제목 | Characterization of Flexible CZTSSe Thin Film Solar Cells Grown by Sputtering Process |
초록 | Thin-film solar cells on flexible substrates have an advantage to achieve the grid parity by reduction of manufacturing costs due to their high power conversion efficiency, low material usage and low deposition cost on large areas. In addition, flexible substrates could further reduce the manufacturing costs due to their compatibility with roll-to-roll industrial processes. In this study, we fabricated flexible CZTSSe solar cell with 6.48 % efficiency on Mo foil substrate. Mo foil substrate was soaked in a NaOH solution with 0.5 wt % at 40 oC for 20 min. CZTSSe precursor was deposited on the Mo foil substrate using sputtering process with a stacking order of Cu/Sn/Zn/Mo. The characteristics of flexible CZTSe solar cell showed the Voc of 0.404 V, Jsc of 34.80 mA/cm2, fill factor of 38.58 %, efficiency of 6.48 %.
