Cellules photoélectrochimiques de phtalocyanine d'hydroxyaluminium déposées par rotation
Keyword(s):
The spin-coating technique was used to produce hydroxyaluminum phthalocyanine (PcAlOH) photoelectrochemical cells. The spectral and electrical behavior of NESA/PcAlOH/BQ/HQ/Pt cells is studied and comparisons are made with cells based upon sublimed PcAlOH films. Due to the weak solubility of PcAlOH in volatile organic solvents, the DMSO used in the spin-coating method seems to be trapped in the solid film, and leads to a decrease in the photoelectrochemical cell efficiency. Studies on the influence of the counter-electrode showed that a vanadium counter-electrode gave higher values of Jsc, Voc, and η than a platinum one, but corrision phenomena were observed in that case.
