Laser Photonics Corp., a global leading industrial company in high-tech laser systems for laser cleaning, and other materials applications, today announces the launch of the CleanTech™ 3000-CTH laser cleaning system (3KW).
Perovskites are hybrid materials made from metal halides and organic compounds. They have attracted a lot of interest in the field of solar energy because of their light-harvesting capacities combined with a low cost of manufacturing, making them prime candidates for overtake the market from their silicon counterparts.
A research team co-led by chemists from City University of Hong Kong (CityU) and Imperial College London (Imperial College) has developed new, highly efficient and stable perovskite solar cells.
Solar cells will doubtless play a significant part in a sustainable energy future. Polymer solar cells (PSCs) specifically provide an excellent option because they are cheap to produce and can be both flexible and semitransparent.
New solar cell devices that are cheaper and easier to make could soon make their way to market thanks to materials made at Imperial College London.
A detailed view of how electrical charges behave inside perovskites could guide efforts to improve the performance of next-generation solar cells based on these materials, KAUST research has shown.
Perovskites are a family of materials that are currently the leading contender to potentially replace today's silicon-based solar photovoltaics. They hold the promise of panels that are far thinner and lighter, that could be made with ultra-high throughput at room temperature instead of at hundreds of degrees, and that are cheaper and easier to transport and install.
A German research team has developed a tandem solar cell that reaches 24 per cent efficiency – measured according to the fraction of photons converted into electricity (i.e. electrons). This sets a new world record as the highest efficiency achieved so far with this combination of organic and perovskite-based absorbers.
The technology enables completely new types of implants that can be used to stimulate nerve cells and was developed in a joint effort by researchers from Graz University of Technology (TU Graz), the Medical University of Graz (Med Uni Graz), the University of Zagreb and the Czech CEITEC. The basis of this technology involves colour pigments from the food industry, such as those used in organic solar cells.
For a greener and more sustainable economy, building better and more powerful solar cells is a key research goal within the clean energy sector. But, in a typical single-junction solar cell, performance is capped at what is called the Shockley–Queisser limit (a theoretical limit for the maximum efficiency that a solar cell can reach).
