First Solar sues JinkoSolar for alleged TOPCon patent infringement
First Solar has sued JinkoSolar in a US federal court in Delaware, claiming that the Chinese manufacturer infringed upon US Patent No. 9,130,074, which is related to tunnel oxide passivated contact (TOPCon) solar technology.
New method to predict potential induced degradation in glass-glass TOPCon solar modules
A research group led by Chinese manufacturer Trina Solar has outlined a new approach to predict potential induced degradation (PID) in dual-glass solar panels under multiple typical field conditions. The novel methodology is claimed to facilitate simultaneous PID and light exposure.
Bosch unveils residential heat pumps based on inverter ducted split tech
The new product series uses R-454B as the refrigerant and is available in four versions.
Dubai issues tender for 7th phase of giant solar park
The Dubai Electricity and Water Authority (DEWA) has launched a tender for the seventh phase of the Mohammed bin Rashid Al Maktoum Solar Park, which could add up to 2 GW of PV capacity and 1 GW of battery storage.
Weil-McLain launches dual-fuel heat pumps for residential, light commercial applications
The US-based heating specialist said its new air-to-water heat pumps use difluoromethane as the refrigerant and have a coefficient of performance of up to 5.37.
TU Delft research suggests back contact tech may push crystalline silicon PV over 28% threshold
Researchers in the Netherlands have investigated how carrier-selective contacts may help achieve stronger performance in back-contact (BC) crystalline silicon solar cells and have predicted efficiencies may reach up to 28.64%. Their analysis considered work function, energy barriers, and energy alignment across the stack of layers.
Polyshine Solar unveils ultralight, flexible rooftop solar panels
The Chinese manufacturer said its new flexible modules have an efficiency of up to 20.1% and a weight of only 7.5 kg, or 2.92 kg/m2. The new products have purportedly a light transmittance of over 91% and “ultra-high” UV blocking ability.
Fraunhofer institutes developing electrocaloric solid-state heat pump without compressors
Six Fraunhofer institutes are developing new electrocaloric heat pumps that use elastocaloric heat pipes instead of compressors to extract heat from the sources. The first pilot systems developed by the research team achieved an electrical efficiency of 99.74%.
PVT-assisted air-source heat pump based on phase-change tank
Scientists in China have designed a photovoltaic-thermal integrated air-source heat pump hot water system that uses a phase change tank to lower energy consumption and achieve higher power generation performance than conventional heat pumps. The system is designed to use water as a working medium and to provide circulation power for forced circulation.
Longi sues JinkoSolar for alleged patent infringement in China, United States
Longi filed the lawsuit in China at the Jinan Intermediate People’s Court in Shandong, demanding an immediate halt to the manufacturing, sales, and offers to sell the allegedly infringing products. The lawsuit in the United States was filed at District Court for the Eastern District of Texas.
