The new regulatory framework includes the option to sell electricity to large energy consumers through bilateral PPAs.
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.
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.
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.
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%.
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.
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.
