U.S.-made perovskite-silicon tandem solar modules could be produced at around $0.35/W
Techno-economic analysis conducted by NREL researchers has shown how perovskite-silicon tandem solar modules could currently hardly compete in cost with incumbent PV panels. Production costs for U.S.-made tandem products were found to range between $0.29/W and $0.42/W, with module efficiencies ranging from 25% to 30%.
Korean scientists build PV-powered supercapacitor with 35.5 Wh/kg energy density
Scientists in Korea have fabricated a solar-powered charging device that can reportedly achieve a power density of 2,555.6 W kg and an energy efficiency of 63%. The system uses nickel-based compounds to enhance the electrochemical performance of its electrodes.
UK-African consortium explores perovskite solar manufacturing potential in Africa
The UK’s University of Swansea is leading a consortium that aims to develop sustainable next-generation perovskite solar manufacturing in Nigeria, Rwanda, South Africa, and Kenya.
How to measure industry’s carbon footprint
The IEC has launched a new portfolio of carbon footprint verification services to help build trust and credibility in companies’ commitment to monitoring and reducing their emissions.
Phnix releases PV-ready heat pumps for commercial buildings
The Chinese manufacturer said the latest version of its Phnix HeatMaster heat pump series enables seamless integration with PV arrays. The systems have a coefficient of performance of up to 5 and can reach an outlet water temperature of 75 C.
Novel MPPT tech based on salp swarm, hill climbing algorithms
Researchers have suggested to use a hybrid version of the so-called salp swarm algorithm (SSA) algorithm for maximum power point tracking in PV systems operating under highly fluctuating environmental conditions. The novel method also integrates the hill climbing algorithm, which simulates the process of climbing a mountain and reportedly helps find the best possible solution to a given problem.
Vertical rooftop PV performs better than conventional rooftop solar under the snow
A case study analysis by Norway’s Over Easy Solar has found that vertical rooftop solar panels outperform conventional rooftop PV systems during snowy months. Energy yield was up to 30% higher in the winter months in Norway, according to the company.
New simulation tool maps existing, planned district heating networks
Researchers in Germany have developed a simulation software tool that visualizes heat flows in existing district heating networks and is capable of predicting load peaks. It can also be used to help plan and commission new grids.
GCL SI enters back contact business with 660 W solar module
Chinese module maker GCL SI has expanded into back contact (BC) solar cell production with its first 660 W BC module, featuring tunnel oxide passivated contact (TOPCon) technology.
The impact of wildfires on PV power generation
Scientists have quantified the impact of wildfires on the availability of direct normal irradiance and global horizontal irradiance at the state, regional, and national levels in the United States. They have found that direct irradiance is more sensitive to smoke than the PV-relevant global horizontal irradiance.
