### 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.
