A new method to aid large‐area solution processing of organic small molecule semiconductors is reported. A thermally degradable poly(propylene carbonate) (PC) binder is added to a solution of soluble precursor to a tetrabenzoporphyrin to increase its viscosity, allowing for the use of large‐area methods such as inkjet printing, slot coating, or blade coating. This method is used to make bulk heterojunction solar cells with a p ‐ i ‐ n type structure.
