Abstract

Tembaga (II) oksida (CuO) merupakan salah satu material logam oksida yang cukup menarik perhatian dari segi sifat material berskala nano dan pengaplikasiannya pada sel surya. Pada penelitian ini telah difabrikasi DSSC berbasis semikonduktor tipe p menggunakan CuO dengan variasi morfologi berupa CuO nanopartikel sintesis, CuO nanorod, dan satu sebagai pembanding yaitu CuO nanopartikel komersil. DSSC berbasis semikonduktor tipe p ini berpotensi untuk membuka perkembangan selanjutnya mengenai DSSC tandem (tipe p-n). CuO nanorod dan nanopartikel berhasil disintesis menggunakan metode hidrotermal dengan morfologi nanopartikel menggunakan prekursor Cu(SO)4 dan amonium pada temperatur 700ºC. Karakterisasi XRD, UV-Vis, dan SEM bertujuan untuk mengetahui struktur/kristalinitas, absorbansi/sifat optik, dan morfologi CuO sebagai fotokatoda. Salah satu hasil karakterisasi XRD menunjukkan nilai dislokasi (δ) terbesar ditunjukkan oleh sampel CuO nanorod 2,10583.10-3 nm2. Uji UV-Vis menunjukkan seluruh sampel memiliki puncak absorbansi 397 nm. Sedangkan ukuran partikel yang diperoleh dari uji SEM berkisar antara 166,61 nm hingga 396,725 nm, dimana CuO sintesis 450ºC memiliki agregat terbanyak. Karakterisasi Fotokatoda dengan pengujian I-V di bawah sinar matahari langsung menghasilkan efisiensi terbaik DSSC Tipe p CuO sintesis 700oC sebesar 0.0001668% dengan Voc sebesar 0,1316 V, Jsc sebesar 0,0036 mA/cm2, dan fill factor (FF) sebesar 0,27153. ====================================================================================================== Cupric oxide (CuO) is one of the metal oxide materials that is interesting in terms of the properties of nanoscale materials and its application to solar cells. In this research, it has been successfully fabricated a p-type semiconductor-based DSSC using various CuO nanoparticle morphologies, i.e. as-synthesized, nanorods, and commercially available ones. The p-type semiconductor-based DSSC has potential to be fabricated as tandem DSSC (type p-n) in the future. CuO nanorod and nanoparticles were successfully synthesized using the hydrothermal method using Cu(SO)4 precursor and ammonium at 700ºC. The XRD, UV-Vis, and SEM characterizations aimed to determine the structure/crystallinity, absorbance/optical properties, and morphology of CuO as a photocathode, respectively. XRD results indicated that CuO in the form of nanorod has the largest dislocation (δ) density, i.e., 2,10583.10-3 nm2. All samples had absorbance peaks at the wavelength of 397 nm. On the other hand, particle size obtained from SEM was in the range of 166,61 nm to 396,725 nm, with the as-synthesized at 450°C has the most aggregate. The photocathode characterization through I-V curve measurement under the direct sun indicated that the highest efficiency produced by p-type DSSC with CuO synthesized at 700ºC, namely 0,0001668% with Voc of 0,1316 V, Jsc of 0,0036 mA/cm2, and fill factor (FF) of 0,27153.
