EU cross-border solar auction largely oversubscribed
The first tender under the European Union’s new €40 million ($41.8 million) multilateral solar scheme – targeting 5 MW to 100 MW projects based in Finland and providing energy to Luxembourg – has been ‘oversubscribed’ with bids ‘significantly exceeding target volumes’, the European Commission’s Directorate-General for Energy recently announced.
US solar construction costs fell amid pandemic, says EIA
PV module prices have fallen since the start of the pandemic in 2020, reaching a global two-year low in April 2023, according to the US Energy Information Administration (EIA). In the first two months of this year, average PV module prices in the United States stood at $0.36/W (DC), down 11% on a quarterly basis.
Researchers build 20-μm-thin monocrystalline solar cell with 21.1% efficiency
The scientists built the device by depositing multiple metal nanofilms on both sides using plasma-enhanced chemical vapor deposition. The cell achieved an open-circuit voltage of 684 mV, a short-circuit current density of 38.2 mA/cm2 and a fill factor of 80.8%.
Europe’s largest CSP plant for self-consumption goes online in Spain
Heineken España and Engie España have commissioned a 30 MW concentrated solar power (CSP) plant in Seville, Spain, with 68 MWh of storage capacity, marking the inauguration of Europe’s largest concentrated solar power plant.
Agrivoltaic system design for olive cultivation
A research team in Spain has developed a PV system layout for super-intensive olive groves. The scientists said the system must ensure high levels of transparency in order to avoid a negative impact on the olive yield.
New model for day-ahead solar forecasting in areas with limited data
South Korean researchers have developed a long-term solar irradiance prediction method based on a reinforcement learning algorithm. They claim that the new model is able to forecast solar radiation for more than a year using just two weeks of solar radiation learning.
European research group creates injection molding plastic solar cells
A French-Spanish research team developed organic photovoltaic modules embedded into plastic parts through high throughput injection molding. The researchers injected thermoplastic polyurethane in the modules and found it enhances their mechanical stability while keeping a high flexibility.
Swedish startup to use green hydrogen plasma in pilot reactor for solar grade silicon
Encouraged by lab results and a feasibility study, Swedish startup, Green14, in collaboration with Sweden’s Royal Institute of Technology (KTH) plans to build a pilot-scale reactor to make solar grade silicon with a hydrogen plasma process. The company sees the pilot as a step towards using a more sustainable method to produce solar grade silicon for the PV industry at its own gigawatt-scale plant.
MIT scientists develop solar desalinator with high water output
Massachusetts Institute of Technology (MIT) researchers have developed a solar desalinator with high water output, via a multi-stage system of evaporators and condensers. It offers cost-effective solar desalination, making solar-produced drinking water cheaper than tap water for the first time.
Novel perovskite/CIGS tandem PV cell design promises 38.39% efficiency
A research team in Bangladesh has simulated a perovskite-CIGS PV device that can reportedly achieve a remarkable tandem cell voltage of 2.48 V. The proposed method is also applicable for tandem cells composed of other materials.
