Fabrication and reliability of dye solar cells: A resonance Raman scattering study
Abstract In this work, the effect of reverse bias stress tests on Dye Solar Cells (DSCs) based on N719 dye was investigated in detail using resonant micro-Raman spectroscopy. First the Raman lines were assigned to vibrations from the different constituents in a fresh solar cell. Then the mechanism of thiocyanato (SCN − ) loss under stress conditions was reported.
