Carbon nanotube gives batteries a boost

Scientists in the U.S. examined the use of different conductive filler materials in a lithium-ion battery electrode, finding that adding single walled carbon nanotubes to a nickel-cobalt-manganese cathode resulted in better electrical conductivity and higher rate capability for the overall battery. The results, according to the group, could provide new insights into design of high power, high energy battery electrodes.

Terawatt scale by 2050

In a new paper published in the journal of Renewable and Sustainable Energy, renowned PV scientist Pierre Verlinden examines the solar industry’s trajectory towards the 70 TW of installed capacity that will be needed by 2050, as the best choice for meeting climate targets set out in the 2015 Paris agreement. Silver consumption and recycling, according to Verlinden, will be the biggest challenges in the years to come, as well as ensuring balanced growth and avoiding a major installation rush in the years close to 2050.

Weekend read: Singapore solar walks the talk

Earlier this year, Singapore surpassed its 2020 target for 350 MW of installed PV, and has set itself a more ambitious goal of 2 GW for the coming decade. pv magazine recently spoke with Thomas Reindl, deputy CEO of the Solar Energy Research Institute of Singapore (SERIS) – and also the lead author of a 2020 update to the institute’s PV Roadmap for Singapore report – to catch up on the latest developments in the city-state’s PV market.

Heating up the heterojunction-LID discussion

Scientists led by the University of New South Wales have looked into the long-term degradation of silicon-heterojunction. Their findings suggest that illumination at high temperatures could actually improve cell efficiency, but also risks activating multiple light-induced degradation mechanisms if not carefully controlled.

Degradation and regeneration in polysilicon passivation layers

Scientists in Australia took a close look at the long-term performance of passivation layers in silicon solar cells, and discovered a surprising process of degradation and regeneration at work within the material. The results could have implications on the processes used in industrial scale solar cell production.

Understanding the fate of end-of-life modules

Scientists in India have taken a close look at the potential impact of growing volumes of PV waste, and have conducted surveys that suggest a lot more work is needed from manufacturers and policymakers to develop management systems for end-of-life PV products.

Throw another prawn on the battery

Scientists led by MIT have suggested chitin, a carbon and nitrogen-rich material made from waste shrimp shells, could produce sustainable electrodes for vanadium redox flow batteries and other energy storage technologies.

Australian scientists develop new transparent electrode material

Scientists in Australia have developed a new transparent conductive oxide which could be used in solar cells, smart windows and other applications. The material is indium free and recyclable, according to the researchers.

Another billion-dollar quarter for JinkoSolar

Despite the challenges to both the manufacturing and shipment of its products during the period, JinkoSolar today reported that it shipped 3.4 GW of modules in the first quarter of 2020, bringing its revenue for the quarter just over the billion dollar mark.

Carbon accounting for beginners

A new report from Rocky Mountain Institute in the U.S. explores the need for companies to disclose information about greenhouse gas emissions throughout their supply chains, and the most effective ways to do this whilst ensuring consistency and comparability of collected data across multiple industries.
