Fabrication of Ag doped CZTSSe Chalcogenide Solar Cells by Various Stacking Orders |
| 초록 |
Silver(Ag) doping process in CZTSSe chalcogenide thin film solar cells have been studied and can be promised solution for Voc deficit because of Cu-Zn disorder since they are isoelectronic elements. Sufficient amount of Ag alloying on CZTSSe surface can be n-type semiconductor which is appropriate type-inverted junction with CdS buffer layer, whereas undoped CZTSSe has a strong p-type defects so the type-inversion is difficult to be formed at the CZTSSe/CdS interface. To compare the reaction mechanisms and solar cells performances, we have deposited various stacking order of Ag/Sn/Cu/Zn/Mo, Sn/Ag/Cu/Zn/Mo, Sn/Cu/Ag/Zn/Mo, Sn/Cu/Zn/Ag/Mo and Sn/Cu/Zn/Mo on soda-lime glasses and Mo foils by thermal evaporation for 5 nm of Ag layer and DC magnetron sputtering process for Zn, Cu and Sn layers. After fabrication of the solar cells, we have measured the performances by J-V and EQE and further analyzed by XRD, FESEM, HRTEM, TOF-SIMS for the analysis of reaction mechanisms. |
