IRENA calls 16.4% annual renewable growth to hit COP28 targets
Statistics from the International Renewable Energy Agency (IRENA) shows that if the world were to continue with a 14% annual growth rate in renewables capacity, as seen in 2023, it will fall 1.5 TW short of meeting deployment targets set at COP28.
Bifacial PV, single-axis tracking produces cheapest electricity, says IEA-PVPS
The IEA Photovoltaic Power Systems Programme’s (IEA-PVPS) latest factsheet covers bifacial PV modules and advanced tracking systems. It says a combination of bifacial modules with single-axis tracking could increase energy output by up to 35%.
Solar supply chain, technology trends, and policy update
A report from Clean Energy Associates (CEA) provides the latest on global and regional solar supply chains, technological trends, and market impacts from policy.
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.
Amazon hits 100% renewable energy goal seven years ahead of schedule
The retail giant matched 100% of the electricity used in its operations with investments in renewable energy in 2023.
Solar panel cleaning with electromagnetic waves
Three companies, including Massachusetts startup Sol Clarity, are experimenting with electrodynamic screen systems to clean solar panels using minimal electricity and no water.
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.
Organic solar cell gains counterintuitive efficiency boost from entropy
A research team at the University of Kansas found that organic semiconductors known as non-fullerene acceptors demonstrate a high solar cell efficiency due to a reversed heat flow.
REIT completes commercial-scale solar tax credit transfer
Solar developer Black Bear Energy said the real estate investment trust’s (REIT) transaction on the 556 kW portfolio is proof of concept that demand exists for credits of this size and risk profile.
With great (solar) power comes great responsibility
Consumer protection and transparency are the keys to reigniting industry growth. Josh Levine, vice president of marketing, EnergySage shares his perspective.
