Conclusions and Outlook

Abstract

This work explores the synthesis of alternative graphene based materials and their applications in optoelectronics, focusing on photovoltaic and photodetector devices. It introduces innovative chemical synthesis methods for graphene products, emphasizing environmentally friendly processes that yield materials with exceptional electrical, optical, and chemical properties. Notably, reduced graphene oxide (RGO) films exhibited transparency and tunability in work function, comparable to traditional materials like ITO. The study also developed graphene quantum dots (GQDs) with high photoluminescence, optimized for use in photodetectors. Subsequent chapters detail the application of these materials in MOSCAP devices and photodetectors, highlighting their significant potential to revolutionize optoelectronic device technology and pave the way for future innovations.
