Scientists fabricate high-performance large-area perovskite submodules for solar cells

Jul 29, 2022 (Nanowerk News) Perovskite solar cells (PSCs) are promising solar technologies. Although low-cost wet processing has shown advantages in small-area PSC fabrication, the preparation of uniform charge transport layers with thickness of several nanometers from solution for meter-sized large area products is still challenging. Recently, a research group...

Seeing double for better solar cells

Jul 29, 2022 (Nanowerk News) A new material can make solar cells a thousand times thinner than today’s silicon solar cells. This material is a hybrid organic–inorganic crystal called halide perovskite. Now, a novel approach allows scientists to watch changes in the material’s structure and functional properties at the same...

A paper battery with water switch

Jul 29, 2022 (Nanowerk News) A team of researchers at Empa developed a water-activated disposable paper battery. The researchers suggest that it could be used to power a wide range of low-power, single-use disposable electronics – such as smart labels for tracking objects, environmental sensors and medical diagnostic devices –...

Hydrogen production and carbon capture

Jul 29, 2022 (Nanowerk News) Hydrogen production takes place using natural gas as the raw material, combined with a very special ceramic membrane. Both hydrogen production and CO2 capture are achieved in a single step, which makes the method highly energy efficient. This is why the technologyhas been the subject...

Researching components made of natural fibers

Jul 28, 2022 (Nanowerk News) 3D printing has been in use in architecture for a while, and now it is to become ecologically sustainable as well: Together with partners, the Laser Zentrum Hannover e.V. (LZH) is researching how to produce individual building elements from natural fibers using additive manufacturing. In...

Greener air-conditioning for a warmer world

Jul 28, 2022 (Nanowerk News) When the heat of summer hits, air conditioners turn on and energy demand skyrockets, straining the grid. In a warmer world, more efficient cooling options will play an important role in curbing the increase of cooling-related energy demands. This will be particularly true for the...

Reducing food waste with novel biomaterials technologies

Jul 28, 2022 (Nanowerk Spotlight) Food waste reduction offers multi-faceted wins for people and planet, improving food security, addressing climate change, saving money and reducing pressures on land, water, biodiversity and waste management systems. Consider the staggering scale of the problem: Data gathered by the FAO, the Food and Agriculture...
