研究目的
Development of a flexible CuO-ZnO Nano-Bulk junction with photovoltaic response using chemical bath deposition and spin coating techniques at temperatures lower than 330 K.
研究成果
The fabricated solar cell demonstrated photovoltaic response with an open circuit voltage of 0.25 V, short circuit current density of 2x10-6 A/cm2, fill factor of 8%, and efficiency of 0.11%. The device performance can be improved by optimizing parasitic resistance losses and interface formation.
研究不足
The interface formation between the blend and the p-type CuO is non-homogenous, and the device performance is limited by parasitic resistance losses.
1：Experimental Design and Method Selection:
The study involved the fabrication of a solar cell using chemical bath deposition for p-type CuO layer and spin coating for n-type ZnO layer and a blend of CuO-ZnO as a buffer layer.
2：Sample Selection and Data Sources:
Copper foil was used as the substrate for CuO deposition, and ZnO nanoparticles were synthesized using a sol-gel method.
3：List of Experimental Equipment and Materials:
XRD (Rigaku D.Max.C), UV-Vis-NIR spectrophotometer (Shimatzu UV 1800), spectro-fluorometer (JASCO FP8600), source measure unit (Aglient B2900).
4：0). Experimental Procedures and Operational Workflow:
4. Experimental Procedures and Operational Workflow: CuO was deposited on Cu substrate, followed by spin coating of CuO-ZnO blend and ZnO layer. Ag paste was applied for contacts.
5：Data Analysis Methods:
Electrical parameters were extracted from J-V characteristics using theoretical fitting.
