Schott Solar it’s able to produce monocrystalline screen-printed cells with an efficiency of 20.2 %.
The record cell with a performance of 4.92 W has been produced in industrial format, i.e. 156 mm x 156 mm.
The high efficiency technology used by Schott Solar is the same which has been using for some time for multicrystalline cells.
Since January 2011, the company has only focused intensively on substances related to monocrystallines.
To achieve more than 19% efficiency it was relatively easy, reports Schott.
To get over 20%, Schott Solar cooperated with the Schmid Group and took advantage of their selective emitter technology.
Now, Schott wants to get started with manufacturing optimization to transfer the result to new modules.
The company will announce more details at the EU PVSEC at the beginning of September in Hamburg.
