A Chinese research team modified the absorber of a conventional perovskite solar cell with potassium trifluoromethanesulfonate (KTFS) and found that the additive improved the device’s performance and stability. The cell perovskite film reportedly showed fewer lead defects and lower JV hysteresis. June 6, 2024 Emiliano BelliniResearchers from Hangzhou Dianzi University in China have fabricated a perovskite solar cell using a multifunctional additive known as potassium trifluoromethanesulfonate (KTFS), which they claim can significantly reduce lead vacancy in the perovskite film.“The KTFS molecule is a typical type of potassium salt, including the cationic potassium (K+) and anionic trifluoromethanesulfonate (SO3C.F3−), indicating a bifunctional…
Livoltek says it has invested $13.2 million in a new inverter factory in Brazil. The facility will also soon produce lithium-ion batteries and chargers for electric vehicles. June 6, 2024 Alessandra Neris By pv magazine BrazilLivoltek, a PV inverter manufacturer and part of China’s Hexing Group, has unveiled details of a plan to build an inverter factory in the Manaus Free Trade Zone (AM), Brazil.The company said pv magazine Brazil that the factory will cover an area of 30,000 m2 and will require an investment of BRL 70 million ($13.2 million). in the first phase. The company’s plans also include…
The Lawrence Berkeley National Laboratory says the benefits of lower emissions are greater than most previous estimates. June 6, 2024 Michael PuttréBy pv magazine USAResearchers at Lawrence Berkeley National Laboratory have developed a new methodology for estimating the value of the climate and air quality benefits of wind and solar energy. A report detailing the results of an analysis of data from 2019 to 2022 using the methodology concludes that wind and solar energy generation delivered $249 billion in climate and air quality health benefits over that period.Renewable energy advocates claim that the leveled electricity costs (LCOE) does not tell…
As renewable energy becomes more accessible, an increasing number of Colorado Springs homeowners are considering installing solar panels. But before installing solar panels, conducting a solar site survey is a crucial step that should not be overlooked.
In recent years, awareness of climate change has grown dramatically, pushing more and more individuals and companies to be proactive. Although the sentiment is there, not many people know where to start as there is a lack of sustainable, effective and accessible solutions. Another problem, highlighted by Henry Albrecht, co-founder of TransaparenCis the general distrust in carbon projects, which prevents investors from supporting environmental initiatives on the scale required.Many people who are not well versed in carbon markets believe that carbon credits are often green-washed, and do not trust companies’ carbon claims. The dire lack of confidence often stems from…
UK-based Hive Energy said the projects will feature battery energy storage systems equivalent to 10% of total solar capacity. June 6, 2024 Patrick Jowett Image: Mariana Proença/UnsplashBritish developer of sustainable energy Hive energy has secured the grid connections for four projects in Serbia a total of 216.5 MW.The developer says two of the projects, 50 MW Pirot and 40 MW Prokuplje, are expected to pass the urban planning procedure and receive site conditions for PV and grid this summer. They will be followed by the Veliko Gradiste I and II projects, of 71.5 MW and 55 MW respectively, which Hive…
Atlas reveals the potential of solar energy in Germany Which roofs are suitable for solar panel installations? Where have photovoltaic systems already been installed? How much return can be achieved with solar panels at specific locations? A map developed by the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) provides the answers. The DLR researchers used machine learning methods to process current aerial photographs and geodata, allowing them to determine the solar energy potential for the entire stock in Germany of approximately 20 million buildings. The results for the entire country are publicly available at eosolar.dlr.de. The Solar…
Leapton says its new panels have a temperature coefficient of -0.30% per C and an efficiency of up to 23.14%. They come with a 30-year performance guarantee for 87.4% of the initial yield. June 5, 2024 Emiliano BelliniJapan-based Leapton Energy Co., Ltd. has released a new double-glazed solar panel based on n-type tunnel oxide passivated contact (TOPcon) technology and rectangular wafers.The LP182*210M66NB modules feature 182mm x 210mm n-type TOPCon cells and an aluminum alloy frame.“The modules are based on 210R cells, which offer the advantage of low open-circuit voltage, resulting in higher string power,” a company spokesperson said. pv magazine.…
From Sunlight to Savings Solar energy originating from the sun’s rays stands as a pivotal solution in addressing concerns surrounding resource scarcity and environmental harm. The growing emphasis on sustainability emphasizes the role of solar panels in environmental degradation. By converting sunlight into electricity, solar panels offer a renewable alternative to conventional energy sources, reducing reliance on finite resources and lessening environmental impact. Exploring the potential of solar panels becomes key in our pursuit of resource conservation and environmental sustainability. Understanding Solar Energy Solar energy refers to the light and heat emitted by the sun, which holds potential as a…
New research from India shows the benefits of deploying fixed-tilt, low-angle PV systems in regions with high summer load demand, such as India. The scientists said that while PV systems with low tilt angles may not achieve maximum energy yield or lowest levelized cost of energy (LCOE), they can reduce dependence on expensive electricity grids during periods of high demand. June 5, 2024 Emiliano BelliniA group of scientists from the Indian Institute of Technology Kharagpur have developed a new model for optimal PV installation angles in regions with high summer load demand, such as India, and found that low tilt…
