Organic-inorganic hybrid electronics can combine the advantages offered by either organic or inorganic materials individually and thereby exhibit enhanced performance. In this work, we present 6,13-bis (triisopropylsilylethynyl)-Pentacene solution-processed planar type organic/inorganic hybrid devices with trench isolated gold electrodes. Devices with organic channel dimensions of 100 nm - 260 nm were fabricated by UV lithography and drop-coating using a TIPS-pentacene solution. The electrical characterization of such devices was carried out with and without illumination to check for possible applications of such devices in light sensing. Three different laser lines (325 nm, 514.7 nm, and 632.8 nm) were used for illuminating the sample. It was observed that the photocurrent and photo-switching response time increases with the photon energy. Devices with smaller channel length showed higher photocurrents and faster switching behaviour. This observation is in agreement with the presence of space charge limited currents as a main transport mechanism.
