Abstract
Penelitian sebelumnya menunjukkan bahwa fraksi coreshell SiO2@Au@TiO2 mempengaruhi performa DSSC. Modifikasi fotoanoda DSSC dapat dilakukan dengan menambahkan core-shell SiO2@Au@TiO2. Fraksi Au pada core-shell divariasikan juga dengan variasi larutan Au pada sebesar 60ml 90ml dan 120ml. Fraksi core-shell SiO2@Au@TiO2 terhadap pasta TiO2 divariasikan, yakni 0,5%, 1% dan 5%. Dari hasil pengujian yang telah dilakukan menunjukkan bahwa modifikasi core-shell SiO2@Au@TiO2 dengan penambahan larutan Au serta variasi fraksi core-shell terhadap pasta TiO2 mempengaruhi besar nilai efisiensi dari DSSC, sedangkan penambahan fraksi Au seharusnya diikuti dengan penambahan APTMS. DSSC yang memiliki efisiensi paling tinggi ialah DSSC dengan core-shell SiO2@Au@TiO2 dengan penambahan larutan Au sebesar 60 ml dan fraksi core-shell terhadap pasta TiO2 0,5% dengan efisiensi sebesar 0,557% dan peningkatan sebesar 40% terhadap DSSC dengan pasta TiO2 murni.

Previous studies have shown that the core-shell SiO2@Au@TiO2 fraction influences DSSC’s performance. Modification on DSSC photoanode was undertaken by adding core-shell of SiO2@Au@TiO2. The amount of Au in the core-shell was varied by changing the Au solutions of 60, 90 and 120 ml. On the other hand, the amount of core-shell particles within TiO2 was varied, too i.e. 0,5%, 1% and 5%. The effect of Au addition on core-shell nanoparticles depends largerly on the amount of APTMS in order to ensure that Au nanoparticles attach properly on SiO2 surface. On the other hand, the amount of core-shell in TiO2 photoanode causes the increase in DSSC’s efficiency, i.e. o,557% and the net efficiency increment towards pristine TiO2 photoanode is 40%.
