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...
PVinsights:Cooling global demand undermines solar prices
Both multi-crystalline and mono-crystalline modules extend the price slump this week amid the lingering weakness in global demand. In particular, the demand in China observes an obvious weakness, which results in inventory increasing for Chinese module makers. Hence, the solar panel price in China sees the continuous drop as Chinese module makers are trying to reduce the inventory level through the strategy of the price reduction. In Japan and India, due to slower demand, the escalating price competition from Chinese players drives the solar panel prices down.
