Development of new systems for photovoltaics has focused on inexpensive, abundant, and non-toxic nanostructured materials, and novel concepts for the conversion of solar energy into electrical energy. Related to these developments, tremendous advances have been made in the synthesis and characterization of nanomaterials, charge separation dynamics and charge transfer kinetics at interfaces in a large variety of configurations. New materials include nanostructured inorganic materials, such as metal oxides, sulfides, and selenides, etc., organic materials, such as small molecular systems or (semi)conducting polymers, and hybrid materials, containing both inorganic and organic components. In addition, there has been a strong surge in research in photoelectrochemical energy conversion, for example, by solar water splitting of CO2 photoreduction. The current champion system, however, is the hybrid perovskite solar cell, which was developed as a sub-configuration of the dye solar cell, but which has shown to be a novel and unique photovoltaic system, with a confirmed record efficiency of 22%. A thorough understanding of the fundamental aspects of these new systems is essential to be able to understand the presentations that will be given in Symposium B6: Photovoltaics, Solar Energy Materials and Technologies.

This tutorial course entitled Next-generation solar cell materials and characterization aims to guide students and researchers new to this exciting field, and explain the important aspects of materials synthesis and characterization, device configurations for solar energy conversion, and advanced characterization methods for the elucidation of fundamental processes in these complex systems. The two instructors are both experts in this field, and bring complementary experiences to the tutorial course. Dr. Teoh is an expert in synthesis and characterization of novel, nanostructured materials, and photogenerated charge carrier dynamics, in particular for photoelectrochemical reactions, including solar water splitting, CO2 reduction, and photo-oxidation processes. Dr. Anta is an expert in the fabrication and characterization of third-generation solar cells based on nanomaterials, with a particular interest in the use of small-signal perturbation methods to study the carrier dynamics, including transport and recombination.
