Title: Maria K Chan: Innovator in Spectroscopy and Photovoltaics
Introduction
Maria K Chan is a distinguished inventor based in Burr Ridge, Illinois. She has made significant contributions to the fields of spectroscopy and photovoltaics, holding two patents that showcase her innovative spirit and technical expertise.
Latest Patents
One of her latest patents is for advanced X-ray emission spectrometers. This invention addresses the need for spectroscopy systems that require crystals with specific properties for analyzing the spectrum of a sample. The two-dimensional (2D) crystal mount allows for simultaneous spectroscopy measurements, enhancing the efficiency of element detection. The design includes a crystal holder with multiple rows of crystal mounts, each positioned to support a crystal at a fixed orientation relative to an optical axis. This innovation enables multiple simultaneous measurements, significantly improving the analytical capabilities of spectroscopy systems.
Another notable patent is for substituted lead halide perovskite intermediate band absorbers. Lead halide perovskites are recognized for their versatility as visible light absorbers, which are essential for traditional single-junction photovoltaics. Computational screening has identified both iron- and cobalt-substituted MAPbBr as promising intermediate band materials. The films were synthesized using conventional solution-based processing techniques. First-principles density functional theory (DFT) calculations support the existence of intermediate bands upon cobalt incorporation, which enhances sub-gap absorption. This research suggests that these materials hold great promise for intermediate band photovoltaics.
