Message framing techniques to boost solar sales
A Dutch-German research team has tested how a series of framed messages may be used to boost PV system sales, addressing both self-interest and environmental concerns, and has found that all the proposed messages are effective at promoting the purchase of solar panel installations.
New dichalcogenide solar cell architecture promises 25% efficiency
Stanford University researchers have explored the efficiency of a single-junction solar cell using transition metal dichalcogenides such as MoS2, MoSe2, WS2, and WSe2 as absorbers. The device has shown substantial light absorptance in ultra-thin 5-nanometer (nm) films, achieving high short-circuit current levels.
Huasun claims 24.16% efficiency, 750 W output for heterojunction solar panel
The Chinese manufacturer said TÜV SÜD confirmed the results. It launched the G12 series of heterojunction solar modules, with a focus on utility-scale projects, in the second half of 2022.
Photovoltaics for biomethanation
Researchers in Denmark have studied the technical and economic feasibility of biomethanation through large-scale PV power generation. They said that the intermittent PV-driven biomethanation process matches the efficiency of continuous processes after several days.
Chinese PV Industry Brief: Industry group reports lower polysilicon prices
Polysilicon prices fell by as much as 2.10% in China this week, according to the China Nonferrous Metals Industry Association (CNMIA).
NREL presents new GaAs solar cell concept with 27% efficiency
The US Department of Energy’s National Renewable Energy Laboratory (NREL) has identified a low-cost way to produce high-efficiency III-V solar cells with dynamic hydride vapor phase epitaxy (D-HVPE). The synthesis involved a gallium arsenide (GaAs) solar cell with a gallium indium arsenide phosphide emitter layer.
Researchers shed light on mysterious, higher energy yields in vertical PV systems
Scientists in the Netherlands have sought to understand the reason for unexpected gains in vertical PV systems and found that these installations have a much higher heat transfer coefficient than their horizontally deployed counterparts.
Solar wafer prices could bottom out soon with new record lows
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.
PVEL upgrades solar module qualification testing
PV Evolution Labs (PVEL) says it has added new solar module qualification tests and fresh insights to improve intelligent module procurement strategies.
Perovskite-silicon tandem cell achieves 28.9% efficiency via high bandgap top perovskite cell
A group of international researchers has developed a new perovskite-silicon solar cell design using a top perovskite PV device with an energy bandgap of 1.67 eV and a new self-assembly monolayer based on carbazole. The tandem cell achieved a higher efficiency compared to counterparts without the monolayer and passed the IEC 61215 standard thermal cycling test.
