TOPIC: Dye-sensitized Solar Cell (DSSC) : Sel Surya Organik
Last Edit: 28 Sep 2010 20:07 by Silvia Widya Mardiana.
saya mau nanya mbak..sederhana aja..
berapa ya kira-kira harga per meter persegi dari DSSC ini?
mampu nggak kira-kira bersaing secara ekonomis dengan soalr cell konvensional lainnya?
saya kira faktor keekonomisan pembangkit listrik juga merupakan salah satu faktor yang sangat penting disamping kemampuannya menghasilkan listrik, kalau sulit bersaing dengan solar cell yang lain sepertinya DSSC akan sangat disayangkan mengingat teknologi ini saya rasa sangat menarik, karena memanfaatkan bahan yang terdapat di makhluk hidup untuk membuatnya...
oh ya, nanopori TiO2 nya didapat dari bahan non organik bukan y?
Sampai hari ini, DSSC masih dikembangkan pada tahapan scale-up dan produksi massal. Beberapa perusahaan sudah membeli lisensi dari EPFL Swiss selaku 'penemu' teknologi ini, sebut saja Solaronix dari Swiss, Dyesol dari Australia, 3G Solar dari Israel, dan G24 Innovation dari Inggris. Selain itu berbagai lembaga riset bergengsi juga terus berlomba meningkat efisiensi DSSC, seperti Frauhofer Institute dan juga Sharp. Selain efisiensi yang terus ditingkatkan, berbagai aspek seperti ketahanan terhadap lingkungan, kemampuan sekat permanen (hermeutic sealing), dan desain DSSC juga dikembangkan.
Adapun target harga yang dikejar adalah dibawah 1 USD/Wp, bandingkan dengan sel surya silikon yang kini berkisar 2 USD/Wp. Hal ini sangat berpeluang besar mengingat teknologi manufaktur DSSC tidak memerlukan clean-room yang mahal seperti halnya teknologi manufaktur sel surya silikon. Kemudian DSSC juga tidak menggunakan material silikon yang sangat dibutuhkan di industri elektronik, sehingga tidak terjadi persaingan stok permintaan.
Salah satu komponen penting pada DSSC adalah semikonduktor anorganik yang terbuat dari material metal oksida atau oksida logam, seperti Titanium dioksida (TiO2), Seng oksida (ZnO), yang mana struktur atau bentuknya dimodifikasi sehingga memiliki permukaan yang luas. Hingga saat ini, state of the art DSSC ini menggunakan TiO2 nanopartikel yang berukuran 10-20nm yang membentuk struktur menyerupai sponge atau mesopori.
