Abstract

ABSTRAK Elektroda balik berbasis platina telah banyak digunakan dalam dye-sensitized solar cell (DSSC). Beberapa riset dilakukan untuk memodifikasi elektroda balik berbasis platina diantaranya dengan mengubah teknik deposisi, komposit paduan logam, modifikasi permukaan, dll. Riset ini bertujuan untuk menginvestigasi pengaruh perlakuan permukaan elektroda balik platina menggunakan larutan prekursor nickel (II) chloride (NiCl2), copper (II) chloride (CuCl2), dan copper (I) thiocyanate (CuSCN) dengan teknik sederhana yaitu spin-coating. Elektroda balik platina dibuat menggunakan teknik screen-printing kemudian dilakukan proses deposisi larutan prekursor dan dipanaskan pada suhu 105°C. Efisiensi Pt/CuSCN dan Pt/CuCl2 meningkat menjadi 5.25% dan 5.14%, dibandingkan dengan kontrol Pt (4.58%). Meskipun Pt/CuSCN memiliki konduktivitas yang rendah dari hasil karakterisasi electrochemical impedance spectroscopy (EIS). Nilai JSC nya mencapai 12.73 mA/cm², lebih tinggi dibandingkan dengan Pt (11.9 mA/cm²). Sementara itu, efisiensi Pt/NiCl2 turun menjadi 4.47% dikarenakan rendahnya VOC and JSC. Sebagai hasil dari riset ini, perlakuan permukaan pada elektroda balik platina menggunakan CuSCN dan CuCl2 memiliki keterlibatan dalam peningkatan performa DSSC. Kata kunci: dye-sensitized solar cell, counter electrode, surface modification ABSTRACT The platinum-based counter electrode (Pt-CE) has been widely used in dye-sensitized solar cells (DSSC). Several research of modifying platinum-counter electrodes such as altering the deposition techniques, composite metal alloy, surface modification, etc. This research aims to investigate the effect of surface treatment on platinum-based counter electrodes using a solution precursor of nickel (II) chloride (NiCl2), copper (II) chloride (CuCl2), and copper (I) thiocyanate (CuSCN) with a simple technique of spin-coating. Platinum-based counter electrode was prepared using a screen-printing technique and afterward, the deposition of solution precursors then heated at 105°C. Pt/CuSCN and Pt/CuCl2 increased efficiency of 5.25% and 5.14% respectively, compared with the control Pt (4.58%). Even Pt/CuSCN is less conductive by electrochemical impedance spectroscopy characterization. The JSC reaches 12.73 mA/cm², higher than Pt (11.9 mA/cm²). Meanwhile, the efficiency of Pt/NiCl2 decreases to 4.47% due to the lower VOC and JSC. As a result, this Pt-CE surface treatment using CuSCN and CuCl2 has implications to raise the DSSC’s performance. Keywords: dye-sensitized solar cell, counter electrode, surface modification
