Sunlight Energy Conversion

Timetable

Module aim (aims)

The lecture will be devoted to the principles of photovoltaics and the systems used for solar fuels (mainly water splitting). The operation of solar cells of the first, second and third generation will be presented, the efficiency limits of various devices will be discussed, and the emerging branches of photovoltaics will be highlighted. Large part will be devoted to the recently widely studied sunlight conversion systems using nanomaterials and hybrid organic-inorganic composites. This lecture will be also accompanied with the presentations how to prepare simple low-cost solar cells (e. d. dye-sensitized solar cells) and how to characterize them using basic photovoltaic and spectroscopic measurements. The use of modern ultrafast laser spectroscopy tools used to study dye-sensitized and perovskite systems will be also emphasized.

Pre-requisites in terms of knowledge, skills and social competences (where relevant)
