The DGIST team sheds light on mechanisms that improve the efficiency of thin-film solar cells Researchers from the Daegu Gyeongbuk Institute of Science and Technology (DGIST), in collaboration with academics from Ewha Womans University, Incheon National University and MIT, have made significant progress in understanding the separation of electrons and holes in kesterite thin-film solar cells. This discovery is poised to improve the efficiency of solar cells and support the transition to sustainable energy sources. Solar cells convert sunlight into electricity and are seen as essential for future energy solutions due to their environmental benefits and unlimited resource: the sun.…
A research group in China has tested how membrane-based floating PV platforms can work in off-grid scenarios. Their analysis showed that, especially at high wave frequencies, these types of floating PV installations may suffer from the bending stiffness of the floater, which could limit both the in-plane and out-of-plane movement amplitude. May 13, 2024 Emiliano BelliniA team of scientists from Shanghai Jiao Tong University in China has assessed the wave and mechanical stress resistance of a membrane-based floating photovoltaic platform for applications in offshore waters.“Our work could provide, for the first time, a powerful and efficient numerical method for evaluating…
The International Islamic Trade Finance Corporation (ITFC), a member of the Islamic Development Bank (IsDB) Group, has signed a Memorandum of Understanding with the Regional Voluntary Carbon Market Company (RVCMC), aimed at assisting the Republic of Maldives in achieving its sustainability goals and tackling the consequences of climate change.Source: supplied. Scary. Hani Salem Sonbol, CEO of ITFC and Riham ElGizy, CEO of RVCMC.The project aims to assess the potential and feasibility of generating Blue Carbon Credits from the Maldives coastal ecosystem (mangrove forests and seagrass meadows) and to facilitate the sale of generated credits to carbon markets.This agreement was signed…
An exploratory study into the barriers to residential PV installations in South Africa reveals that no studies have examined how income influences the likelihood of households adopting rooftop solar. The researchers argue that this is “a glaring omission given the debates on just transitions.” May 13, 2024 Patrick JowettA team of researchers has called for a collective response from government and the private sector to address the barriers to residential solar adoption in South Africa.In “Adoption of solar PV systems on residential roofs in South Africa: an exploratory review of barriers”, which was recently published in the latest issue of…
Indian scientists have designed an off-grid energy system that relies on solar panels, lithium-ion batteries and Ćuk converters. The converters are the crucial components that enable the system to deal with varying input voltage due to changing sunlight conditions. May 13, 2024 Emiliano BelliniA group of researchers led by India’s Sardar Vallabhbhai National Institute of Technology has designed a standalone solar-plus-storage system for use in charging battery-powered road vehicles.“The system is based on an advanced battery charge monitoring algorithm with positive pulse current (PPC),” said the study’s corresponding author, Ashish K. Panchal. pv magazine, adding that it relies on PV…

It features improved vapor injection technology and uses A2L as a refrigerant. May 13, 2024 Emiliano BelliniUS-based heating specialist Midea has developed a new central duct outdoor heat pump for residential applications.“This latest generation of the Evox series, with the Evox G3 Heat pump and Evox G3 Air Handling Unit (AHU) represents the future of electric, inverter heat pump technology as a solution for home heating and cooling upgrades, designed to deliver unparalleled heating/cooling comfort,…
Researchers at Argonne National Laboratory have concluded that renewable energy could partially replace diesel fuel to power instruments and provide heat at the South Pole. They have proposed a hybrid solar, wind and energy storage that could reduce diesel consumption by 95% and save approximately $57 million over 15 years, after an initial investment of $9.7 million. May 13, 2024 Patrick JowettScientists from Argonne National Laboratory and the U.S. Department of Energy’s (DOE) National Renewable Energy Laboratory (NREL) have investigated the feasibility of using renewable energy to power the Amundsen-Scott South Pole Station in Antarctica.The facility, where climate change and…
Major progress in the sustainable production of syngas using solar energy Researchers from Shanghai Jiao Tong University have developed a new photocatalyst, Rh/InGaN1-xOx, that uses solar energy to efficiently convert greenhouse gases into syngas. This nanoarchitecture combines rhodium nanoparticles with oxygen-modified indium-gallium nitride nanowires, showing a syngas evolution rate of 180.9 mmol gcat-1 h-1 and a selectivity of 96.3%. This method offers a major improvement over traditional catalytic processes, which are energy intensive and can be quickly deactivated. “Our work represents a major step forward in addressing the dual challenges of greenhouse gas emissions and renewable energy production,” said Prof.…

A view of the Kasigau Ranch in Voi Sub County, Taita-Taveta County. [File, Standard] Chaos broke out at Kasigau Ranching Company’s annual general meeting (AGM) after shareholders clashed with the board of directors over the manner in which millions of shillings were spent. During the accused meeting, marked by heavy police presence, the over 3,750 shareholders rejected the reports of the company auditors and secretaries, calling them biased and inappropriate. Kasigau commander Benard Otomei and his officers stood guard as shareholders and directors made accusations about the spending of money at the ranch, which they said was facing a financial…
