Inverted organic solar cells with polymer-modified fluorine-doped tin oxide as the electron-collecting electrode …
We report on inverted solar cells using amine-containing polymer (polyethylenimine ethoxylated, PEIE) modified fluorine-doped tin oxide (FTO) as the electron-collecting electrode. PEIE lowers the work function of FTO from 4.6 eV to 3.8 eV, measured by Kelvin probe, sufficiently low for collecting electrons in solar cells. ...
