Infinite Turbine debuts heat pump turbine for homes, businesses
Infinite Turbine has developed a heat pump turbine for residential and commercial applications, using PV or alternative electricity sources for simultaneous cooling and hydraulic power. The tech can be retrofitted with existing CO2 heat pump systems for air conditioning, hot water, and process heat.
Inverted perovskite solar cell achieves 25.1% efficiency via new passivation technique
A group of scientists in the United States has utilized a new passivation strategy based on sulfur-modified methylthio molecules to build an inverted perovskite solar cell with a certified efficiency of 25.1% and remarkable stability. The proposed passivation approach reportedly led to a five-fold increase in carrier lifetime and a three-fold reduction in photoluminescence quantum yield losses.
Monitoring software may increase New York State’s grid capacity
Sustainable energy company Avangrid Inc. announced a pilot project with LineVision Inc. that explores increasing New York’s current transmission capacity through monitoring software.
U.S. Energy Information Administration says solar power will surpass hydropower by 14% next year
The rapid growth in the generation capacity of solar systems and decreased manufacturing costs can be attributed to this finding.
Gallium arsenide solar cell achieves 23.1% efficiency via electrochemical porosification
An international research group has utilized a new porosification technique to build gallium arsenide (GaAs) solar cells that allow the recovery of germanium films. The new cell achieved an efficiency that is reportedly in line with that of other GaAs PV devices, but can be produced at a lower cost thanks to the reuse of germanium.
New MPPT approach for multi-string PV systems under partial shading
Egyptian researchers have developed a multi-string PV system with a converter control strategy, achieving 99.81% efficiency with a direct duty cycle for maximum power point tracking (MPPT).
Using air conditioning to cool down PV modules, dry dishes
An international research team has investigated how air conditioning may be used to reduce the operating temperature of PV panels. The researchers not only found that the proposed approach is technically viable, but they also tested the use of excess heat from the panels for drying dishes.
Reconductor existing transmission to “unlock” renewables, says UC Berkeley study
Large-scale reconductoring of existing transmission lines could cost-effectively double transmission capacity within existing rights-of-way, a study says. Renewable energy projects near reconductored transmission lines could more easily interconnect.
Watch: Robots install solar project in Arizona desert
In its first commercial project, Terabase Energy successfully installed 17 MW of a 225 MW solar facility with its automated Terafab platform.
Mysterious, higher energy yields in vertical PV systems
Scientists in the Netherlands have sought to understand the reason for unexpected gains in vertical PV systems and found that these installations have a much higher heat transfer coefficient than their horizontally deployed counterparts.
