Branched Structures

ABSTRACTThiophene small novel branched structures have been proposed as candidates for dopant agents transporting holes-electron in organic solar cell (OSC). Low-band gap of these branched oligotiophene have been obtained to be used in organic solar cells. Two branched thiophene oligomers, a sexithienylene vinylene (E)-Bis-1,2-(5,5´´-Dimethyl-(2,2´:3´,2´´-terthiophene) vinylene, (BSTV) and octathienylene vinylene (BOTV) (E)-Bis-1,2-(5,5´´´-Dimethyl-(2,2´:5´,2´´:3´,2´´´-tetrathiophene) vinylene oligomers, have been synthesized and used as electron donor or dopant in a bulk heterojunction poly(3-hexylthiophene) (P3HT), /[6,6]-phenyl C61-butyric acid methylester (PCBM), Organic Photovoltaic cell.

The bulk quantum efficiency is the ratio of current generated in the active region of a bulk heterojunction to the light absorbed. Using this parameter, we can distinguish the location of recombination between the heterojunction and the peripheral layers of the organic photovoltaic cell.

Perkembangan teknologi OPV sangat menjanjikan sebagai sumber energi terbarukan dalam upaya mengurangi ketergantungan terhadap energi bahan bakar berasal dari fosil. Hal ini diperkuat karena ongkos fabrikasi perangkat fotovoltaik menggunakan material organik lebih murah dibandingkan dengan perangkat menggunakan material non-organik. Telaah ini membahas perkembangan organic photovoltaic cell (OPV) dari generasi pertama, kedua, dan ketiga. Berikutnya dibahas cara kerja OPV dan macam-macam OPV, seperti dye-sensitized solar cell (DSSC), double layer cell , bulk heterojunction cell, dan perovskite solar cell (PSC). Terakhir dibahas mengenai prospek yang dimiliki OPV. Dari perkembangan OPV terlihat bahwa efisiensi pada generasi pertama sebesar 6%. Efisiensi generasi kedua 17%. Sedangkan efisiensi generasi ketiga paling tinggi yaitu sekitar 26%. Kelemahan OPV adalah efisiensinya rendah dan umur pakainya singkat. Sifat OPV ringan dan lentur sehingga penerapannya lebih luas.
