Understanding of Hybrid Organic Inorganic Perovskites (HOIPs) Could Lead to Novel Solar Cells

Posted by MSE Supplies on

In a discovery that could have profound implications for future energy policy, scientists at Columbia University have demonstrated that it is possible to manufacture solar cells that are far more efficient than existing silicon-based cells by using a new kind of material. MSE Supplies is a leading supplier of FTO and ITO glass substrates for solar cells research.  Custom patterns can be fabricated based on customer provided drawings.  The team, led by Xiaoyang Zhu, a professor of chemistry at Columbia University, focused its efforts on a new class of solar cell material known as hybrid organic inorganic perovskites (HOIPs). Their results,...

Perovskite Solar Cells >20% Efficiency Enabled by A Vacuum Flash–assisted Solution Process

Posted by MSE Supplies on

EPFL's Michael Graetzel and his team found that, by briefly reducing the pressure while fabricating perovskite crystals, they were able to achieve the highest performance ever measured for larger-size perovskite solar cells, reaching over 20% efficiency and matching the performance of conventional thin-film solar cells of similar sizes. Their results are published in Science.

'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...

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...
