Korean scientists have fabricated a perovskite-organic solar cell with a sub-nanometer uniform dipole layer. During the tests, the device recorded an energy conversion efficiency of 24%, a new record for lead-based hybrid perovskite-organic solar cells. November 12, 2024 Patrick Jowett Researchers from the Korea Advanced Institute of Science and Technology (KAIST) and Yonsei University have fabricated an organic-inorganic hybrid solar cell with high efficiency and high stability. The research paper “Suppressing hole accumulation via sub-nanometer dipole interfaces in hybrid perovskite/organic solar cells to boost near-infrared photon collection”, available in the magazine Advanced materials, says that a major bottleneck toward efficiency…
Construction of the rooftop solar PV system started in January 2024. Image: Solvus. Farnborough Airport in Hampshire has completed a £2 million rooftop solar PV project courtesy of solar installer Solvus. With an installed capacity of 1,700 kWp, the system will be able to generate more than 1.2 GWh of sustainable energy per year and supply up to 25% of the airport’s annual electricity needs. The installation will also facilitate the airport’s growing fleet of electric vehicles (EVs) by providing green energy. Approximately 75% of annual solar energy generation will be used on-site, while the remaining 25% will be sold…
Scientists in the Middle East have developed a series active filter to improve power quality in grid-tied PV systems, consisting of an inductor, two capacitors and four transistor-diode pairs. The filter reduces the total harmonic distortion of voltage and current waves at the output of the inverter. November 12, 2024 Emiliano Bellini An Iraqi-Lebanese research team has proposed using a series active filter on the DC side of grid-connected PV systems to improve power quality. Active power filters are increasingly used in PV systems to simultaneously compensate for current harmonics and voltage unbalance. “The use of filters in systems has…
The global PV industry has grown tremendously in 2023, with unprecedented installation volumes reported throughout the year and even more expected for 2024, according to the “Trends in PV applications 2024report published by IEA-PVPS. Unprecedented PV installations and China’s dominant market China has led this expansion and has installed an astonishing amount of PV capacity to absorb the production surplus. Chinese installations alone account for more than 60% of global PV deployment, reflecting the country’s aggressive investments in renewable energy and its manufacturing capacity to meet both domestic and international demand. The report notes that while China is making progress,…
The new law aims to improve the efficiency and reliability of Jordan’s electricity infrastructure and introduces the concept of energy storage into the country’s legislation for the first time. November 12, 2024 Marija Maisch By ESS news Jordan has passed a new electricity law that replaces the 2002 temporary legislation and encourages investments in electricity storage and green hydrogen projects under the public-private partnership (PPP) model. Minister of Energy and Mineral Resources Saleh Kharabsheh has said that the main benefits that distinguish the new law from the previous temporary regulations include provisions for licensed entities involved in the transportation, generation…
An international research team has used data from Beijing’s public transportation system to investigate whether bus depots could house solar installations and energy storage facilities to help reduce the burden on the city’s grid. The researchers say they plan to generalize their proposed model to help other areas estimate the potential return on investment from transforming other civilian infrastructure into energy hubs. November 12, 2024 Patrick Jowett An international research team led by the University of Utah has explored the potential of installing on-site solar and energy storage at existing bus depots. The research is based on a case study…
Enphase Energy says it plans to restructure its operations, reduce its global workforce by 17% (approximately 500 employees and contractors) and close its contract manufacturing site in Mexico. November 11, 2024 Brian Public The bi-directional EV charger from Enphase Energy Image: Enphase Energy Enphase Energy has unveiled plans to cut 17% of its global workforce, affecting a total of around 500 employees and contractors, as part of a major restructuring. The company said in a statement to the U.S. Securities and Exchange Commission that it aims to align its operations and workforce with current business needs, focusing on cost reduction…
That figure would require incentives, regulation and ambition. A study by Clean Energy Latin America (CELA) estimates that Brazil’s storage market should grow at least 12.8% annually through 2040, reaching a cumulative 7.2 GW, excluding customer-side ‘behind the meter’ installations. November 11, 2024 Livia Neves By ESS news Brazilian consultant CELA has said that the inclusion of electrical energy storage systems in a federal government capacity reserve auction, which could take place in June 2025, could strengthen Brazil’s National Interconnected System (SIN) network. “By allowing the storage of renewable energy generated during times of lower demand, we will significantly reduce…
A Belgian-Dutch research group has designed a PV noise barrier that reportedly delivers good performance in terms of power output, driver safety and noise suppression. The payback period was estimated at six to ten years. November 11, 2024 Emiliano Bellini A Belgian-Dutch research team has developed a photovoltaic noise barrier with a ZigZag design for applications along (highway) roads, but also in facade applications of buildings. “Especially in densely populated areas, such as Eindhoven, space for PV installations is limited and living comfort in neighborhoods close to highways is under pressure,” says Fallon Colberts, lead author of the study. pv…
Agence Française de Développement has signed a ZAR 125 million ($7 million) grant agreement with South African utility Eskom to support the development of a hydro storage system project. November 11, 2024 Patrick Jowett Image: Filiz Elaerts, Unsplash French development agency Agence Française de Développement is investing ZAR 125 million in a hydro storage system project in South Africawhich will be developed by a state-owned company Eskom. The Tubatse Pumped Storage System project will be built in Elias Motsoaledi, Limpopo. It will have a power generation capacity of 1.5 GW, consisting of four 375 MW units, in addition to a…
