Investigations on the Synthesis, Optical and Electrical Properties of TiO2 Thin Films by Chemical Bath Deposition (CBD) method

“…It is also an excellent electrode material that can be used for the conversion of light energy into electrical energy because of its semiconductor properties. Its wide applications such as supercapacitors, dye-sensitized solar cells, quantum-dot-sensitized solar cells, lithium ion batteries, photoelectrolysis, water splitting, biosensors, photochromic devices, self-cleaning, and extremely thin absorber (ETA) solar cells have already been explored [8][9][10][11][12][13][14][15][16][17] . TiO 2 films can be synthesized by many chemical and physical deposition techniques, such as chemical vapor deposition, spin coating or spin casting, atomic layer deposition, molecular beam epitaxy, sputtering, cathodic arc deposition, electrospray deposition, sol-gel process 18 .…”

Influence of electronic structures of doped TiO2on their photocatalysis

“…Titania, as the most studied photocatalyst is still being intensively researched and has become quite well understood experimentally and theoretically [11][12][13]. TiO 2 as a durable photocatalyst can be used to solve a variety of problems in environmental interest, such as destruction of microorganisms in forms of bacteria [14][15][16][17][18][19] and viruses [20], inactivation of cancer cells [21,22], and photosplitting of water to produce hydrogen gas [2,[23][24][25][26][27][28]. The photocatalytic process decomposes organic compounds and bacteria into carbon dioxide and water to clean the water and the air [12].…”
