New research sheds light on intrinsic limitations of selenium solar cells
Danish researchers have analyzed fundamental material properties of selenium solar cells and have found their potential is higher than generally believed. They used carrier-resolved photo-Hall analysis to address discrepancies and reproduce experimental current-voltage and external quantum efficiency measurements.
InfinityPV unveils slot die coater for thin-film PV research
The customizable, compact sheet coater supports coating speeds from 1.2 mm/sec up to 33 mm/sec.
The Hydrogen Stream: Trafigura drops $471 million green H2 plan in Australia
Trafigura says it has scrapped plans for a $471.2 million green hydrogen plant in Australia after a feasibility study, while Aurora Energy Research says Germany, Spain, Sweden, and Great Britain could drive over 50% of renewable energy demand by 2035, requiring €100 billion in investment.
Sulzer, Hyme Energy to commercialize novel molten salt energy storage
Sulzer is developing advanced pumps for Hyme Energy’s patented molten hydroxide salt energy storage technology. Building on the success of the pioneering Molten Salts Storage (MOSS) project in Denmark, the partners now seek to commercilize the solution.
Transparent tandem solar cell hits record 12.3% efficiency
A global research team has developed a tandem solar cell with 30% transparency by combining perovskite and organic layers, achieving a record 12.3% efficiency for transparent solar cells.
Ultra-short-term PV forecasting based on convolutional neural network, long short-term memory
Scientists have created a novel probabilistic model for 5-minutes ahead PV power forecasting. The method combines a convolutional neural network with bidirectional long short-term memory, attention mechanism, and natural gradient boosting.
Denmark launches digital approval system for heat pump subsidies
Denmark has launched a digital approval system to automate most applications for its heat pump subsidy program. The system streamlines the grant process, which offers up to DKK 27,000 ($3,930) for qualifying heat pumps.
The Hydrogen Stream: US researchers link H2 impact to production
US researchers say hydrogen’s climate impact depends primarily on production methods and feedstock emissions, while Nikola Corp. has recalled 95 hydrogen-powered trucks and filed for Chapter 11 bankruptcy.
The Hydrogen Stream: MENA H2 projects surge in 2024
Dii Desert Energy says hydrogen projects in the Middle East and North Africa (MENA) surged to 117 installations in 2024, with 90% classified as green, while Plug Power has introduced the first-ever spot pricing program for liquid green hydrogen.
Denmark launches online tool for rooftop PV potential
The Danish Energy Agency has developed an online tool to assess rooftop solar potential, using laser scan data and building registrar information. The solution does not assess the economics of projects.
