A vision of a decentralized, renewable-powered electricity grid is being brought a step closer by scientists at the U.S. National Renewable Energy Laboratory. Their project, Autonomous Energy Grids, aims to take an overarching look at the solutions that will power this grid of the future, and to fill any gaps that appear between them.

To develop cost-competitive solar modules the nation must adopt a phased program and set up 15 GW of silicon-ingot-to-solar-module manufacturing capacity by 2024, according to The Energy and Resources Institute.

Scientists at the Australia National University have observed a key stage in the process of photosynthesis which could be copied to greatly increase the efficiency of sunlight-powered water splitting processes used to produce hydrogen.

The $500k order follows the delivery of two high-volume quantum-dot production systems—valued at $1 million—to support roll-to-roll printing of thin-film solar cells at Assam facility.

With India losing major solar markets to stiffer competition from cheaper products, it’s high time to change the game by playing on quality and innovation—according to Vikram Solar Chief Financial Officer Rajendra Kumar Parakh, who spoke to pv magazine on the challenge of shrinking markets before Indian solar manufacturers.

The new budget aims to seize the opportunity in energy storage and EVs through a range of incentives. However, alongside demand, production and export, the government also needs to focus on e-waste management and Li-ion battery recycling to sustain raw material supply and minimize environmental impact.

There is a sense in the PV cell and module market at the mid stage of 2019 that the push towards high-efficiency cell architectures is accelerating. This makes the case for half-cut cells in a module more compelling, and the quality of the cut edge vital – argue laser process suppliers.

Following the Indian government’s 40 GW plan for the states, Telangana has pitched for setting up a 5 GW lithium ion plant by announcing the ready availability of 200 acres of land and power and water for the fab at a concessional rate.

Pitched as a solution between dual-axis and single-axis trackers, the 2-axis solar tracker offers a yield increase comparable with dual-axis trackers at a significantly lower cost.

A team of researchers from Manchester University claims to have identified the dominant process causing light-induced degradation in silicon solar cells. The process, termed “trap-assisted auger recombination”, arises from a defect in the bulk of the silicon material which lies dormant until exposed to sunlight.
