Uncover the key to perovskite solar cell stability with groundbreaking research on ion-induced field screening by Martin Stolterfoht and team.

Revolutionary non-laser method for perovskite solar modules achieves 21.7% efficiency and 98% fill factor, surpassing traditional techniques. Major breakthrough in solar technology.

Experience the world's top tandem solar cells with record efficiency values of up to 33.7%. Expert teams from the Helmholtz-Zentrum Berlin (HZB) and other research institutes are now making these technologies available in principle and potentially low cost.

Researchers from Germany's Helmholtz-Zentrum Berlin (HZB) and also HTW Berlin have taken a look at exactly how precursor inks influence the quality of perovskite thin films. The best cells were scaled approximately minimodule dimension. The team revealed that when slot-die covering the halide perovskite layers on large locations, ribbing results may occur yet can be protected against by adjusting the precursor ink's rheological properties.

Nano-textured surface areas are an interesting strategy for maximizing the optical qualities for monolithic perovskite/silicon tandem solar cells. Researchers from Germany's Helmholtz-Zentrum Berlin (HZB) have actually checked out the growth of different textures of silicon surface areas making use of different industrial additives as well as their efficiency in silicon heterojunction (SHJ) and also SHJ-- perovskite tandem solar cells.

Perovskite semiconductors promise highly efficient and affordable solar cells. Nonetheless, the semi-organic product is very sensitive to temperature differences, which can swiftly cause fatigue damages in typical outdoor usage. Adding a dipolar polymer compound to the precursor perovskite solution assists to neutralize this.

The existing globe record of tandem solar cells containing a silicon bottom cell as well as a perovskite top cell has once again been broken at HZB. The new tandem solar cell converts 32.5% of the case solar radiation right into electric power.

Operating in consortium with CSEM, Helmholtz-Zentrum Berlin, Fraunhofer ISE, as well as the University of Stuttgart, Meyer Burger is looking into tandem solar cells and developing next-generation solar modules These activities center around the automation of the new technologies, or large scale production of solar cells with efficiencies of more than 30 percent

South Korea-based Qcells and also a European research study group (led by Helmholtz-Zentrum Berlin (HZB)) have actually jointly established a pilot manufacturing line for silicon-perovskite tandem cells in Thalheim, Germany. The project intends to speed up the innovation's mass production as well as market infiltration. The project started on 1 November.

Tandem cells made from silicon and perovskite are able to convert the wide power range of sunlight into electrical energy extra successfully than the respective single cells.

A global group of experts has collected data on metal halide perovskite solar cells from greater than 15,000 publications as well as developed a data source with visualization alternatives as well as analysis tools. The database is open source and provides an introduction of the rapidly growing understanding along with the open questions in this exciting class of products. The research study was launched by HZB scientist Dr. Eva Unger as well as carried out and also coordinated by her postdoc Jesper Jacobsson.

The result was certified by Germany's Fraunhofer Institute for Solar Energy Systems' (ISE) CalLab as well as included in the charts of the united state Department of Energy's National Renewable Energy Laboratory.

Losses take place in all solar cells. One cause is the recombination of cost carriers at the interfaces. Intermediate layers at such interfaces can reduce these losses via so-called passivation. Self-assembled monolayers (SAMs) with a carbazole core are particularly well suited for the passivation of semiconductor surfaces constructed from perovskite products.

In simulations as well as experiments, researchers demonstrate that introducing small nanoscale texturing on the surfaces of products in perovskite/silicon tandem solar cells can dramatically increase efficiency by decreasing the quantity of light energy that is lost as a result of representation.

Utilizing a conductive atomic force microscopic lense, they scanned the solar cell surfaces and also discovered small, nanometre-sized channels for the destructive dark currents, which are due to disorder in the a-Si: H layer.
