EPFL Scientists Achieve Record-Level Reproducibility for Perovskite Solar Cells
Perovskite solar cells hold much promise for cost-effective solar energy. However, heat stability is an issue, and can significantly limit the solar cell’s long-term efficiency. A team of scientists led by Michael Grätzel’s lab at EPFL has now developed a cesium-containing perovskite solar cell that has achieved efficiency of 21.1%, as well as record-level reproducibility. The work is published in Energy and Environmental Science.
By adding cesium, the EPFL scientists, led by postdoc Michael Saliba, made the first ever triple-cation perovskite mixture (Cs/MA/FA). The new films are more heat-stable and less affected by fluctuating surrounding variables such as temperature, solvent vapors or the heating protocol used for the device. But more importantly, they also show stabilized power-conversion efficiencies of 21.1% and outputs at 18% under operational conditions, even after 250 hours.
“This is an absolute breakthrough,” says Michael Saliba. “These properties are crucial for commercializing perovskite photovoltaics, especially since reproducibility and stability are the main requirements for cost-effective large-scale manufacturing of perovskite solar cells.” Source AZOCleantech...

HPS EnduraCoilTM Cast Resin Medium Voltage Transformer
HPS EnduraCoil is a high-performance cast resin transformer designed for many demanding and diverse applications while minimizing both installation and maintenance costs. Coils are formed with mineral-filled epoxy, reinforced with fiberglass and cast to provide complete void-free resin impregnation throughout the entire insulation system. HPS EnduraCoil complies with the new NRCan 2019 and DOE 2016 efficiency regulations and is approved by both UL and CSA standards. It is also seismic qualified per IBC 2012/ASCE 7-10/CBC 2013. Cast resin transformers are self-extinguishing in the unlikely event of fire, environmentally friendly and offer greater resistance to short circuits. HPS also offers wide range of accessories for transformer protection and monitoring requirements.
