Photodetectors
Photodetectors are essential components in modern electronic devices that convert light signals into electrical signals. Also known as photosensors, these devices play a crucial role in various applications, from optical communication systems and imaging devices to industrial sensors and consumer electronics. The primary function of a photodetector is to detect and measure light, making it indispensable in fields such as telecommunications, astronomy, and photography.
With advancements in technology, photodetectors have become increasingly sophisticated, featuring improved efficiency, reduced noise, and enhanced sensitivity across a broad range of wavelengths. Infrared detectors, ultraviolet detectors, and visible light detectors are examples of specialized photodetectors catering to diverse applications.
Indoor Photovoltaics
Photovoltaic materials are at the forefront of renewable energy technology, serving as the essential components in solar cells. These materials possess unique properties that enable the conversion of sunlight into electrical energy through the photovoltaic effect. Common photovoltaic materials include silicon-based semiconductors, thin-film compounds like cadmium telluride and copper indium gallium selenide, and emerging technologies such as perovskites. The development and optimization of these materials play a pivotal role in enhancing the efficiency and affordability of solar energy systems, contributing significantly to the global shift toward sustainable power sources.
We are interested in exploring the potential of lead-free pnictohalides, chalcogenides and chalcohalides for self-powered radiation detectors and indoor photovoltaics
Computational Materials
Density Functional Theory (DFT) has emerged as a powerful and widely employed theoretical framework in the field of materials science, particularly in the study of optoelectronic materials. By employing DFT calculations, we optimize the design of new materials with tailored electronic and optical properties, thereby accelerating the development of advanced optoelectronic devices. This theoretical framework enables the identification of materials with specific bandgaps, charge transport characteristics, and optical absorption profiles, all crucial factors in the performance of optoelectronic devices.
