摘要

本论文探讨了铜锌锡硫化物(CZTS)和镍(Ni)-CZTS 太阳能电池的光学、结构、成分和电学特性。研究人员采用微波合成法合成了铜锌锡硫化物和掺镍铜锌锡硫化物粉末。X 射线衍射和拉曼散射光谱证实了 CZTS 和 Ni-CZTS 的单相钾长石晶体结构。薄膜在紫外-可见光范围内的光学吸收光谱显示出超过 \(10^{4} {text\{cm}}^{ - 1}\) 的强吸收系数。由于掺杂了镍,CZTS 的光带隙能从 1.5 eV 下降到了 1.41 eV。在这两种样品中都检测到了正霍尔系数,证实了 p 型导电性的存在。本研究旨在确定掺入 Ni-CZTS 对 FTO/CZTS/CdS/ZnO/Ag 太阳能电池性能的影响。在 CZTS 和 CdS 之间引入 Ni-CZTS 可实现最佳排列和更高的效率。5%的镍掺杂浓度是最佳掺杂浓度,其结果是\(J_{sc} = 32.5\;{text{mA}}/{text{cm}}^{2}\),\(V_{{text{oc}}}} = 0.541\;{\text{V}}\), \({\text{FF}} = 31%/),效率为5.4%。

Ni doping in CZTS solar cells: a path to enhanced photovoltaic performance

The present communication explores the optical, structural, compositional, and electrical properties of Copper Zinc Tin Sulfide (CZTS) and Nickel (Ni)-CZTS solar cells. A microwave-based synthesis method has been employed to synthesize CZTS and Ni-doped CZTS powders. X-ray diffraction and Raman scattering spectroscopy have confirmed the monophase kesterite crystal structure of CZTS and Ni-CZTS. Optical absorption spectroscopy of films in the UV–Visible range displays a strong absorption coefficient of more than \(10^{4} {\text{cm}}^{ - 1}\). In response to Ni doping, the optical band gap energy of CZTS decreased to 1.41 eV from 1.5 eV. In both samples, positive Hall coefficients were detected, confirming the presence of p-type conductivity. This study aims to determine the effects of Ni-CZTS incorporation on the performance of FTO/CZTS/CdS/ZnO/Ag solar cells. The introduction of Ni-CZTS between CZTS and CdS resulted in optimum alignment and higher efficiency. 5% Ni doping concentration is found to be the optimum doping concentration, resulting in \(J_{sc} = 32.5\;{\text{mA}}/{\text{cm}}^{2}\), \(V_{{{\text{oc}}}} = 0.541\;{\text{V}}\), \({\text{FF}} = 31\%\) and the efficiency is 5.4%.
