Abstract
Penelitian sebelumnya menunjukkan bahwa diameter AuNP akan mempengaruhi efek Localized Surface Plasmon Resonance (LSPR). Variasi diameter AuNP dapat dilakukan dengan menambahkan konsentrasi dari Al(NO3)3 dan NaCl masing – masing sebesar masing- masing 0,25 mM, 0,5 mM, 0,75 mM, 1 mM dan 12,5 mM, 25 mM, 37,5 mM 50 mM. Dari hasil pengujian yang telah dilakukan menunjukan bahwa penambahan Al(NO3)3 dan NaCl pada core-shell Au@TiO2 akan mengakibatkan terjadinya pertumbuhan diameter AuNP yang digunakan sebagai core. Fabrikasi DSSC dengan penambahan core-shell Au@TiO2 dengan variasi diameter AuNP dari diameter sekitar 34,62 nm – 139,5 nm. DSSC yang memiliki efisiensi tertinggi yaitu dengan penambahan 1mM Al(NO3)3, dengan diameter AuNP sebesar 139,5 nm dan efisiensi 0,0031%. Serta memiliki rentang IPCE paling luas mulai dari 305 nm hingga 690 nm.

Previous research has shown that the particle size of AuNP affects the LSPR (Localized Surface Plasmon Resonance). The size of AuNP is controlled by fast addition of Al(NO3)3 and NaCl. DSSC with core-shell Au@TiO2 addition was prepared with various number of AuNP’s size within range of 34.62 nm – 139.5 nm. Size variation was because of the Al(NO3)3 and NaCl concentration from 0,25 mM, 0.5 mM, 0.75 mM, 1 mM for Al(NO3)3 sampels and 12.5 mM, 25 mM NaCl, 37.5 mM NaCl, 50 mM for NaCl sampels. Based on the IV test, the highest efficiency produced by the sampel with 1 mM Al(NO3)3 addition, the result is 0.0031% efficiency with 139.8 nm diameter of AuNP and also has the widest photons activation range around 305 nm up to 690 nm.
