We demonstrate green synthesis of TiO2 nanopartieles (Nps) derived from automobile paint sludge (APG) and its application in the development of sustainable and solution processable polymer solar cells (PSCs). The APG contains TiO2 > 35% of its weight with several surfactants, organic polymers and similar to 2 to 10 % inorganic matter depending on the type of paints used. The TiO2 is generally present as micro sized particles in the APG which on hydrothermal treatment transform into nano sized particles. These organic matter is thermally extracted by a specially designed reaction vessel, where as the inorganic impurities are removed by repeated washing with dilute acids and bases. The TiO2 Nps are characterized by SEM imaging, EDX analysis, powder XRD, TC/DTA and FTIR, spectroscopy techniques. The TiO2 Nps are re-suspended in methanol for application in PSCs as an efficient electron transport layer. The TiO2 layer was spin coated on bulk hetero junction active layer of low band gap donor polymers P3HT with PCBM as electron acceptor. The performance of the TiO2 Nps is analyzed by fabricating devices in ITO/PEDOT:PSS/active layer/TiO2/Al configuration. The present work has implication for ultra low cost and sustainable PSCs with advantage of recycling of a highly hazardous industrial waste.
