In the future, photovoltaic cells could be "worn" over clothes, placed on cars or even on beach umbrellas. These are just some of the possible developments from a study published in Nature Communications by researchers at the Physics Department of the Politecnico di Milano, working with colleagues at the University of Erlangen-Nuremberg and Imperial College London.
Light-emitting diodes (LEDs) are changing the lighting and display industry and have obtained significant advances than traditional lighting sources. The traditional materials LEDs, e.g., III-V semiconductor LEDs, organic LEDs (OLEDs) and quantum-dot LEDs (QLEDs), have achieved great success and gradually realized commercialization, but still face some challenges.
Around the world there are currently more than 18 billion internet-connected mobile devices. In the next 10 years, anticipated growth in the Internet of Things (IoT) and in machine-type communication in general, will lead to a world of hundreds of billions of data-connected objects. Such growth poses two very challenging problems:
Isn't it convenient when office building windows adaptively darken according to the intensity of sunlight- Or when standard glasses turn into sunglasses under the sun and switch back as you enter a building- Such feats are possible thanks to photochromic materials, whose optical (and other) properties change radically when irradiated by visible or ultraviolet light.
A long-cherished dream of materials researchers is a solar cell that converts sunlight into electrical energy as efficiently as silicon, but that can be easily and inexpensively fabricated from abundant materials. Scientists at the Helmholtz-Zentrum Berlin have now come a step closer to achieving this.
Multiple-cation and mixed halide (FAMACs) perovskites developed by adding Br/MA/Cs ions into the FAPbI3 perovskites are known to be the ideal compositions for use in high-efficiency photovoltaic and photoelectronic devices thanks to their reduced hysteresis, suppressed ion migration, and improved stability.
Studies on foldable electronics have gained huge momentum with the recent development of foldable mobile phone screens. A specifically valuable application of foldable technology is in solar panels.
Scientists at Osaka University have created lithium-ion battery (LIB) electrodes with silicon (Si) swarf or graphite sheet composites. This helped achieve a reduction in cost, environmental friendliness, and high performance.
For more than a century, optical coatings have been used to better reflect certain wavelengths of light from lenses and other devices or, conversely, to better transmit certain wavelengths through them. For example, the coatings on tinted eyeglasses reflect, or "block out," harmful blue light and ultraviolet rays.
Carbon dioxide (CO2) is one of the major greenhouse gases causing global warming. If carbon dioxide could be converted into energy, it would be killing two birds with one stone in addressing the environmental issues.
