Solar deployment and policies have had a mixed effect on electricity prices, researchers find
While large-scale solar and wind deployment “may have reduced” retail electricity prices over the past five years, net energy metering and renewable portfolio standards generally increased prices, the researchers found. But states with the highest renewable generation in 2024 had among the lowest prices.
Cadmium telluride vs. crystalline silicon in agrivoltaics
Canadian researchers investigated how the transparency of cadmium telluride and crystalline silicon solar panels affects lettuce growth in agrivoltaic systems. They found that 69%–transparent silicon panels increased lettuce yield by 3.6%, whereas cadmium telluride panels led to a reduction in yield.
NREL researchers address safety implications of next-generation battery technologies
Report says new evaluation methods, including AI, will help make future batteries safer.
IEA-PVPS warns soiling costs solar industry billions per year
The International Energy Agency’s Photovoltaic Power Systems Programme (IEA-PVPS) says dust, pollution, and debris on solar panels reduce output by 4% to 7% worldwide, costing the industry billions of euros annually and making tailored mitigation increasingly urgent.
Tiny pinholes can lead to device failure in perovskite solar cells
Researchers in the United States have found microscopic pinholes in perovskites are responsible for the breakdown of such solar cells when under reverse bias conditions. They say the findings should push scientists and engineers to prioritize the production of pinhole-free films to make perovskites more robust and stable.
Scientists boost organic solar cell efficiency using polymer zwitterions
A research team based in China and the United States has developed electroactive polymer zwitterions to modify zinc oxide interlayers in organic solar cells. Their work was found to passivate defects in organic solar cells, helping to improve device performance and stability.
NREL researchers warn of unexpectedly high UV-induced degradation in n-type solar modules
A research team from the U.S. National Renewable Energy Laboratory has analyzed n-type modules deployed in a 3 MW commercial PV project in an effort to assess the high degradation rate reported by the plant owner. The scientists found that ultraviolet-induced degradation (UVID) was a major factor affecting the facility’s performance.
All back-contact perovskite solar cell designs at a glance
Scientists from Japan, Saudi Arabia and the United States have investigated existing back-contact perovskite solar cell architectures and have proposed a strategy to help reach commercial production.
New hail test aims to more accurately measure solar panel resilience
A new test curve for determining solar panels’ breaking point from hail uses a broader spectrum of impact energies and testing products.
Finetuning 2D Dion-Jacobson perovskites for photovoltaic applications
Canadian and U.S. researchers have investigated applying pressure to a 2D hybrid organic-inorganic perovskite to tune the optical and electronic properties to suit photovoltaic applications, light emitting diodes or other semiconductor devices.
