The aim of Dr Pivrikas’s research is to improve the performance of modern opto-electronic devices. Optoelectronic devices of interest include photovoltaic solar cells, photodetectors and photosensors, field-effect and electrochemical transistors, light-emitting diodes, chemical and bio-sensors, electrochemical systems, batteries, neurons, and cells. These devices and systems are typically made of novel materials and next-generation device architectures. This encompasses solid-state semiconductors (organic molecules, polymers, carbon structures, silicon, germanium, gallium nitride, selenium, perovskites), electrolyte-based systems (batteries, organic-inorganic interfaces), modern nanostructured materials (quantum dots and structures, nano-needles), and bio-systems (neurons, cells).
Since the performance of optoelectronic devices is mainly determined by the nature of electrical current, most of our work focuses on comprehensive experimental and theoretical studies of electrical conductivity, photoconductivity and optical properties.
