Improving perovskite solar cell performance with conductive adhesive ink
Conceived by researchers from Iran, the new conductive adhesive ink is made of polymethyl methacrylate (PMMA) and is used as an interlayer between the cell’s hole transport layer and carbon foil. It reportedly ensures higher cell stability while also providing remarkable efficiency.
Photovoltaics for vapor compression refrigeration
Scientists in China have developed a PV-driven direct-drive refrigeration system for electronic device cooling. The proposed system has so far provided low exergy levels, but its costs are much lower than those of conventional vapor compression refrigeration technologies.
Sinovoltaics updates financial stability ranking of PV module manufacturers
The latest Sinovoltaics financial stability report ranking lists Tainergy, Eterbright, First Solar, Era Solar, and TSEC as the top five module makers. There was a slight reshuffling in the top ten, and seven new manufacturers were added to the ranking.
Chinese PV Industry Brief: GCL Technology posts 2023 revenue dip
GCL Technology says revenue and profits fell in 2023 due to losses on certain assets, higher financing costs, and an uptick in R&D spending.
Italy’s EU-made PV incentives raise specter of Chinese opposition
A World Trade Organization (WTO) official and several Italian lawyers recently spoke with pv magazine Italy about the timing of a potential Chinese legal challenge against Italy’s new solar measures, which exclusively provide incentives for high-performance PV modules produced in the European Union.
NREL interactive chart of solar cell efficiency now including ‘hybrid tandems’
The new cell category includes perovskite/silicon, perovskite/CIGS, III-V/silicon and perovskite/organic tandem PV devices. It will list the absolute record efficiency for all-perovskite, two-terminal tandems regardless of the number of junctions.
Climate change to drive value of rooftop solar
University of Michigan researchers have found that the value of rooftop solar will increase by between 5% and 15% by the mid-century across a range of US cities under moderate climate change, and by up to 20% by the end of the century.
New tech to demetallize, recrystallize solar cells from end-of-life PV modules
An international team of researchers has proposed a series of processes to recover silicon and other metals from recycled solar cells. Their goal is to reuse the recovered silicon in the PV supply chain.
Algorithms to detect underperforming rooftop PV panels
Australian researchers have developed multi-stage algorithms to remotely detect and accurately diagnose underperforming solar panels in residential and commercial PV systems.
Accelerated declines in solar cell prices since late March
In a new weekly update for pv magazine, OPIS, a Dow Jones company, offers bite-sized analysis on solar PV module supply and price trends.
