Abstract

Dye-sensitized solar cell (DSSC) memiliki keunggulan yaitu mudah dalam manufaktur dibandingkan sel surya berbasis silikon. DSSC tidak mengandung racun dan bisa dirancang di suhu ruangan. Peningkatan efisiensi DSSC terus dikembangkan dan hingga saat ini efisiensi maksimal yang berhasil didapatkan sekitar 11%.Pada penelitianini fabrikasi DSSC dilakukan dengan metode ultrasonic atomizer untuk pelapisan dye organikpadaTiO2. Substrat yang digunakan merupakan jenis Flourine-doped Tin Oxide (FTO) yang digunakan sebagai tempat mengalirnya muatan. TiO2 sebagai jalur loncatan elektron dan pengikat molekul dye. Dye digunakan untuk menyerap foton dan membantu menghasilkan listrik. Dye organik yang digunakan adalah daun pucuk merah. Pasangan redoks iodine/triiodide digunakan untuk menghasilkan elektrolit. Sedangkan karbon digunakan sebagai counter-electrode pada DSSC. Lapisan TiO2, dye organik, elektrolit, dan counter-electrode disusun serta dikombinasikan dengan struktur berlapis sebagai lapisan donor-aseptor. Pengujian sel didapatkan bahwa DSSC yang terlapis dye memiliki nilai tegangan open circuit sebesar 105,6 mV, arus short circuit 4,6 μA dan daya maksimal 122,95 nW. Nilai DSSC terlapis dye lebih tinggi dibandingkan dengan DSSC yang tidak terlapisi dye. Penyerapan cahaya efektif dalam DSSC yang terlapisi dye yaitu cahaya warna biru. ======================================================================== Dye-sensitized solar cell (DSSC) has the advantage of being easy to manufacture compared to silicon-based solar cells. DSSC does not contain toxins and can be designed at room temperature. The efficiency improvement of DSSC continues to be developed and to date the maximum efficiency that has been achieved is around 11%. In this study DSSC fabrication was carried out by ultrasonic atomizer method for coating organic dye on TiO2. The substrate used is a type of Flourine-doped Tin Oxide (FTO) which is used as a place to load the contents. TiO2 is an electron jumping path and a dye molecule binder. Dye is used to absorb photons and help produce electricity. Organic dye used is Syzygium Oleana leaves. The redox iodine / triiodide pair is used to produce electrolytes. While carbon is used as a counter-electrode in DSSC. TiO2 layers, organic dyes, electrolytes, and counter-electrodes are arranged and combined with layered structures as donor-acceptor layers. Cell testing found that the DSSC which is dye-coated has an open circuit voltage value of 105.6 mV, 4.6 μA short circuit current and a maximum power of 122.95 nW. DSSC's dye-coated value is higher than DSSC which is not dye-coated. Light absorption is effective in DSSC coated with dye that is blue light.
