Researchers from Australia’s Monash University have created a new generation of lithium-sulfur batteries to provide a cheaper, cleaner and faster-charging energy storage solution that outlasts lithium-ion alternatives and is rechargeable hundreds of times without failing.

The London-based analyst has published a series of clean tech predictions for the year which also highlighted the rising proportion of sub-5MW solar projects in the global market, and cheaper clean energy financing costs even as panel prices continue to rise.

Researchers in Saudi Arabia have fabricated an integrated fully PV-powered system to extract fresh water from the atmosphere. The system uses excess heat from the solar modules to evaporate and condense water that can then be used to grow crops. Part of the water is also used to cool down the solar modules through an active cooling technique.

Megasol said the solar module relies on new back-contact technology that is able to reduce internal resistance, ohmic losses and cell spacing.

With 90% of world economies committed to net zero targets, the disruptive nature of the energy transition is becoming clear. Climate targets require us to triple renewable energy capacity by 2030, phase out coal by 2040, end fossil fuel subsidies, and ensure support for a just transition. While hydrogen is sure to be a key technology in this energy transition, the exact role it will play is not yet clear, reports Felicia Jackson.

Dutch company Rads Global Business has developed an anti-soiling coating for solar PV modules that are at least two years old. The new product is claimed to increase power yield by up to 7% and to have a payback time of 2.5 to four years depending on the dust level of the site.

Developed by Germany’s Fraunhofer ISE, the cell is manufactured with metallization based on a plating process. The device was built with galvanic nickel/copper/silver contacts instead of common silver contacts.

The tandem cell was fabricated by German scientists through a process flow that is compatible with industrial, mainstream PERC technologies. According to its creators, the device has the potential to exceed efficiencies of over 29% with adjustments in the perovskite thickness and bandgap.

Mass adoption of electric vehicles presents opportunities for significant battery deployment to support our grid and power our homes. Developing and adopting standards for vehicle-to-grid bidirectional technology is needed to accelerate the path to these opportunities, reports pv magazine USA’s Tim Sylvia.

Two industry experts have provided analyses of the current polysilicon price scenario in a chat with pv magazine and both agreed that polysilicon demand is still growing faster than supply. The price may decrease starting from the second quarter and reach more reasonable levels by the end of the year.
