Slimming down on silver

Using an innovative high-speed video setup, scientists in Germany were able to observe the screen-printing process used in solar cell metallization, on a time scale of less than 50 milliseconds. Insights into the paste’s behavior and the mechanisms at work during screen printing will improve the process and the formulation of the silver paste it relies on.

Perovskite structure also benefits batteries

Scientists at Germany’s Karlsruher Institute of Technology are leading an investigation into a new lithium-ion battery anode. The innovation has a perovskite crystalline structure and, according to the researchers, could provide strong all-round performance from simpler, cheaper production methods than those used for other anode materials.

Aerosols affect photovoltaic generation in Europe

The German meteorological service, the Karlsruhe Institute of Technology and solar forecaster Meteocontrol are investigating how weather events can be better factored in when forecasting solar power generation. The Federal Ministry of Economics is funding the ‘Permastrom’ research project with €2.5 million.

International consortium claims 25% efficiency for perovskite CIGS solar cell

Researchers led by Belgian institute imec claim to have achieved the result with a 1cm² perovskite tandem solar cell. The result tops the 24.6% efficiency the consortium announced in September 2018. The cell’s developers are now aiming for 30%.

A whole new KIT of solar cell materials

Scientists at Germany’s Karlsruhe Institute of Technology have received €4.5 million from the Carl Zeiss Foundation to begin a project developing an entirely new solar cell concept they say will combine the printability of organic PV, long-term stability of crystalline solar cells and ferroelectricity of lead-halide perovskites.

Calcium batteries cool down with new electrolyte

Scientists at Germany’s Karlsruhe Institute of Technology have developed a new class of electrolytes they say could bring calcium batteries – currently only a lab technology – a step closer to being a practical reality for energy storage.

German scientists team up for perovskite tandem cells

Two of Germany’s leading research institutes and a CIGS module maker have announced plans to work on the development of perovskite-CIGS tandem cells with a target of producing thin film modules with better than 30% efficiency.

European researchers want to develop digitally printed, highly efficient and stable perovskite PV modules

German and Greek scientists are working with industrial partners on the technological feasibility of making solar modules based on perovskite absorbers. The prototypes should be freely configurable in size, shape and color.
