Fraunhofer ISE develops propane heat pump using only 146 g of refrigerant
Researchers at Germany’s Fraunhofer ISE have developed an optimized heat pump propane refrigeration circuit for single-family homes.
Keep your solar cells dry
Scientists in Norway used various imaging and characterization techniques to analyze the cells and other components of silicon PV modules that had been installed in the field for more than 10 years. The group’s aim was to isolate the role of moisture in various mechanisms that cause performance loss over time, and to understand how these mechanisms progress over long-term installation in real outdoor conditions.
The Hydrogen Stream: Hydrogen market to surpass LNG by 2030, says Deloitte
Deloitte says it expects steady hydrogen market growth, with annual revenue projected to hit $1.4 trillion by 2050, while Denmark and the Netherlands have started discussing hydrogen collaboration with the governments of Namibia, South Africa, and Morocco.
IEA-PVPS releases global benchmark for solar irradiance data
IEA-PVPS has published a report to help the solar industry to choose appropriate surface radiation models and data providers based on location and application requirements.
Rooftop PV system design to improve yield under partial shading
Scientists in India have proposed a new concept that improves the yield of rooftop PV systems under partial shading. This concept combines conventional total cross-tied (TCT) techniques with partial power processing converters (PPPCs), using a resonant switched capacitor converter (RSC) and a switch inductor converter (SLC).
Triple cation perovskite PV cell with ETL based on tin(IV) oxide hits 17.1% efficiency
Qatari researchers have incorporated an electron transport layer (ETL) made of tin(IV) oxide into a perovskite solar cell through air-thermal-annealing, resulting in better efficiency and stability. The device demonstrated an open-circuit voltage of 1.045 V, a short-circuit current of 22.01 mA/cm2, and a fill factor of 74.3%.
What might UK solar expect from a change in government?
Chris Sparkes, lead technician at UK solar installer Solar Fast tells pv magazine simply throwing money at the PV industry will not suffice.
Sunova Solar releases 605 W TOPCon solar panel with 22.9% efficiency
Sunova Solar is offering five versions of its new bifacial dual glass solar panels, with power outputs ranging from 585 W to 605 W and efficiencies of 22.1% to 22.9%. They feature 144 n-type monocrystalline TOPCon solar cells.
SolarEdge, SolarGik launch tracker solution for agrivoltaics
SolarEdge and Israeli startup SolarGik have developed a new solar tracker system for agrivoltaics. It includes a mounting structure, inverters, power optimizers, trackers, and a monitoring platform.
Temperature coefficient of short circuit current may not be proper metric for perovskite-silicon tandem solar cells
Researchers in Saudi Arabia have conducted a series of tests to investigate the temperature coefficient of the short circuit current in perovskite-silicon tandem solar cells and have found that it may not be considered a proper metric to assess these devices’ performance and behavior.
