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.
India’s ALMM list tops 50 GW of solar module capacity
The PV modules on India’s Approved List of Models and Manufacturers (ALMM) comply with the Bureau of Indian Standards and meet the Ministry of New and Renewable Energy’s (MNRE) module efficiency criteria for utility-scale, rooftop, solar pump, and solar lighting applications.
Longi, Aiko Solar, TCL Zhonghuan, Tongwei to post H1 losses
Longi says it expects a net loss of CNY 4.8 billion ($660.2 million) for the first half of 2024, while Tongwei is bracing for a CNY 3 billion loss. Aiko Solar and TCL Zhonghuan, meanwhile, are predicting losses of CNY 2.9 billion and CNY 1.4 billion, respectively.
German firm hits energy independence with solar, batteries, hydrogen
Esysteme21 has built a 100% self-sufficient energy system with photovoltaics, hydrogen and battery storage. The German solar company describes the concept as a solution for medium-sized enterprises.
China to impose stricter requirements on PV manufacturing
The new provisions are intended to reduce overcapacity in the market while selecting the most efficient technologies and products.
GoodWe unveils double-glass TOPCon bifacial solar modules
GoodWe has developed new double-glass tunnel oxide passivated contact (TOPCon) bifacial solar modules for its Polaris series, available in 525 W and 580 W variants.
VIPV in refrigerated trucks can ‘easily’ offset energy demand it creates and meet chiller demand
Germany’s Fraunhofer ISE investigated thermal effects and net energy gains of a 3.2 kW vehicle integrated PV (VIPV) system installed on a freight truck with a refrigerated cargo storage area. It found that with battery storage the system could potentially meet the entire energetic needs of the cooling unit throughout the year in some cases.
Solar tariffs could ‘unintentionally cede US leadership’
A new report from Clean Energy Associates (CEA) and the American Council on Renewable Energy shows how antidumping and countervailing duty (AD/CVD) tariffs create cost issues not just for imported solar panels, but for US-made solar panels as well.
U.S. researchers build 16%-efficient mini perovskite solar module resistant to UV light-induced degradation
A U.S. research team has built a 15 cm2 perovskite solar module with improved stability and efficiency thanks to a polymer hole transport layer that reportedly improves the panel stability and efficiency.
