Abstract
This work focus on the fabrication and performance characterization of hybrid (ZnO nanorod/P3HT:PCBM) and organic solar cell (P3HT:PCBM). For hybrid solar cell, material such as regioregular 3 - hexylthiophene - 2 , 5 – diyl (P3HT) (donor material), zinc oxide (ZnO) (acceptor material) and fullerene [ 6,6 ] phenyl C61 acid butyric methyl ester (PCBM) (acceptor material) was used. Synthesis by microwave irradiation method was to get ZnO nanorod. Parameters such as time and irradiation power cause different length and diameter of ZnO nanorod growth, but for substrate with/without PCBM layer yield different efficiency. The combination layer of ZnO nanorod/P3HT:PCBM have highest efficiency of 0.39% (power irradiation 550W, time for 30 mins and with addition of PCBM) compared to the combination layer of ZnO/P3HT with efficiency of only 0.17% (power irradiation 550W, time for 30 mins and without addition of PCBM). After that, for organic solar cell material such as P3HT (donor material), PCBM (acceptor material) and Poly(3,4-ethylenedioxythiophene) poly (styrenesulfonate) (PEDOT:PSS) (buffer layer) was used. Oxidative polymerization synthesis method was used to get P3HT material. Parameters such as temperature, ratio of PCBM and with/without PEDOT:PSS layer yield different efficiency. The combination layer of PEDOT:PSS/P3HT:PCM have highest efficiency of 2.44% (ratio of PCBM 1:4, temperature 140oC and with addition layer of PEDOT:PSS) compared to the
combination layer of P3HT:PCBM with efficiency of only 1.05% (ratio of PCBM 1:4, temperature 140oC and without addition layer of PEDOT:PSS). From these work, it can be concluded that organic solar cell have higher efficiency compared to hybrid solar cell.
