Sensitized Solar Cells

<p><em>Dye sensitized solar cells</em> (DSSCs) merupakan teknologi alternatif fotovoltaik yang menguntungkan. DSSCs menunjukkan harga yang murah, efisiensi yang tinggi dan proses pembuatan yang sederhana. Dalam aplikasi DSSCs, fotoanoda memiliki peranan yang penting untuk mengumpulkan elektron-elektron yang tereksitasi dan dye berfungsi untuk menyalurkan cahaya elektron-elektron ke <em>transparent conducting film</em> (TCF). Fotoanoda mempunyai <em>band gap</em> yang lebar pada semikonduktor logam oksida (contoh: <em>zinc oxide</em> (ZnO) dan <em>titanium dioxide</em> (TiO<sub>2</sub>)) yang dilapiskan pada TCF. Counter electrode (CE) adalah salah satu komponen yang penting dalam proses kerja DSSCs. CE digunakan sebagai mediator untuk membangkitkan <em>sensitizer</em> setelah masuknya elektron. Bahan CE yang ideal harus mempunyai resistansi yang rendah, biaya produksi yang murah, konduktivitas listrik yang tinggi, aktivitas elektrokatalitik yang bagus dan stabilitas yang tinggi. Bahan-bahan CE yang umum digunakan untuk aplikasi DSSCs yaitu seperti platina (Pt), karbon, <em>carbon nanotubes</em> (CNTs), grafin dan polimer konduktif. Review ini dikembangkan untuk mempelajari sifat-sifat bahan fotoanoda dan CE yang bagus untuk aplikasi DSSCs. Review ini juga digunakan untuk memberikan informasi untuk perkembangan bahan-bahan fotoanoda dan CE pada penelitian selanjutnya dalam aplikasi DSSCs. Dalam review ini, pengaruh bahan-bahan yang digunakan untuk fotoanoda dan CE dalam aplikasi DSSCs didiskusikan.</p>

Sensitized Solar Cells

Dye sensitized solar cells (DSSCs) offer many advantages in comparison to their Si-based counterparts, including lower cost of raw materials, faster manufacturing time, and the ability to be integrated with flexible substrates. Although many advances have been made in DSSC fabrication over recent years, their efficiency remains lower than commercially available Si photovoltaic cells. Here we report improved efficiency of TiO2/anthocyanin dye solar cell using aligned arrays of carbon nanotubes (CNTs) as a counter electrode. Dense vertically oriented CNT arrays are grown directly on the counter electrode using microwave plasma chemical vapor deposition and a tri-layer (Ti/Al/Fe) catalyst. The resulting arrays are 30 micrometers in height and have a number density of approximately five hundred million per square millimeter. By directly growing the CNTs on the counter electrode substrate, electrical interface conductance is enhanced. The performance of both as-grown and N-doped (using a nitrogen plasma) CNT arrays is reported. The fabricated DSSCs are tested under AM1.5 light. Increased short circuit current is observed in comparison to graphite and Pt counter electrodes. We attribute this improvement to the large surface area created by the 3D structure of the arrays in comparison to the planar geometry of the graphite and Pt electrodes as well as the excellent electrical properties of the CNTs.
