Photo: DOE In the United States, energy demand is rising after decades of stagnant growth, driven by electrification efforts, data centers and artificial intelligence. As demand increases, the economy continues to favor wind and solar energy, which consistently rival gas and coal in terms of affordability. As rural communities look to increase renewable energy, a unique opportunity presents itself. Flat, sunny and easily accessible land that is ideal for solar parks is often already in use for agriculture. A new one report from the Institute for Energy Economics and Financial Analysis (IEEFA) highlights the opportunity to expand the use of…

Researchers in China have improved the performance and durability of inverted perovskite solar cells by creating two new 56pi electron fullerene derivatives, known as C60-TFB and C60-TFP, for use as electron transport layers. The research team synthesized C60-TFB and C60-TFP via a 1,4-asymmetric addition approach, giving the molecules bulky tert-butyl, indole and azaindole groups. These groups prevent dimerization when exposed to light and provide a strong bond with the perovskite layer, resulting in fewer defects. The resulting electron transport layer forms an effective barrier to stop the migration of iodide ions from the perovskite layer and silver atoms from the…

The Ihma Dam solar project is South Korea’s largest floating PV installation, located next to a multifunctional dam. The project has a resident participation model that allows those living within a radius of one kilometer to share the profits from the power supply. November 14, 2025 Patrick Jowett The Ihma Dam floating solar power plant with a capacity of 47.2 MW has been put into operation South Korea. Located at the Imha Dam east of Andong city in Gyeongsangbuk-do Province, the solar array is the largest floating PV installation located next to a multi-purpose dam in South Korea. The dam…

Leaders from more than 100 organizations in Pennsylvania were addressed a letter to the Pennsylvania Public Utility Commission demanding interconnection reforms for a greener and affordable grid. The supporting organizations, which represent Pennsylvania businesses, civic leaders and environmental groups, have a presence in communities affected by fossil fuels and rising energy prices. “They share the belief that the key to securing a resilient and affordable energy system in a time of economic unpredictability lies in adding more reliable and low-cost local distributed energy resources (DERs). This includes solar, wind and battery storage, as well as energy efficiency. However, this vision…

A team from the University of Arkansas and the University of Michigan has demonstrated the first use of temperature sensors powered solely by graphene-based solar cells, laying the foundation for battery-free sensor systems. Using graphene’s extraordinary energy harvesting ability, these devices can capture energy from their environment, including solar, thermal, acoustic and kinetic sources. The researchers built dozens of graphene-silicon solar cells and connected them in series to increase the voltage output. These were used to charge storage capacitors, allowing the sensors to operate independently for over 24 hours after just a few minutes of charging. The absence of conventional…

According to the latest analysis by the British consultancy GlobalData, the annual increase in solar energy in the Netherlands until 2035 will be between 4.5 and 5.5 GW. November 14, 2025 Patrick Jowett The Netherlands is on track to deploy 79.9 GW of solar energy by 2035, according to an analysis by London-based data analytics and consultancy firm Global data. GlobalData expects the Netherlands to add 4.7 GW of solar energy this year, bringing the cumulative capacity to 33.3 GW. The analysts then predict that approximately 5.4 GW of solar will be added in 2026, followed by annual additions of…

S-5!a supplier of solar and metal roof mountings, has developed a clamp for solar carport applications. The S-5-CP Clamp (CP for Carport) is designed to fit both “C” and “Z” purlin frame assemblies, using a non-penetrating attachment for solar applications. The design protects against corrosion by eliminating the need for drilled holes. S-5-CP clamp from S-5! “Carport solar is one of the fastest growing segments in mounting technology,” says Rob Haddock, S-5! CEO and founder. “The S-5-CP clamp allows engineers and installers to design stronger, simpler and more cost-effective solar carport systems using trusted S-5! technology.” The clamp can be…

Researchers have achieved a new level of control over the atomic structure of a family of materials known as halide perovskites, creating a finely tuned ‘energy sandwich’ that could transform the way solar cells, LEDs and lasers are made. Because of their remarkable ability to absorb and emit light, and because they are cheaper and can be configured to convert a greater portion of the solar spectrum into energy than silicon, perovskites have long been touted as a potential replacement for silicon in solar cells, LEDs and quantum technologies. However, their instability and durability have largely limited perovskite devices to…

This week, Women in Solar+ Europe gives the voice to Clémence Leclair, ESG Manager at the German Belectric. She says active listening, empathy and self-reflection are essential components of strong leadership within the renewable energy industry. “As research and development professionals already know well, there is rarely just one path to excellence. In fact, some of the most unconventional approaches can prove to be the most effective or innovative,” she says. November 14, 2025 Women in Solar+ Europe The solar energy industry is one of the most dynamic and rapidly evolving sectors worldwide. It requires not only technical expertise, but…

In a new weekly update for pv magazineOPIS, a Dow Jones company, provides a brief overview of the major price trends in the global PV industry. November 14, 2025 OPIS The Global Polysilicon Marker (GPM), the OPIS benchmark for polysilicon produced outside China, was valued this week at $18,319/kg, or $0.038/W, up 0.28% on a weekly basis. Global polysilicon prices rose slightly this week, supported by reports of rising spot order prices. Market participants attributed some of this increase to customers seeking secure sources of supply in response to ongoing uncertainties surrounding the U.S. Section 232 national security investigation into…
