Notes: --- - "Effect of spray rate on structural, optical and electrical properties of spray pyrolysed Cu2ZnSnS4 (CZTS) thin films was investigated. We deposited films by varying spray rate from 2 ml/min to 10 ml/min in steps of 2 ml/min. For very low and high spray rates presence of secondary phases could be observed while for the films prepared at a spray rate of 6 ml/min were devoid of secondary phases. As spray rate increases band gap decreased. Samples prepared at 6 ml/min had optimum band gap of 1.5 eV. All the samples were observed to be p-type. Resistivity values increased steadily up to 6 ml/min and then slightly decreased. From the present work, CZTS films prepared at a spray rate of 6 ml/min is found to be ideal for absorber layer in solar cell. \xC2\xA9 2014 AIP Publishing LLC." - "<p>Export Date: 11 February 2015</p>"
