New tech may bring heterojunction solar cells based on p-type wafers closer to mass production
An Australian-Russian research group has developed a silicon heterojunction solar cell based on p-type gallium-doped wafers with an efficiency of 22.6% and an improved stability. The scientists are convinced that these wafers may become a mainstream solution for the SHJ segment within the next decade.
Australian utility tests compressed air storage
Compressed air energy storage is not exactly a new technology, but recent months have seen it get a new lease on life, as intermittent renewable sources of energy come to the fore.
Mondragon Assembly launches new interconnection equipment for solar modules
The new machine is claimed to be suitable for the production of all kinds of PV module technologies currently available on the market.
Hold your breath for a better battery
Recent research has revealed a previously underestimated role for oxygen in limiting the performance of lithium-ion batteries. Newly published research from both Japan and the United States has sought to look deeper into the chemical reactions at the heart of lithium-ion storage; and to better characterize the cumulative effects that minuscule amounts of oxygen released during these reactions can have on battery performance and safety.
Testing field for PV noise barriers
Two testing facilities for photovoltaic noise barriers are being built by a Belgian consortium. Their creators want to assess different PV technologies, reduce costs and plan large scale projects in Belgium, where land and policy constraints make the construction of ground-mounted PV plants almost impossible.
German start-up offers 5.2 kWh AC battery that works without inverter
Sax Power has developed a new residential battery which it describes as a game-changer in the battery technology.
Solar module for floating PV from Hyundai
The bifacial panel has a power output of up to 485 W and an efficiency of up to 21%. It relies on a transparent backsheet and is encapsulated with polyolefin elastomer (POE).
Serial inventor aims to change PV value chain by addressing heat
Kent Kernahan has set out to take the heat out of solar cells. He and his partners may end up bringing solar manufacturing jobs to disadvantaged communities, while making low-cost rooftop solar more widely available.
Maxeon adds another PV module to AC series
Singapore-based solar manufacturer Maxeon has unveiled the new Performance 3 AC panel, the latest addition to its AC range.
The Hydrogen Stream: What the EU’s Fit for 55 means for hydrogen
The revision of the EU Energy Taxation Directive (ETD) and the Renewable Energy Directive (RED) will also have an impact on the nascent hydrogen economy. The European Commission is currently evaluating options to create a certification system for low-carbon fuels and it may extend the EU-wide certification for renewable fuels to include hydrogen.
