The synthesized materials were characterized by X-ray diffraction, scanning electron microscopy, pore diameter, pore volume and surface area. The dye-sensitized solar cells were fabricated using the synthesized materials and characterized for incident photon to current conversion efficiency, photocurrent density to photo voltage measurement and electrochemical impedance analysis. Among the studied materials, TiO2 synthesized by sol-gel method displayed highest photon to current conversion of 76.8% and a maximum solar cell efficiency of 7.85% with Jsc of 14.75mA/cm², Voc of 0.76V and FF of 0.7. This is the first study to report a high power conversion efficiency of DSSC using a sol-gel synthesized titania and its comparison with other two synthesized materials. The high power conversion efficiency of the solar cell using TiO2 synthesized by sol-gel method is attributed to its characteristic properties such high surface area, larger pore diameter and larger pore volume and highest dye loading capacity.1 aUmale, Sanjivani, V.1 aTambat, Sneha, N.1 aVediappan, Sudhakar1 aSontakke, Sharad, M.1 aKrishnamoorthy, Kothandam  uhttp://library.ncl.res.in/content/fabrication-characterization-and-comparison-dssc-using-anatase-tio-2-synthesized-various01648nas a2200229   4500008004100000022001400041245006600055210006600121260000800187300001200195490000800207520093000215653002501145653003001170653000901200100002101209700001701230700002501247700002301272700002601295856009701321       2019                        eng d  a0025-540800aImproved efficiency of DSSC using combustion synthesized TiO20 aImproved efficiency of DSSC using combustion synthesized TiO2  cJAN  a222-2260 v1093 a<p>Combustion synthesis method is an economic, one step and an effective method for the synthesis of nanomaterials. In this work, titanium dioxide nanoparticles were synthesized by combustion method. The synthesized material was characterized by XRD, SEM and BET. Dye sensitized solar cell was fabricated using the synthesized material and its performance was compared with the solar cell fabricated using commercial TiO2. In order to evaluate the photovoltaic performance of DSSCs, photocurrent density to photovoltage (J-V) characteristic and electrochemical impedance spectroscopy (EIS) measurements were carried out. The DSSC fabricated using combustion synthesized and commercial TiO2 exhibited a power conversion efficiency of 6.11% and 6.62%, respectively. Combustion synthesized TiO2 which displayed similar efficiency to that of commercial material is least studied in the literature for solar cell applications.</p>10aCombustion synthesis10aDye sensitized solar cell10aTiO21 aUmale, Sanjivani1 aSudhakar, V.1 aSontakke, Sharad, M.1 aKrishnamoorthy, K.1 aPandit, Aniruddha, B.  uhttp://library.ncl.res.in/content/improved-efficiency-dssc-using-combustion-synthesized-tio2
