Photoelectrochemistry of some aluminum phthalocyanines in regenerative solar cells

Article abstract of DOI:10.1149/1.2097296

Chloroaluminum phthalocyanine (ClAlPc) films sublimed with a high growth rate on SnO₂ can be made to undergo two transformations when the films are in contact with an acidic (HCl) aqueous solution: transformation I is obtained if the solution contains I_3-I_- and transformation H occurs when there is no redox couple in the solution. The short-circuit photocurrents produced by these two transformations are different. Their photoactivities are smaller and their J-V characteristics indicate an increase of J₀ after transformation of the film, as in the case of the high growth rate ClAlPc. A fluoroaluminum phthalocyanine film does not undergo any transformation I upon contact with an I_3-I_- acidic aqueous solution. Also, there is no rectification for this film and its photoactivity is very low. Scanning electron micrographs (SEM) reveal morphology differences between films of different phthalocyanines but no differences are observed by SEM, for the phthalocyanine films, before and after transformation I or H.
