Scientists working on perovskite solar cells at the Federal Institute of Technology in Lausanne, Switzerland, have proposed a standardized method for measuring the stability and degradation of perovskite solar cells in order to reach consensus and accelerate the commercialization of the technology.
Over the past few years, perovskite solar cells appear to be on the verge of commercialization, and the issue of stability and rapid degradation remains a major factor in the recovery of technology from commercialization.
Leading research institutes around the world have provided a series of solutions for this purpose - the proposed methods include grinding of steel mills and treatment of cells under precise exposure to light and moisture--EPFL published a paper stating standardization stability Sex and degradation of perovskite solar cells allow scientists to compare different methods more effectively.
“We designed and built a dedicated system to conduct this research. This is the latest technology to measure the stability of solar cells,†said the lead author of Paper Konrad Domanski. "We can change the light intensity of the sample and control the temperature, atmosphere, etc. We load the sample, program the experiment, and plot the data automatically.
The “Systematic Study of the Effect of Operating Conditions on the Degradation Behavior of Perovskite Solar Cells†published in the journal “Natural Energy†reveals how perovskite solar cells can be kept in dark conditions for several hours. This mainly affects the test results and lifespan. estimate.
Domanski continued: “We did not try to force community standards.†Instead, at the forefront of perovskite solar cells and their stability studies, we tried to lead by example and stimulate discussion about how these standards should be. We firmly believe that the specific protocol will be adopted by consensus and that a dedicated task force involving a wide range of researchers will be formed for this purpose.
