A new method of creating an ordered mesh of nanowires, developed by scientists at the Lawrence Livermore National Laboratory in the United States, could lead to the creation of more efficient transparent electrode layers in solar cells – and the elimination of a rare material from the manufacturing process.

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.

Power purchase agreements for 8.6 GW of clean energy have been signed in 2019 till July—up from 7.2 GW at the same time last year—with USA alone accounting for up to 70% of the deals. India continues to lead the Asia Pacific region despite registering a slowdown in the activity.

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.

By considering use of the metal in charging infrastructure, analyst Wood Mackenzie has found higher demand from the mobility sector than is the case if only the volume of the material required for vehicle construction is examined.

Extreme wind events are the biggest cause of failure and insurance claims for any PV plant, according to Thorsten Kray, Head of the Building Aerodynamics Department at Institut für Industrieaerodynamik GmbH, Aachen. For structural reasons, single-axis trackers are more prone to the issues than fixed-tilt structures. In this two-part series, pv magazine will examine the ways that wind impacts trackers and what EPCs and investors need to look out for, in addition to outlining a range of approaches from big tracker suppliers that were designed to mitigate wind-related damage.

Few in the industry predicted the speed at which monocrystalline technology would develop, or the impressive cost reductions it would achieve by 2019. This has left producers of multicrystalline products facing rapidly shrinking market share and struggling to compete on a cost per watt basis. Many are now turning to cast mono processes, essentially creating a monocrystalline, or ‘mono-like’ silicon ingot in a multicrystalline furnace, to reach higher efficiencies and extend equipment lifetimes.

The Palo Alto company says it has improved its large scale battery offering with the new product in the wake of the success of its Powerpack-driven big battery in Australia. The Megapack can be deployed at a 250 MW/1 GWh clean energy plant four times faster than a fossil fuel alternative, claimed the business in a blogpost.

“Solar cells prefer to operate in a refrigerator,” says UNSW Professor Martin Green. His global research team is now identifying viable ways to cool down solar PV modules while amping up energy production to an unprecedented level.

If China could travel back to the 1960s with its 2016 PV generation capacity it could harvest an additional 14 TWh of solar power, according to a study by academics at universities in Switzerland and the Netherlands. With a mixed record for reducing pollution, the country’s solar fleet output appears to be drastically affected by dimmed solar radiation.
