2. 1. Emerging Energy Possibilities

   Author : Joanna Wiberg; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; electron transfer; dye-sensitized solar cells; D-B-A; femtosecond transient absorption;

   Abstract : This Thesis presents a thorough study of the electron transfer (ET) processes, both inter-molecular - between dyes for dye-sensitized solar cells (DSSCs), and intra-molecular - in porphyrin based electron donor-bridge-electron acceptor model systems. The focus has been on charge separation and subsequent re-combination in the femtosecond-nanosecond range in both systems. READ MORE
