This is the first and most comprehensive guide on the modeling, engineering and reliable design of indoor photovoltaics which currently is the most promising and energy efficient power supply for edge nodes for the Internet of Things and other indoor devices.

Indoor photovoltaics (IPV) has grown in importance over recent years. This can in part be attributed to the creation of the Internet of Things (IoT) and Artificial Intelligence (AI) along with the vast amounts of data being processed in the field, which has been a massive accelerator for this development. Moreover, since energy conservation is being imposed as the national strategy of many countries and is being set as a top priority throughout the world, understanding and promoting IPV as the most promising indoor energy harvesting source is considered by many to be essential these days.

The book provides the engineer and researcher with guidelines, and presents a comprehensive overview of theoretical models, efficiencies, and application design. This unique and groundbreaking book has chapters by leading researchers on:

• Introduction to micro energy harvesting
• Introduction to indoor photovoltaics
• Modeling indoor irradiance
• Characterization and power measurement of IPV cells
• Luminescent solar concentrators
• Organic photovoltaic cells and modules for applications under indoor lighting conditions
• High-efficiency indoor photovoltaic energy harvesting
• Indoor photovoltaics based on ALGAAs alloys

Monika Freunek (Müller) studied Mechatronic and Product Engineering at the Universities of Applied Sciences of Bielefeld and Furtwangen, Germany from 2002-2006. After graduation and postdoctoral research at IBM Research Zurich, she worked as a researcher and co-founder of a start-up. Monika Freunek is now at BKW, Switzerland, as an energy specialist. Her main focus in research is modeling of energy and photovoltaic systems under different application conditions. She is an expert in indoor photovoltaics and has edited Photovoltaic Modeling Handbook (Wiley-Scrivener 2018).
