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.
Solar startup claims doubled energy per acre with terrain-following 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.
Princeton NuEnergy scores $30 million in funding for lithium battery recycling
The low-temperature plasma-assisted separation process, developed at Princeton University and now trademarked as LPAS, produces battery-grade cathode and anode materials suitable for direct reintroduction into cell manufacturing.
Longi claims 34.6% efficiency for perovskite-silicon tandem solar cell
The European Solar Test Installation (ESTI) confirmed Longi’s achievement of a world record-breaking efficiency rating of 34.6% for a perovskite-silicon tandem solar cell.
Long-duration stability of perovskite solar cells
US scientists have analyzed the impact of “seasoning” a formamidinium lead iodide solution with two-dimensional (2D) perovskites. They have found that the template improved the efficiency and durability of their solar cells.
Swift Solar closes $27 million in funding, plans perovskite solar factory
Swift Solar, a specialist in perovskite tandem photovoltaics, plans to build a factory in the U.S. in the next two to three years to manufacture thin-film solar.
Sunrise brief: Utility-scale solar far less costly than the cheapest fossil fuel source
Also on the rise: Five Puerto Rico reservoirs could host 596 MW of floating solar. Weather-related damage to solar assets exceed modeling expectations by 300%. And more.
Five Puerto Rico reservoirs could host 596 MW of floating solar
Potential sites for solar in Puerto Rico include reservoirs, brownfields, closed landfills, fossil generating plants after closure, and transmission rights of way, determined analysis by the National Renewable Energy Lab.
Concentrator photovoltaic module based on surface mount technology
A research group in Canada has optimized the performance of concentrator photovoltaics by using the so-called surface-mount technology for thermal management. The CPV module prototype utilizes four non-interconnected III-V germanium cells, a Fresnel lens, and a transparent glass printed-circuit board.
Flexible interconnection with curtailed output can benefit everyone, analyst says
Allowing flexible interconnection for large solar projects can reduce costs and speed deployment, benefiting developers, ratepayers and utility staff, said a presenter at a North Carolina conference of utility regulators.
