Lead-free inverted perovskite solar cells without transparent conducting oxides may achieve 30% efficiency
Researchers in Nigeria have proposed to build inverted perovskite solar cells exclusively with all-inorganic transport materials and a lead-free perovksite absorber. Through a series of simulations, they showed these device may achieve efficiencies over 30% with low production costs.
Pexapark says European developers signed 28 PPAs for 1.5 GW in April
Swiss consulting firm Pexapark says the total capacity of signed power purchase agreements (PPA) in Europe in April more than doubled the volume it recorded in March. Meanwhile, all tracked PPA prices rose 1.6% month on month.
Construction begins on Sweden’s largest rooftop PV system
Brion Solenergi has started working on the Nordic region’s biggest rooftop solar project. The 14 MW array will span the rooftop of a warehouse owned by Danish transport company DSV.
Chinese scientists apply new models for sustainable wind, solar investments in Belt and Road Initiative countries
To assess renewable energy, particularly solar and wind, considering the limited supply of input materials, researchers from Shenzhen University established novel hybrid multi-criteria decision-making (MCDM) models that include a circular economy principles, waste potential and life cycle assessment (LCA).
Eurasian Development Bank to finance 300 MW of solar in Kyrgyzstan
The Eurasian Development Bank has agreed to provide $210 million over 15 years for Bishkek Solar to build a 300 MW solar plant in Kyrgyzstan. National Electric Grid of Kyrgyzstan will purchase the electricity for a period of 25 years.
Tender opens for 15 MW ground-mounted solar plant in Uganda
Companies interested in a new engineering, procurement and construction (EPC) contract for a 15 MW ground-mounted solar plant in western Uganda must request prequalification questionnaires from TotalEnergies Uganda by June 7.
U.S. scientists develop air-bridge thermophotovoltaic cells with 44% efficiency
U.S. scientists have developed a thermophotovoltaic cell that could be paired with inexpensive thermal storage to provide power on demand. The indium gallium arsenide (InGaAs) thermophotovoltaic cell absorbs most of the in-band radiation to generate electricity, while serving as a nearly perfect mirror.
India set to install 21.2 GW of solar in fiscal 2025
JMK Research projects that 21.2 GW of new solar capacity will be installed in India in fiscal 2025. The new additions will include 16.5 GW of utility-scale PV, 4 GW of rooftop solar, and 700 MW of off-grid installations.
Ireland opens fixed tariff scheme for small-scale solar projects
The second phase of Ireland’s Small-Scale Renewable Electricity Support Scheme (SRESS) is aimed at local communities and small- and medium-sized enterprises that produce their own electricity.
Car park solar roofing system for off-grid solution
The versatility of solar mounting manufacturer and balance-of-system provider Clenergy’s ezShade 2.0 solar shade system has been put to the test with the solution at the core of a standalone power system fuelling an off-grid communications site in remote northern Queensland.
