Title: | Highly sensitive spectroscopic characterization of inorganic and organic heterojunctions for solar cells | Authors: | VANDEWAL, Koen GORIS, Ludwig HAENEN, Ken Geerts, Y MANCA, Jean |
Issue Date: | 2006 | Publisher: | EDP SCIENCES S A | Source: | EUROPEAN PHYSICAL JOURNAL-APPLIED PHYSICS, 36(3). p. 281-283 | Abstract: | Sub-bandgap absorption features (alpha <= 100 cm(-1)) have been detected in organic and inorganic semiconductors and their heterojunctions. Photothermal deflection spectroscopy (PDS) is used to increase the detection limit considerably with respect to common absorption spectroscopy. Results are presented on discotic liquid crystals, donor-acceptor complex formation in P3HT:PCBM solar cells and UV-induced defect generation in nanoporous TiO2. | Notes: | Hasselt Univ, Inst Mat Res, B-3590 Diepenbeek, Belgium.
