According to a U.S. research team, new nanomaterials relying on dyes based on diketopyrrolopyrrole and rylene can generate a singlet fission reaction that extends the life of harvestable electronic charges.
The Renewable Energy Project Development Office is tendering seven large-scale IPP solar projects. The exercise is part of Round 2 of the Saudi National Renewable program, which is expected to allocate almost 2.2 GW of PV capacity this year.
At the Korea-China Free Trade Agreement Joint Committee meeting, the South Korean government urged China to lift import measures against its polyoxymethylene, optical fiber, polysilicon and grain-oriented electrical steel. China imposed duties on polysilicon from South Korea and the United States in July 2013.
Taiwanese market research company EnergyTrend says the 5/31 policy change in China last year had a less dramatic effect on global demand than expected and, with the Modi government introducing solar-friendly policies, India – and Japan – will close the gap on the world leaders for installed PV capacity.
IRENA says technologies for 3D rooftop footprint generation and solar irradiation modelling are becoming increasingly cheap, making them suitable for deployment anywhere in the world. Developing cities could access such technical resources to plan rooftop PV development.
Researchers say the use of clustering-based computation could remove the need for on-site inspections of panels by instead enabling real-time monitoring of degradation using only meteorological data.
The research team was able to improve the cell efficiency by 2.1%. The cell silicon layer was etched on the back-side, while a a polymer light management (LM) foil was applied to the front-side of the device.
