They also ascertained that hotspots are likely to arise when the crack percentage is in the range of 11 to 34%.
There’s big money in recycling materials from solar panels
Recycling solar panels keeps them out of landfills, but also provides much-needed raw materials with Rystad Energy projecting a value approaching $80 billion by 2050.
US government invests $56 million in solar manufacturing and recycling
The initiatives will support recycling processes, manufacturing perovskite PV cells, boosting thin-film cadmium telluride module manufacturing, and creating easier and more effective pathways to commercialization.
Applying perovskite solar cells onto BIPV steel products
Swansea University will collaborate with Indian multinational Tata Steel to investigate perovskite solar cell materials that could be applied directly onto coated steel to make building-integrated PV components. The partnership will add to an “active buildings” project that the Welsh university has been running for several years.
Chinese PV Industry Brief: Solar manufacturers report strong financial performances
JA Solar, TCL Zhonghuan, GCL Tech, and Ganfeng Lithium all announced increasing profits and revenue. Meanwhile, JinkoSolar expands its hydrogen business and Xinte Energy secures another big polysilicon supply deal.
Four-terminal multijunction approach for bifacial modules
Scientists tested bifacial PV devices based on silicon and gallium arsenide cells connected in a four terminal layout. They note that the four terminal design offers significant advantages over more common two terminal devices, allowing for a 17% (relative) increase in efficiency thanks to better absorption of light reaching the rear side.
DuPont Teijin Films: Recycled PV backsheets are technically viable
UP Initiative sponsor, DuPont Teijin Films is investigating closed loop recycling processes, specifically looking at how its backsheets can be recovered and used as a raw material for new production. Since 2020, it has been working on industrial trials with customers to offer rPET backsheets across its entire product range, and proof of principal trials to demonstrate the commercial feasibility of a true closed loop recycling process. pv magazine caught up with Steven Davies, EMEA market manager to discover what progress has been made in the last year.
Solar panels power the largest optical telescope in space
Our deepest view into the universe is powered by PV. NASA was one of the earliest adopters of solar technology, and it continues to be an important feature of spacecraft today.
Solar power costs continued to fall in 2021, despite rising panel prices
The average global price of solar kilowatt-hours fell 13% on 2020’s prices, as around two-thirds of the renewables capacity installed last year was cheaper than the lowest-cost fossil fuel alternative.
Novel method to turn existing solar parks into agrivoltaic facilities
An international research team has developed a new methodology to increase levels of pollination at ground-mounted solar plants. It involves the development of new vegetated land cover below and around solar parks.
