US scientists have discovered a lead-free perovskite material with ferroelectric properties that can be used in solar cells. The perovskite compound was grown from cesium germanium tribromide and initial analysis shows that it produces ferroelectricity.

Scientists compared hydrogen storage techniques and found that physical methods are closer to commercial feasibility, while materials-based techniques have strong potential.

Scientists in Germany have improved the efficiency of an industrial TOPCon solar cell from 23.8% to 24.1% by using laser-enhanced contact optimization as a post-firing treatment.

Korea Electric Power Corp. will act as a sales intermediary under South Korea’s so-called K-RE100 scheme.

In July, PPA prices rose significantly in all major European energy markets except Germany, Pexapark says in a new report.

Dutch startup Elestor has secured funds to bring its hydrogen bromide (HBr) flow battery technology closer to commercial production. It said the system could achieve a levelized cost of storage below $0.05/kW.

An Iranian research group has developed a system that combines photovoltaic-thermal modules with organic Rankine cycle, a proton exchange membrane electrolyzer, and liquefied natural gas. The ideal system has an exergy efficiency of 16.24%, a cost rate of $4.48 per hour, and 33.32 kW of net electrical power.

Yingli’s 156-cell Panda 3.0 PRO module has a temperature coefficient of -0.30% per degree Celsius and is available in wattages ranging from 590 W to 615 W, with a bifaciality of more than 90%.

Dutch energy suppliers are arbitrarily setting net-metering tariffs for solar installations by taking advantage of a legal vacuum. However, Dutch PV analyst Peter Segaar says that current tariffs remain attractive.

Enphase is now waiting for final approval from the EU authorities and expects to finalize its plans to buy GreenCom Networks in the fourth quarter.
