Tandem solar cell achieves 32.5% effectiveness
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.

Mass-Production all set 28.7% efficient solar cell fabricated in Germany
The record was set by energy solutions supplier Q CELLS as well as German research centre Helmholtz-Zentrum Berlin. The 28.7% effectiveness was accomplished for a 2-terminal tandem solar cell combining a mass-production all set silicon bottom cell based on Q.ANTUM modern technology as well as a top-cell based upon perovskite innovation.

Perovskite solar cells: Interfacial loss systems revealed
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.

Tandem solar cell globe record: New branch in the NREL graph
Tandem cells combine 2 various semiconductors that convert various parts of the light spectrum into electric power. Metal-halide perovskite substances primarily make use of the noticeable parts of the spectrum, while CIGS semiconductors convert rather the infrared light.
