Mozambique's largest pre-paid solar mini-grid

Mozambique's largest pre-paid solar mini-grid

Feb 6, 2018 Mozambique
The solar mini-grid will be the country's first privately developed and financed mini-grid, and is expected to generate up to 200kWp of solar power that will electrify the island's households, public institutions, commercial enterprises and water pumps.
Recycling and reusing worn cathodes to make new lithium ion batteries

Recycling and reusing worn cathodes to make new lithium ion batteries

Feb 6, 2018 United States
Nanoengineers at the University of California San Diego have developed an energy-efficient recycling process that restores used cathodes from spent lithium ion batteries and makes them work just as good as new. The process involves harvesting the degraded cathode particles from a used battery and then boiling and heat treating them. Researchers built new batteries using the regenerated cathodes. Charge storage capacity, charging time and battery…

Sun Shines on CIGS Photovoltaics

Sun Shines on CIGS Photovoltaics

Feb 5, 2018 Worldwide
Copper indium gallium diselenide CIGS photovoltaics has been around for a long time even in bendable form. It is intermediate in efficiency between organic photovoltaics - poor - and gallium arsenide PV - excellent. Both of those are available in more flexible forms. Dye Sensitised Solar Cells are nearer to CIGS in efficiency but their most promising form is perovskite.
A simple new approach to plastic solar cells

A simple new approach to plastic solar cells

Feb 5, 2018 Japan
Plastic solar cells, based on blends of conducting organic polymers, are of interest for making lightweight and cheap solar cells. The problem with these kinds of solar cells is that their solar power efficiencies are very closely related to the way the different types of materials mix and crystalize in thin films. This means complex and careful processing is usually needed to make efficient polymer solar cells.
