MIT researchers plan to use acenes to make singlet fission solar cells
Acenes are benzene molecules with unique optoelectronic properties. Singlet fission solar cells can produce two electrons from one photon, making the cell more efficient.
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.
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.
Monoprice unveils new PowerCache batteries with up to 1,000 W of output
Monoprice, a U.S. consumer electronics supplier, says its new portable batteries can store electricity from solar panels and wall outlets. They range in price from $199.99 to $799.99.
Ascent Solar announces 17.55% efficiency for CIGS tech
Ascent Solar, a US-based manufacturer, has achieved an efficiency of 17.55% for its copper, indium, gallium and selenide (CIGS) technology. It says it plans to release a new CIGS solar module with this efficiency rating soon.
MIT scientists develop concentrated solar power system to produce hydrogen
Massachusetts Institute of Technology (MIT) scientists have developed a train-like concentrated solar power (CSP) system for hydrogen production, with plans to build a prototype in the coming year. They say that this innovative system can capture up to 40% of the sun’s heat to produce environmentally friendly hydrogen fuel.
High resolution satellite imagery for residential PV system detection
Maxar Technologies used satellite imagery to identify rooftop PV systems in southern Germany. The company claims its new approach was able to identify 97.8% of the solar arrays with high confidence.
Heat pump design to reduce footprint of solar thermal installations
A U.S.-Mexican research team has investigated how linking heat pumps with solar thermal collectors may help reduce the surface needed to deploy the collectors themselves.
IEA-PVPS releases guide for applying innovation system approach to BIPV
IEA-PVPS has published a new handbook that provides support for Technological Innovation System (TIS) analysis for building-integrated photovoltaics (BIPV).
