| Abstract | ||
| Abstract Due to their lighter weight, conjugated (semiconducting) polymer cells have a potential of displacing conventional silicon cells. The most studied conjugated polymer solar cell is the bulk heterojunction cell. Here, the active layer is made up of a mixture of the conjugated polymer donor and the C60 based - fullerene acceptor. The efficiency of the cell is determined, using a solar simulator and the AM1.5G standards, after determining existence of an open circuit voltage (Voc) and short circuit current. Using Design of Experiments (DOE), Voc has been maximized. The variables considered in the DOE were solvent type, number of layers of PEDOT:PSS and polymer/fullerene mix, as well as spin-coating times and speeds, and annealing time, temperature and applications per cell layer | ||
