Germany’s Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE) introduced at this time that it has achieved an influence conversion effectivity of 31.6% for a perovskite-silicon tandem photo voltaic cell.
The outcome was confirmed by Fraunhofer ISE’s calibration laboratory CalLab.
The researchers defined that that cell consists of a prime perovskite PV machine based mostly on heterojunction expertise textured with micrometer-sized pyramids and an ordinary silicon backside cell.
“The new 1 cm² photo voltaic cell is particular in that the perovskite layer on the highest of the cell is positioned on an industrially textured silicon heterojunction photo voltaic cell utilizing a hybrid manufacturing route,” the analysis institute mentioned in a press release. “The profitable use of textured customary silicon photo voltaic cells and the uniform use of the perovskite layer on the texturized floor are necessary necessities for the commercial manufacturing of perovskite silicon tandem photo voltaic cells.”
Group Leader Perovskite Materials and Interfaces at Fraunhofer ISE, Juliane Borchert, defined that the proposed course of combines vapor deposition and moist chemical deposition to make sure uniform deposition of the perovskite layer on the textured silicon floor.
The scientists didn’t present extra technical particulars of the photo voltaic cell.
“The tandem photo voltaic cell developed by Fraunhofer ISE consists of outcomes from analysis initiatives PrEsto and MaNiTU in addition to help from an intensive trade of scientists from King Abdullah University of Science and Technology (KAUST), ” they mentioned.
In May, KAUST introduced an effectivity of 33.7% for a 1 cm² perovskite-silicon photo voltaic cell. The European Solar Test Installation (ESTI) confirms the outcome.
