Surface Photovoltage Analysis of Photoactive Materials - Hardcoverby Thomas Dittrich (Author), Steffen Fengler (Author) Surface photovoltage (SPV) techniques provide information about photoactive materials with respect to charge separation in space. This book aims to share experience in measuring and analyzing SPV signals and addresses researchers and developers interested in learning more about and in applying SPV methods. For this purpose, basics about processes in photoactive materials and principles of SPV
