### Organic and Hybrid Solar Cells - An Introduction

Our new text book "**Organic and Hybrid Solar Cells: An Introduction**" based on the lecture "**The Physics of Organic and Hybrid Solar Cells**" given here at the University of Konstanz is now available at **De Gruyter**.

"Organic and Hybrid Solar Cells" is an introduction to the field of organic and hybrid photovoltaics. The authors take a focused approach to provide the reader with an overview of the most relevant scientific background as well as current research developments. Starting with a basic introduction to semiconductor physics, the book discusses inorganic and organic semiconductors and junctions, working mechanisms and architectures of organic, dye-sensitized, hybrid and perovskite solar cells, characterization techniques, and gives insights into fabrication, device lifetime and commercialization aspects of these exciting photovoltaic materials.

- Based on a lecture by the authors for master students.
- Detailed introduction to organic and hybrid solar cells – alternatives for low-cost, light-weight and flexible renewable energy.
- Covering fully organic, dye-sensitized, hybrid and perovskite solar cells.
- Explaining working mechanisms and characterization techniques.
- Giving an excellent overview over these emerging technologies.
