Perovskite solar cells: TEAM PV develops protocols to ensure reproducibility
Helmholtz-Zentrum Berlin
We perform user-inspired energy materials research and operate the world-class synchrotron BESSY II in Berlin, Germany.
Ten teams at Helmholtz-Zentrum Berlin are building a long-term international alliance to converge practices and develop reproducibility in perovskite materials. The TEAM PV project is funded by the Federal Ministry of Education and Research ( Bundesministerium für Bildung und Forschung ), Germany.
Solar energy is already the cheapest way to generate electricity in many parts of the world. But the world needs much higher efficiency solar modules to power demanding sectors such as electric vehicles, steel production, and AI. Likely the only option for increasing efficiency within the next decade is halide perovskites, a new class of materials that has been the subject of intensive research in the last decade. And while the silicon modules that dominate the market today are mainly produced in China, production facilities for halide perovskite cells could also be set up in Europe and the US, de-risking supply chains.
However, the road from the laboratory to mass production is long and there are still a number of hurdles to overcome. "We urgently need common protocols to reliably compare diverse global developments in these novel materials and also to predict their service life," says Dr Dr. Siddhartha Garud , who drives the management of the TEAM PV project at HZB. Within this project, HZB aims to converge best practices in fabrication and analyses together with the National Renewable Energy Laboratory NREL, the 美国科罗拉多大学博尔德分校 and Humboldt-Universit?t zu Berlin .

One of the main questions is how the stability determined in a laboratory will behave under real conditions in a field. Another focus will be on machine learning methods to navigate this extremely vast class of materials and devices. The participating teams will work closely together to further develop the fabrication and analysis of perovskite thin films and full devices.
The BMBF is providing a total of €4 million in funding for the TEAM PV project for tools, personnel and researcher exchanges. "We want to establish a long-term partnership in photovoltaics with sustained researcher exchanges and also make it a starting point for further collaborations between the Helmholtz Association and National Labs and top Universities in the U.S.", Garud says.

1 个月Dr. Sateesh Prathapani Anupam Yadav, ir. Dr., I hope it was not missed that a paragraph in the article opens with, "One of the main questions is how the stability determined in a laboratory will behave under real conditions in a field." Our colleagues at NREL already made one high impact publication on it last year (linked below). The photo captions are also about the lab where "different compositions of the material can be prepared" and where cells are tested in, "in real life conditions". I hope this address at least some of your concerns. https://www.nature.com/articles/s41586-023-06610-7

1 个月Dear Dr. Sateesh Prathapani, Ecehan ?evik and Anupam Yadav, ir. Dr., I am working on this project and yes - the post might have been misleading to you. Stability/reliability are core topics of this project - of course! And there is more, of course! We need statistics in our stability studies, therefor reproducability -the word that obviously triggered you- was a term that we mentioned in project meetings and that made it into the first words of this post.

1 个月It's already Reproducible, it's not the current problem! My point is clear, to bring Perovskites to the market stability and equally toxicity are the two challenges to overcome!! Have enough courage to spend money and time working on these two objectives!! Efficiency and scalability challenges already have been solved over the previous decade!! Unfortunately I see people keep pushing what works best with academic quest...and wait for someone to solve the actual problems then strategically take over later!! Unfortunately, I found that this approach is prevailing across the world and surprisingly it's working!!

1 个月It is showing not much things actually, first you have to complete the device. After that you have to measure and compare the efficiencies. The goal is Reproducing that 1in to 1in devices and make them sustainable? or meaningful to just looking that small devices an estimate the big panels behaviour? 4 million dollar is a good money for that.
