Diluting concentrated solution (DCS) is a new, simple, general and effective approach to improve power conversion efficiencies (PCEs) of polymer solar cells (PSCs). PCEs of binary blend PSCs, ternary blend PSCs and all-polymer solar cells fabricated using this method are enhanced by a factor as high as 37% relative to those using the general process.
