Solar energy utilization has been vital to cope up with the energy demands and at the same time to reduce the carbon footprint in the atmosphere. Many technologies evolved in the last three decades, with a common goal of effectively and economically harvesting solar photons. Among them, photoelectrochemical devices stood out because this concept can be applied not just for the solar energy conversion to electricity but also to store them in the form of chemical fuels. Overall objective of this course would be to introduce students, the fundamentals of photoelectochemistry to its application in solar energy conversion to electricity and fuels. At the end of the course, students should be able to read research papers related to solar cells, water splitting and carbon dioxide reduction, without much of scientific assistance. This course will help researchers in solar energy to strengthen their fundamentals and give aspiring researchers a good starting platform to pursue their career in solar energy. Course
