In this work, the power conversion efficiency (PCE) of bulk heterojunction organic solar cell is improved by adding PEG (polyethylene glycol) in the solution of P3HT and PCBM blend. The short circuit current and fill factor are increased by adding PEG with the molecular weight of 300, whereas the open circuit voltage is not changed. On the other hand, PCE becomes worse by adding PEG with the molecular...
