Kesterite (Cu₂ZnSnS₄) thin films are spray deposited under 0 V and 1500 V DC voltages and then treated with N₂+H₂S(5%) environment at 500 °C for 1 h for sulphurisation. The improvement in different properties like structural, optical, morphological and electrical occur in the kesterite films deposited under the electric field. The activation energy is also reduced for these films, after applying the DC voltage during the spray deposition. These improvements resulted in the enhancement of the catalytic properties of kesterite films for use as the counter electrodes in dye sensitized solar cells. Dye sensitized solar cell using the kesterite film as a counter electrode deposit under the applied voltage of 1500 V exhibits the power conversion efficiency of 4.93%, which is higher than that for the kesterite film deposit under the applied voltage = 0 V (3.77%). The power conversion efficiency of sulphurised kesterite films deposit at 0 V and 1500 V yield further improvement in the power conversion efficiency (6.58 and 7.67%, respectively).

在0 V和1500 V DC电压下喷涂Kesterite（Cu ₂ ZnSnS ₄）薄膜，然后用N ₂ + H _2处理在500°C的S（5％）环境中硫化1小时。在电场下沉积的硅藻土薄膜中，结构，光学，形态和电学性质的不同性质都有所改善。在喷涂过程中施加直流电压后，这些薄膜的活化能也会降低。这些改进导致增强了用作染料敏化太阳能电池中的对电极的镁橄榄石薄膜的催化性能。在施加电压1500 V的情况下，将钾盐沸石膜作为反电极沉积物的染料敏化太阳能电池的功率转换效率为4.93％，高于在施加电压= 0 V时的钾盐沸石膜沉积物的功率转换效率（3.77％） 。
