Headline: Perovskite solar cells: Vacuum process may offer a short track to commercialization

■ Release Date: 2024.3.14

■ Published by: Karlsruher Institut für Technologie (KIT)

■ Keywords: perovskite, solar cells, silicon

■ Abstract:

Which process is best suited for mass production of perovskite solar cells? While solvent-based manufacturing processes are used in laboratories around the world, vacuum vapor-phase deposition processes are still the standard for the production of thin films for photovoltaics or organic light-emitting diodes. A new study that reveals major differences in the scientific discussion of these production processes.

Headline: Researchers prove fundamental limits of electromagnetic energy absorption

■ Release Date: 2024.3.14

■ Published by: Duke University

■ Keywords: electromagnetic, energy, radiation

■ Abstract:

Electrical engineers have determined the theoretical fundamental limit for how much electromagnetic energy a transparent material with a given thickness can absorb. The finding will help engineers optimize devices designed to block certain frequencies of radiation while allowing others to pass through, for applications such as stealth or wireless communications.

Headline: An electricity generator inspired by the drinking bird toy powers electronics with evaporated water

■ Release Date: 2024.3.14

■ Published by: Cell Press

■ Keywords: electricity, energy, fuel

■ Abstract:

Inspired by the classic drinking bird toy, scientists have developed an engine that efficiently converts energy from water evaporation into electricity to power small electronics. The device produces energy outputs exceeding 100 volts -- much higher than other techniques that generate electricity from water -- and can operate for several days using only 100 milliliters of water as fuel, according to a new study.
