Methods to determine the agglomerated–amorphous ratio of P3HT in P3HT:PCBM solar cell mixtures, and control the degree of agglomeration–crystallinity of P3HT in the final device using a solvent mixing method and no further heat‐treatment or preparation of the polymer are presented. As‐cast devices have an efficiency of ∼4%.
