Abstract In this work, we present the fabrication process and analyze optical properties of carbon nanodots (C-dots) from rice powder taken Kupang regency, East Nusa Tenggara Province. The was annealed at 400oC for 30 minutes to obtain a black powder. This sample (0.5 gram, 3 mL ethanol) sonicated an hour, ethanol (10 mL) added again centrifugation 1000 rpm 20 minutes. Furthermore, solution fil...

Although the power conversion efficiencies (PCEs) of bulk heterojunction (BHJ) organic solar cells (OSCs) continue increasing toward 20% milestone, important factors for industrial application are mostly neglected, such as photostability and cost potential. Single-component OSCs (SCOSCs) employing materials with chemically bonded donor acceptor moieties successfully overcome immiscibility betwe...
