Organic molecules based photovoltaic cells were fabricated in an open laboratory conditions without the use of glove box or clean room. Conducting
polymers such as P3HT and PCBM were used as a photo-active layer of the
devices. We found significant difference in the performance of the devices
by employing two laboratory conditions of the polymer solutions. Enhanced
current density has been observed from P3HT/PCBM bulkheterojunction
solar cell after diluting a well sonicated polymers solution with fresh chloroform solvent. As the result of such current surge in the devices the efficiency
rose to more than double compared to those devices without dilution of the
P3HT/PCBM solution. An average power conversion efficiency of 4.5% was
then recorded from the new preparation condition. This is an encouraging
development toward achieving low cost organic photovoltaic devices. / Thesis (M.Sc.)-University of KwaZulu-Natal, Pietermaritzburg, 2013.
