Controlled synthesis and characteristics of antireflection coatings of TiO2 produced from a organometallic colloid

► Titanium dioxide antireflection coating was made by a less used titanium colloidal precursor solution. ► Sol-gel spin-coating process was used to make thin films on silicon substrates. ► Various process parameters have been studied and their effect on physical, structural and optical properties was investigated. ► Application of the coating on silicon solar cells showed an enhancement more than 20% in Jsc in comparison to the cell devoid of the coating.
