• concentrations of co-adsorbent is an unavoidable constraint on the co-sensitization of organic dyes [18][28][29][30]. In order to avoid the co-adsorbent, one of the co-sensitizers can be used to counteract the aggregation of the other. Spectroscopic studies and excited-state dynamics of the two dyes can be
