Scientists develop silver-free PEDOT:PSS adhesive for shingled solar cells
Researchers from the University of California, San Diego (UCSD) have developed a new silver-free adhesive for shingled solar cells. The novel adhesive is based the PEDOT:PSS polymer and can reportedly reduce silver consumption to approximately 6.3 mg/W.
Low prices for TOPCon solar panels put pressure on PERC
In May 2024, high-efficiency panels, predominantly glass-glass modules equipped with tunnel oxide passivated contact (TOPCon) cells began to converge on price with mainstream offerings, writes Martin Schachinger, of pvXchange. Production volumes for these negatively-doped, “n-type” cells and modules have been ramped up in China while the increasingly restrictive customs situation in the United States may already be having an impact. For the European market, ever-lower prices for the latest module technology would suggest that demand would continue to rise were it not for a number of disruptive factors.

Waaree Energies has secured a contract to supply its p-type bifacial solar modules for Acciona Energy’s 412.5 MWp (335 MW AC) project in Rajasthan.
Spontaneous glass breakage on solar panels on the rise
The National Renewable Energy Laboratory noted an increase in spontaneous glass breakage in solar panels. The PV Module Index from the Renewable Energy Test Center investigates this and other glass-related trends in solar manufacturing.
Oxford PV unveils 26.9% perovskite tandem module efficiency record
Oxford PV has announced a record-setting 26.9% efficiency for its perovskite tandem module at Intersolar Europe 2024, the continent’s largest solar and energy storage event.
Polysilicon prices stable, market concerns persist over worst-case scenario
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.
Solar dimming and brightening, and PV power plant output performance
Reliable assessment of the local solar radiation resource is a major component of large-scale PV power plant project development and financing. This assessment is usually based on the assumption that the long-term average annual solar radiation from previous years is not significantly different from the expected future solar resource availability. In many areas of the globe, the solar radiation availability in 2023 was considerably higher (up to 10-12%) than the long-term average, and this might be overshadowing the fact that a large fraction of utility-scale PV power plants is undeperforming.
U.S. startup claims doubled energy per acre with terrain-following solar array
California startup Planted Solar uses construction robots and high-density arrays to deliver what the company says are higher energy outputs and lower balance of system costs.
Aiko presents ABC solar module with world record efficiency of 25.2% at Intersolar
The Chinese back contact module maker said its new products rely on the company’s all-back-contact (ABC) cell technology and feature a temperature coefficient of -0.26% per C.
