Quantum dot hybrid HTJ cell with 12.82% efficiency
South Korean researchers have developed a hybrid tandem solar cell based on quantum dots and organic bulk heterojunction (BHJ) photoactive materials. They claim that the cell could reach an efficiency rate of around 15% if they continue to reduce energy losses in the quantum dot cell and enhance near-infrared absorption.
Integrating stress and temperature sensors in crystalline silicon cells
Fraunhofer ISE researchers have integrated stress and temperature sensors within a PV module. They claim that the devices cover a very minimal part of the cells, and that their interaction with the module and the cell itself is quite limited. The sensors can be manufactured as part of a regular cell manufacturing process.
Juwi applies new coating to operations and maintenance portfolio
The developer of the material, US-based specialist Pellucere, says its innovation can raise PV energy yield 3.5-4.2%.
Trina unveils two 500 W bifacial solar modules
The Duomax V and Tallmax V panels are equipped with glass-glass and glass-backsheet frames, respectively. Both offer a reported 21% efficiency and orders will be taken from the second quarter on. Trina plans to have a combined 5 GW of annual production capacity for the products this year.
International consortium claims 25% efficiency for perovskite CIGS solar cell
Researchers led by Belgian institute imec claim to have achieved the result with a 1cm² perovskite tandem solar cell. The result tops the 24.6% efficiency the consortium announced in September 2018. The cell’s developers are now aiming for 30%.
Why go solar? We can think of at least 333 reasons
Australian researchers have compiled data from 173 studies which examined homeowner behavior when buying rooftop PV and identified 333 predictors related to the attitude, knowledge, tendency, awareness, willingness and intent of householders.
Wireless sensing for remote operation of off-grid tracker solar
Researchers in Thailand are proposing a wireless monitoring solution for PV in remote locations. The system, based on global standard ZigBee 2.4 GHz wireless technology, can read data and tilt solar panels in auto and manual modes.
Slovakia launches first renewables auction
The ceiling price for solar and wind power has been set at €84.98/MWh. It is expected around 30 MW of generation capacity will be allocated and solar projects ranging in size from 100 kW to 2 MW will be entitled to participate.
Agrivoltaics in New Caledonia
The 16-greenhouse Focola project has been developed by French renewables developer Akuo and local utility company Enercal Energies Nouvelles on the Pacific Ocean territory.
A new residential inverter with battery interface from Growatt
The inverters of the TL-XH series have efficiencies ranging from 98.2% to 98.4%. The 10.8 kg devices are compatible with double-glass modules and higher yields, the manufacturer claims.
