Polymer Solar Cell

Solar cells (SCs) employing freshly synthesized home-made regio-regular poly(3-hexylthiophene) (RR-P3HT) and PCBM yielded nearly two fold increase of short circuit current, compared with the devices consisting of commercial RR-P3HT. The filling factor (FF) on the other hand decreased significantly resulting in the overall efficiency of 4{\%} for the device with commercial PHT from ADS. However, improving the serial resistance of the device can lead to much higher efficiency. The ideal homogenization of P3HT/PCBM solution and the optimal device heat-treatment [1] were used with the fresh home-made polymer to achieve the good phase separation of PCBM and RR-P3HT into a bi-continuous network structure. The best concentration of PCBM was found rather low; only 54 wt{\%} with respect to RR-P3HT in Toluene contrary to reported high 400 wt{\%} to PPV in 1,2 Dichlorobenzene.
