The Solliance Solar Energy Research Institute announced significant achievements in the thermal stability of perovskite technology. Solliance announced 3000 hours of test results at the EU PVSEC meeting in Brussels, Belgium. After thermal stress testing, battery performance is still 93% of initial performance. .
'Perovskite solar cells have received great attention because of their high power conversion efficiency, which proves stability and scalability,' said Mehrdad Najafi, a researcher at Solliance Solar Research. 'The two very important topics in the Solliance collaboration. It is the next step in the successful commercialization of this technology. Our recent results show that long-term exposure to thermal stress can result in stable perovskite solar cells. Further full lamination optimization and introduction of metal oxide by atomic layer deposition (ALD) After the layer, the thermal stability is significantly improved compared to our previous reference: the previous solar cell will not exceed 50% performance after 100 hours at 85oC; and we now prove 3000 hours at 85oC The post-performance loss is only 7%. This is an important step towards fully complying with IEC requirements'.
Adriana Creatore, associate professor of Applied Physics at Eindhoven University of Technology, a partner at Solliance Solar Research, added that in the past three years, the university has been working with TNO to improve the efficiency and stability of perovskite hybrid photovoltaic technology. The basic research on interface engineering between atomic layer deposition (ALD) metal oxide-based charge transport layer and perovskite absorbers has promoted the development of this photovoltaic technology.
The perovskite solar cells used in the test are reminiscent of the structure of translucent perovskite solar cells. The company announced earlier this year that it will produce 26.3% perovskite/crystalline silicon tandem solar cells. Solliance is currently It is working on the pilot-scale process equipment provided by its partners to apply this perovskite solar cell to a viable industrial process for the production of perovskite solar modules.
