Functional nanomaterials with intrinsically new and tailored properties are key elements for developing sustainable solutions for energy harvesting. This symposium will focus on new energy technologies and advanced nanodevices such as the emerging class of inorganic-organic hybrid perovskites, next-generation photocatalysts, solar hydrogen production devices, and eco-friendly multifunctional optoelectronic devices such as quantum-dot LEDs and flexible electronic devices.

Chemically processed functional nanomaterials have emerged as key materials to develop high performance flexible and stretchable optoelectronic devices for next generation display and energy harvesting applications. Perovskite solar cells (PSCs) manifest disruptive materials innovation in the field of energy harvesting due to their promising photoconversion efficiencies (> 25%), low cost, and easy solution processability. However, progress in device efficiency, long-term environmental stability, and lead-free technologies are essential for commercial uptake and deployment of perovskite solar cells. Photoelectrochemical (PEC) water splitting has emerged as a competitive technology being capable of converting solar energy directly into chemical energy using stable and efficient photocatalysts for solar hydrogen production. Recent developments based on novel materials and systems have led to significant advances in the fundamental understanding of light-induced charge dynamics and related interfacial chemical reactions and efficiencies as well as performance stability of such new systems that will be discussed in this symposium.

This international forum will present technological advances in functional materials for energy harvesting to meet the challenges of sustainable energy and environment technologies. Interested individuals are invited to contribute by submitting abstracts along the following topics.
