مطالعه خواص فوتورسانايي و ترموالكتريكي لايه هاي نازك سه تايي SnS : Zn به روش اسپري پايروليزيز

Study of photo conductivity and thermo-electrical properties of ternary thin films (SnS:Zn) by spray pyrolysis technique

در اين تحقيق، لايه هاي نازك سولفيد قلع با ناخالصي روي به روش اسپري پايروليزيز بر روي بسترهاي شيشه اي تهيه شده است كه تراز ناخالصي براي روي از % Zn ] / [ Sys ] = 5 - 30 at در محلول تغيير داده شد. اثر حضور ناخالصي ZF بر روي خواص الكتريكي، اپتيكي و ساختاري لايه هاي نازك SnS : Zn بررسي شد. نتايج اين بررسي ها نشان ميدهد كه با افزودن ناخالصي ZR1 تا ٪30تمي ساختار لايه ها بس بلوري هستند و با افزايش ناخالصي ضريب سيبك افزايش پيدا كرد.

In this research, we prepared thin films of tin-sulfide by using spray pyrolysis technique deposited on glass substrate which are doped by zinc as impurity. The structural and thermo-electrical properties of films were investigated using Xray diffraction (XRD) and seebeck effect measurements. Photoconductivity properties of films were measured under illumination with a fixed intensity (4200 LUX), in constant distance. The results of this study showed that the optimum solution concentration for preparation of ternary thin films (SnS:Zn) with high photoconductivity and thermo-electrical properties are 5% and 30%, respectively
