Abstract
In this work, nanoporous $TiO_2$ powder was fabricated using Ketjen black, and applied in photovoltaic device based on the Dye-sensitized Solar Cells (DSCs). $TiO_2$ powder was fabricated using Ti-isopropoxide and 2-propanol by sol-gel combustion method. For added $0{\sim}2g$ variable of Ketjen black, characteristic of porosity, size of particle and crystallite of obtained $TiO_2$ nano powder was investigated. The photovoltaic efficiency of the prepared DSCs was measured using $TiO_2$ film which prepared on each different heat treatment temperature($100^{\circ}C{\sim}600^{\circ}C$) with paste of $TiO_2$ powder. The porosity and size in particle of $TiO_2$ powder made with Ketjen black Ig was influenced significantly effect to DSCs characteristic. Heat treatment at $500^{\circ}C$ makes the better photovoltaic efficiency which around 6.11%($J_{sc}=13.35mA/cm^2$, $V_{oc}=0.73V$, ff=0.63). The sol-gel combustion method was useful to DSCs fabrication.
