Researchers in Nigeria have proposed building inverted perovskite solar cells exclusively with completely inorganic transport materials and a lead-free perovksite absorber. Through a series of simulations, they showed that this device can achieve an efficiency of more than 30% with low production costs. May 27, 2024 Emiliano BelliniA research group in Nigeria has proposed building n-type heterojunction planar inverted perovskite solar cells without using transparent conductive oxides (TCOs) for the passivation contacts.The researchers said this new design aims to maximize cell performance while reducing production costs and environmental impact. “The ability to achieve high efficiency using the reverse planar technique…
Swiss consultancy Pexapark says the total capacity of signed power purchase agreements (PPA) in Europe more than doubled in April compared to the volume in March. Meanwhile, all tracked PPA prices rose 1.6% month-on-month. May 27, 2024 Patrick Jowett European developers signed 28 PPAs in April for a total of 1.5 GW. according to the latest report of Pexapark. The total capacity has more than doubled compared to the amount registered by Pexapark Marchmaking April the second strongest month in terms of PPA activity this year.The second largest renewable energy deal was an onshore wind deal between Alterric and Statkraft,…
Affordable Wire Management (AWM) announced that the company has achieved a 630A rating Renewable Energy Test Center (RETC), a Nationally Recognized Testing Laboratory (NRTL). AWM’s CMS is the first in the industry to achieve this rating, making their offering eligible to support Sungrow’s recently released 4.4 MW SG4400UD-MV modular inverter in North America. “Sungrow’s 4.4 MW inverter breaks new ground for more efficient and cost-effective utility-scale solar design. By installing our inverters, developers can reduce overall LCOE by requiring fewer inverters per megawatt. Thanks to AWM’s innovations, the higher demands are managed safely, as their all-metal CMS are bonded and…
Solar mounting system manufacturer and balance-of-systems supplier Clenergy’s ezShade 2.0 solar shading system has been put to the test with the solution at the heart of a self-contained energy system serving an off-grid communications site in remote north Queensland supplies fuel. May 27, 2024 David Caroll By pv magazine AustraliaChinese-Australian company Clenergy said its standalone power system (SAPS) with 18 kW of solar energy coupled with 270 kWh of battery energy storage has been used by a mining company to provide autonomous power for its communications facilities in its North Queensland operations.The SAPS is centered around Clenergy’s PVezRack ezShade 2.0…
US scientists have developed a thermofovoltaic cell that can be combined with cheap thermal storage to provide power on demand. The indium gallium arsenide (InGaAs) thermofovoltaic cell absorbs most of the in-band radiation to generate electricity, while serving as a near-perfect mirror. May 27, 2024 Emiliano BelliniThermophotovoltaic energy (TPV) is a power generation technology that uses thermal radiation to generate electricity in photovoltaic cells. A TPV system typically consists of a thermal emitter that can reach high temperatures, close to or above 1000 C, and a photovoltaic diode cell that can absorb photons coming from the heat source.The technology has…
The second phase of Ireland’s Small-Scale Renewable Electricity Support Scheme (SRESS) targets local communities and small and medium-sized enterprises that produce their own electricity. May 27, 2024 Patrick JowettThe government of Ireland has announced the second phase of its SRESS. The latest phase focuses on community and local projects, or sustainable energy communities (REC). It also targets small and medium-sized enterprises (SMEs) that produce their own solar or wind energy, in addition to export-only projects of less than 1 MW.The scheme offers a guaranteed feed-in premium rate without an auction. Government guidelines says successful applicants will receive a premium on…

Research team reaches important milestone in solar cell efficiency A research team has created a tandem solar cell with antimony selenide as the bottom cell material and a hybrid perovskite material as the top cell, achieving an energy conversion efficiency of more than 20 percent. This advance highlights the potential of antimony selenide for soil cell applications. Photovoltaic technology converts sunlight into electricity, providing a clean energy source. Scientists aim to improve the efficiency of solar cells, reaching more than 20 percent in conventional single-junction cells. Exceeding the Shockley-Queisser limit in these cells would be costly, but tandem solar cells…
Christian Victor, an X (formerly Twitter) user, has published a new map showing land consumption in Germany. This shows that open-pit mines take up more square meters than ground-mounted solar panels and wind farms combined. May 23, 2024 Petra Hannen The visualization of land use brings some surprisesImage: Christian Victor, @cvictordusBy pv magazine GermanyA surprising map of Germany is currently circulating on the internet. The map, published by X (formerly Twitter) user Christian Victor, shows the country’s land consumption based on different types of surface use.In addition to large areas for livestock feed, forests and vegetable crops, there are many…
Entergy Louisiana’s proposal to add up to three gigawatts of economical solar to its generation portfolio has been approved by the Louisiana Public Service Commission, marking the largest expansion of renewable energy in the state’s history. “This approval underscores our commitment to meeting operational and sustainability needs, driving economic development and protecting the environment,” said Phillip May, president and CEO of Entergy Louisiana. “It is an important victory for the future of our state. I want to thank everyone who helped bring this proposal to fruition, including our local officials and regulators.” The approval allows for a streamlined procurement and…
