Preparation of TiO2 films by layer-by-layer assembly and their application in solar cell

Preparation of thermally stable anatase TiO2 photocatalyst from TiOF2 precursor and its photocatalytic activity

“…In recent years, in order to solve the increasingly serious environmental pollution problems, heterogeneous semiconductor photocatalysis gradually becomes a popular technique for its potential to control aqueous contaminates or air pollutants [1][2][3][4][5][6][7]. Among various oxide semiconductor photocatalysts, titania has attracted increasing attention due to its biological and chemical inertness, strong photo oxidization power, cost effectiveness, and long-term stability against photo and chemical corrosion [1,[8][9][10][11][12][13][14].…”

Structural and nano-composite features of TiO2–Al2O3 powders prepared by sol–gel method

“…Nanocrystalline titanium dioxide has a widespread range of new applications as important material in photocatalyst [1], solar cell [2], chemical and marine industries [3] and humidity sensors [4]. Alumina has numerous applications ranging from catalysis [5,6] to optics [7], electronics [8] and biomedicine [9,10].…”

Efficiency enhancement of inverted organic photovoltaic cells due to an embedded Ce-doped ZnO electron transport layer synthesized by using a sol–gel process

“…Inverted OPV cells can overcome this degradation problem. The electron transport layer (ETL) of the inverted OPV cell uses ZnO [8,9], TiO x [10,11], or Al 2 O 3 thin films [12,13]. ZnO thin films have emerged as an excellent candidate for the ETL in the inverted OPV cells due to their particular features of high electron mobility, good environmental stability, high optical transmittance in the visible range [14,15], wide band gap of 3.37 eV, and large exciton binding energy of 60 meV [16][17][18].…”
