Dubai’s tender for 6th phase of giant solar park attracts lowest bid of $0.0162154/kWh
DEWA said it will announce the preferred bidder for the 1,800 MW 6th phase of the Mohammed bin Rashid Al Maktoum Solar Park in the third quarter of this year.
Photovoltaic-thermal solar panel based on water storage tank
A research group from Ireland developed a PVT system consisting of a 170 W photovoltaic panel connected to a water tank placed at the backside of the PV module itself. The PVT module is able to considerably reduce the temperature of the PV unit while producing hot water for residential use.
PV-powered offgrid air conditioner for building applications
A British research team has investigated the technical feasibility of an air conditioning unit powered exclusively by solar-plus-storage and has found that two 130 Ah batteries charged by two 400 W solar panels are capable of supporting the system during the night.
Improving ground-mounted solar power plant performance via orbiting reflectors
Scientists in the United Kingdom have proposed using orbiting solar reflectors to enhance the electricity yield of terrestrial solar power plants. They claim this new technology may be particularly beneficial for improving generation at dusk and dawn, when irradiance is lower.
KAUST claims 33.7% efficiency for perovskite/silicon tandem solar cell
The European Solar Test Installation (ESTI) has confirmed the results of King Abdullah University of Science and Technology’s (KAUST) new perovskite/silicon tandem solar cell. The 1 cm2 device also achieved an open-circuit voltage of 1.974 V, a short-circuit current density of 20.99 mA/cm2, and a fill factor of 81.3%.
Novel approach to PV-battery-electrolyzer-fuel cell systems
TU Delft scientists have proposed a new methodology for off-grid PV-battery-electrolyzer-fuel cell systems in remote areas.
New perovskite solar cell design promises 31.09% efficiency
Chinese researchers have developed a solar cell using CsSnI3 perovskite, known for its unique phase transitions and near-IR emissions. By simulating the device with various electron transport layers (ETLs) and hole transport layers (HTLs), they determined that the optimal cell could be created using a titanium oxide (TiO2) ETL and a nickel(II) oxide (NiOx) HTL.
Sharp unveils 570 W TOPCon solar panel with 22.07% efficiency
Sharp’s new IEC61215- and IEC61730-certified solar panel offers a power conversion efficiency of 22.07% and a bifaciality of more than 80%. The operating temperature coefficient is -0.30% per C and its power tolerance is 5%.
Researchers assess degradation in PV systems older than 15 years
Scientists have used the US National Renewable Energy Laboratory’s (NREL) HOMER software to calculate the degradation of solar panels deployed in two rooftop PV systems operating in Germany since 2003. Their calculations focused on the energy productivity of the systems.
Tongwei led global polysilicon capacity in 2022, says Bernreuter Research
The world’s top four largest polysilicon producers in 2022 were Chinese companies, led by Tongwei with 345,000 metric tons (MT), followed by GCL Technology, Daqo, Xinte, and Wacker Chemie.
