Imec integrates silicon heterojunction solar cells into curved surfaces
Imec has successfully integrated silicon heterojunction PV cells into curved surfaces, resulting in a 6% efficiency increase compared to passivated emitter and rear contact half cells. The cells are suitable for applications in vehicle-integrated and building-integrated photovoltaics.
Photovoltaics for marine wildlife telemetry devices
A research team has tested mini solar modules in marine data collection devices, using animal hosts for water column profile measurements. The findings suggest that submarine PV can effectively operate in these applications at depths of up to 22 meters.
Study frames out EV charging network for the western National Park system
Assuming there are nearly 40 million EVs on the road by 2030, researchers suggest the region needs between 2,350 and 4,610 direct current fast charging ports.
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
