Flexible perovskite solar cells ‘from lab to fab’
Scientists in Korea evaluated recent progress in the development of low cost, large scale processes for the production of perovskite solar cells on flexible substrates, finding that several challenges remain. The group recommends that research should focus on developing novel processes and materials for perovskite solar cell production, rather than adapting those already in use elsewhere.
Isomer passivation for a 21.4% efficient perovskite module
An international team of scientists trialled a new approach to passivating defects in perovskite solar cells. Using a tailored arrangement of atoms, the team was able to overcome challenges related to the formation of a two-dimensional perovskite layer on top of the active cell material, and reach 21.4% conversion efficiency for a 26cm² active area, which they claim as a record for a perovskite device of this size.

End-of-life management of solar PV waste in India
A new study proposes an ‘extended producer responsibility’ regulatory framework for end-of-life solar PV management in India.
Growatt unveils EV chargers for residential and commercial applications
The charging stations are available as both AC and DC chargers. They are compatible with all branded electric vehicles and PV modules.
Handheld dry-cleaning tool for solar modules
The handheld, cordless cleaning tool is a cost-effective and efficient alternative to automated cleaning robots that are usually limited in operation by panel inclination.
Chinese PV Industry Brief: TBEA wants to set up 400,000 MT metal silicon production
TBEA unveiled a plan to build a 400,000 MT metal silicon factory in Baotou City, in the Inner Mongolia province. Furthermore, EnergyTrend reported polysilicon prices increased slightly this week.
210mm wafer achieves highest energy yield, finds Trina Solar
Trina Solar has found that its Vertex modules, based on the 210mm wafer, achieve an energy yield up to 1.6% higher than rival products based on the smaller 182mm wafer format. The company conducted outdoor testing at two separate sites with varying climates, finding that products based on the larger format have a particular advantage in low-irradiance environments.
OCI reports strong sales growth for polysilicon business
High polysilicon prices helped South Korean supplier OCI to achieve strong results in the third quarter. Tight supply and demand conditions will likely continue until the first half of 2022, the company said.
Chinese PV Industry Brief: Daqo wiped debts as poly price continued to rise
The worldwide solar boom is proving so profitable the polysilicon manufacturer is even thinking of turning to PV panels to power its manufacturing operations, rather than cheap coal.
