German research institute Fraunhofer ISE has unveiled a new metallization process for heterojunction solar cells that reportedly increases power conversion efficiencies by over 0.1% while reducing silver consumption. A device built with the new technique achieved an efficiency of 23.2%.
Conceived by scientists in China, the device consists of a Fresnel lens, a PV cell, and liquid ionic thermocells (iTECs) with electrolyte flow. In can reportedly outperform CPV systems built with thermoelectric generators, both in terms of costs and efficiency.
Australian battery company Li-S Energy claims to have taken a significant step toward proving the safety of its semi-solid-state lithium-sulfur batteries, with the third-generation technology successfully passing a series of nail penetration tests.
The UK-based manufacturer said the new Ecomod 290HT products have a size ranging from 15 kW to 50 kW and a coefficent of performance of up to 4.9. The systems can reportedly achieve a flow temperature of 75 C.
Indian manufacturer Statcon Energiaa has introduced a single-phase grid-tie solar inverter intended for application in residential and small commercial buildings.
The 3.33 kW / 6.65 kWh lithium-ferro-phosphate battery offers home backup and storage of rooftop solar generation.
Researchers in Spain has found that combining PV power generation with fuel cells and battery storage may help homes considerably reduce their levelized cost of energy. Their simulation reportedly demonstrated homes may also become completely self-sufficient.
The European Hydrogen Bank’s pilot auction is delivering €720 million ($768.3 million) to seven renewable hydrogen projects in Finland, Norway, Portugal and Spain. Together, they plan to produce 1.58 million tons of renewable hydrogen over a period of 10 years.
Chinese manufacturer Huasun says it has achieved an efficiency of more than 26% for both G12R and G12 heterojunction (HJT) solar cells.
An international research team has developed a new type of perovskite solar cell by using 4-phenyl thiosemicarbazide (4PTSC) as a precursor additive. The device showed an improved open-circuit voltage and “exceptional” long-term stability.
