A scientist working on the research of perovskite solar cells at the Federal Institute of Technology in Lausanne, Switzerland, has 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 brink of commercialization, and the issue of stability and rapid degradation remains a major factor in the technological recovery from commercialization.
The leading research institutes all over the world are offering a range of solutions to this - with separate methods that include mill grinding processes and cells exposed to light and moisture for precise exposure - EPFL published a paper proposing standardized stabilization Sexually and biodegradable perovskite solar cells enable scientists to compare different approaches more effectively.
'We designed and built a dedicated system to conduct this research, the latest technology for measuring the stability of solar cells,' said the lead author of Paper Konrad Domanski. 'We can change the light intensity of a sample and control the temperature and atmosphere Etc. We load the sample, program the experiment, and draw the data automatically.
The systematic study of the influence of operating conditions on the degradation behavior of perovskite solar cells published in the journal Nature Energy reveals how perovskite solar cells can be kept under dark conditions for several hours, which mainly affects test results and lifetime estimate.
Domanski goes on to say: 'We are not trying to impose community standards.' Instead, we are trying to lead by example at the frontiers of perovskite solar cells and their stability studies and to stimulate discussion of how these standards should be. We are convinced that specific protocols It will be adopted by consensus, and for this purpose will form a panel of specialized operations involving a wide range of researchers.
