研究目的
Investigating the effect of layer thickness on the power conversion efficiency (PCE) of P3HT:PCBM based organic solar cells to achieve optimum efficiency at low cost.
研究成果
The study concludes that optimizing the thickness of the P3HT:PCBM active layer and the PEDOT:PSS polymer layer can significantly improve the PCE of organic solar cells. The highest efficiency of 4.50% was achieved with a P3HT:PCBM thickness of 2.2×10-7 m and a PEDOT:PSS thickness of 1×10-7 m. The results suggest that adjusting the polymer layer thickness while keeping the active layer at an optimum value can yield better PCE outputs.
研究不足
The study is based on simulation results using GPVDM software, which may not fully capture all real-world variables affecting organic solar cell performance. The analysis is limited to the specific materials and configurations used in the simulation.
1：Experimental Design and Method Selection:
The study used the GPVDM software to simulate the effect of changing the thickness of the P3HT:PCBM active layer and the PEDOT:PSS polymer layer on the PCE of organic solar cells.
2：Sample Selection and Data Sources:
The simulation model was based on a planner heterojunction architecture of P3HT:PCBM based solar cell with layers configured as ITO/PEDOT:PSS/P3HT:PCBM/Al.
3：List of Experimental Equipment and Materials:
GPVDM software was used for simulation.
4：Experimental Procedures and Operational Workflow:
The thickness of the PEDOT:PSS layer was fixed at six different values while varying the P3HT:PCBM layer thickness (case-I), and vice versa (case-II). The PCE was then calculated for each configuration.
5：Data Analysis Methods:
The PCE curves were plotted for both cases to analyze the effect of layer thickness on efficiency.
