Wafer formats continue to evolve
Differences in wafer and module specifications, which have bedevilled solar developers in recent years, could now be narrowing.
Flexible indoor perovskite solar cell achieves 32.5% efficiency
Italian scientists have developed a flexible indoor perovskite solar cell with 32.5% efficiency. Their design uses a PET substrate combined with a tetrabutylammonium bromide layer over the perovskite absorber. This additional layer effectively reduces defect density and enhances the stability of the underlying 3D perovskite structure.
Novel approach to identify silver shortages in PV industry
A Dutch-German research team has used a unique method to detect silver shortages in the PV industry. By mapping the silver supply chain from 1995 to 2021, they have identified distinct supply patterns and associated risks.
Advancing circular economy in photovoltaics: The Hot Knife PV module recycling method
Recycling is of significant importance in a circular economy, yet some challenges have to be faced when recycling PV modules. The novel Hot Knife method to separate the crystalline silicon photovoltaic module front glass from the backsheet contributes only a few permill to the life cycle related potential environmental impacts of PV electricity.
Two-terminal perovskite silicon tandem solar cell with 25.6% efficiency
The Fraunhofer ISE has developed an electro-optically optimized transparent conductive oxide layer that can reportedly improve the efficiency of perovskite-silicon tandem solar cells. A device built with the film achieved remarkable efficiency and fill factor.
Teralight announces 314 MW of new solar in Israel
Teralight, via its Solar Tech subsidiary, plans to install new solar fences, rooftops, walls and aquaculture PV projects across Israel. The projects will be built in dozens of villages.
Chinese PV Industry Brief: CNMIA reports increase in polysilicon prices
The China Nonferrous Metals Industry Association (CNMIA) says that polysilicon prices rose this week, while TCL Zhonghuan raised wafer prices for the second time in 10 days.
Prices of China’s PV upstream segments rise, module prices hold steady amid bearish sentiments
In a new weekly update for pv magazine, OPIS, a Dow Jones company, provides a quick look at the main price trends in the global PV industry.
Maxeon to build 3 GW TOPCon cell, module plant in New Mexico
Maxeon is set to invest $1 billion in the construction of a 3 GW TOPCon cell and module plant in the United States.
Brazil imported 7.8 GW of solar modules in H1
Brazilian consultancy Greener says that Brazil imported 7.8 GW of solar modules in the first half of this year, down 21% year on year. However, it says a reduction in distributors’ inventories and module prices could drive up cost competitiveness in the second half.
