Metal Halide Perovskites: Exceptional Semiconductors for Optoelectronic Applications

IAS@NTU Discovery Science Seminar by Prof Subodh Mhaisalkar and Dr Annalisa Bruno

Metal-halide perovskites are one of the most promising active materials for optoelectronics applications such as as photovoltaic, light-emitting technologies, and X-ray detectors, thanks to their excellent optoelectronic properties and thin films fabrication versatility.

In less than 10 years, perovskite solar cells have achieved record power conversion efficiency of 25.5% and an increasingly growing operational stability. The rapid progress has triggered the interest in transferring the existing technology from laboratory small area perovskite solar cells into large-area solar modules.

The webinar gave an overview of the recent research activities on halide perovskite materials, from the synthesis to their optical and electrical properties, and finally to their integration in solar cells, as well as the different technologies explored to scale them up over large areas. Some interesting takeaway from this webinar was seeing how perovskites PV cells are manufactured using industrial viable methods and the possibility of making perovskites PV cells transparent thus opening up numerous possibilities for its application.

This topic being one of the forefronts of renewable energy and covering numerous multidisciplinary fields, had attracted students from various NTU schools. The webinar was definitely an eye-opener into the field of perovskites photovoltaics and was well received by all, as climate change and renewable energy is a current hot topic.
