'Zero-energy' buildings to be enabled by the world’s highest efficiency solar cells

Posted by MSE Supplies on

The world’s highest efficiency solar cells have been developed at the University of New South Wales, which could eventually lead to zero-energy buildings equipped with ultra-thin panels. The cells are made from CZTS, a mixture of copper, zinc, tin, and sulphur; the cells remove the toxicity and scarcity problems of cadmium and selenium mixtures usually used in thin-film panels, because all four materials are both common and non-toxic. “They can be deposited directly onto materials as thin layers that are 50 times thinner than a human hair, so there’s no need to manufacture silicon ‘wafer’ cells and interconnect them separately,” said Professor Martin Green, an expert in...

New Paper on Science: Is Indium Tin Oxide (ITO) the Material Photonics Has Been Waiting For?

Posted by MSE Supplies on

Large optical nonlinearity of indium tin oxide in its epsilon-near-zero region Authors: M. Zahirul Alam, Israel De Leon, Robert W. BoydScience 28 Apr 2016:DOI: 10.1126/science.aae0330   By Amy Nordrum Posted 28 Apr 2016 There are plenty of reasons why it’s useful to transfer information through photons or use light particles to carry out tasks within a system or device, speed chief among them. But in order to use photons with even greater dexterity in the future, researchers will need to control the way light behaves as it passes through a material. One way to do this is by adjusting the material’s refractive...

JACS: Efficient and Cheap Perovskite Solar Cells Have Been Developed

Posted by MSE Supplies on

Journal of the American Chemical Society published a new paper on April 18, 2016, titled "Exceptional Morphology-Preserving Evolution of Formamidinium Lead Triiodide Perovskite Thin Films via Organic-Cation Displacement".    Perovskites, thin films of crystalline materials, are a promising materials in developing efficient and cost-effective solar cells. Recently, a team of researchers from all over the world demonstrated a method to flip a chemical switch capable of converting one kind of perovskite into another kind - an enhanced light absorber containing improved thermal stability.  MSE Supplies is a leading supplier of both standard and custom-made FTO or ITO glass substrates for thin film...
