Organic solar cell gains counterintuitive efficiency boost from entropy
A research team at the University of Kansas have found that organic semiconductors known as non-fullerene acceptors demonstrate a high solar cell efficiency due to a reversed heat flow.
Indosolar starts production at 1.3 GW solar module factory
Indosolar, a subsidiary of Waaree Energies, has started production at its new 1.3 GW solar module manufacturing facility in India.
IEA-PVPS identifies 456 patents in PV module recycling
The IEA Photovoltaic Power Systems Programme’s (IEA-PVPS) latest report on solar panel recycling offers a comprehensive review of all existing technologies in this market segment, from pure mechanical recycling to innovative techniques such as as light pulse treatment, water-jet cleaning, pyrolysis, and chemical treatments.
A gulf between PV ambition and testing facilities
Though it already hosts several of the world’s largest PV installations, the Middle East and North Africa (MENA) region’s solar industry is still young, with limited local infrastructure and expertise. Project developers are learning quickly that building PV in harsh desert environments requires a careful eye on quality. New testing laboratories are looking to meet demand.
Chinese PV Industry Brief: Beijing probes EU investment barriers for PV
The Chinese government is launching an investigation to determine whether the European Union is blocking Chinese solar investments.
Microclimates could bolster case for agrivoltaics
A new paper finds that combining photovoltaics with crop farming can result in revenue gains over the life of a PV system at a diverse range of locations in the United Kingdom. Researcher Aritra Ghosh tells pv magazine that the benefits of agrivoltaics are “multifaceted.”
Solar panel cleaning with electromagnetic waves
Three companies, including US-based startup Sol Clarity, are experimenting with electrodynamic screen systems to clean solar panels using minimal electricity and no water.
Polysilicon prices stabilize at low levels amid market downturn
In a new weekly update for pv magazine, OPIS, a Dow Jones company, provides a quick look at the main price trends in the global PV industry.
All-perovskite tandem solar cell based on tin-lead perovskite achieves 27.8% efficiency
Scientists in the United States have fabricated an all-perovskite tandem solar cell that reportedly shows reduced interfacial energy loss in the cell’s top device. It was built with a hole transport layer based on a compound known as P3CT that was doped with lead iodide.
Residential PV power forecasting method based uniquely on direct radiation
Researchers in Spain have created a novel PV forecasting method that uses only direct radiation as a parameter. They found it to be “comparable, if not superior” to four established forecasting techniques. The method could help homeowners with PV systems decide when to use electricity-intensive appliances and cleaning systems.
