研究目的
Investigating the implementation of Maximum Power Point Tracking (MPPT) for flexible organic polymer solar cells (FOPSC) under varying shading conditions for application in Unmanned Aerial Vehicles (UAVs).
研究成果
The FOPSC strips designed in this study, combined with a minimal sensor-based MPPT method, demonstrated the ability to harvest maximum power under varying shading conditions. This system's low cost, weight, and flexibility make it suitable for embedding into UAV airframes, potentially extending flight time by charging UAV batteries.
研究不足
The study focuses on single layer solar cells and does not explore the potential efficiency improvements with additional layers such as PEDOT:PSS. The MPPT technique's effectiveness under varying shading conditions is demonstrated, but further optimization may be required for more complex scenarios.
1：Experimental Design and Method Selection:
The study involved the fabrication of FOPSC using a composite of three conjugated polymers and CNT/rGO composite as counter electrode, with PET as substrate. The MPPT technique was developed using the second order derivative of output voltage with respect to duty cycle ratio (D2VOC).
2：Sample Selection and Data Sources:
The fabricated OPSC was tested under different shading conditions to obtain power to voltage relationships.
3：List of Experimental Equipment and Materials:
Materials included PFO, PEO-at-co-MEH-PPV, MEH-PPV, CNT/rGO composite, PET substrate. Equipment included a solar simulator for characterization.
4：Experimental Procedures and Operational Workflow:
The OPSC strips were connected in series, and shading conditions were recreated to test the MPPT method.
5：Data Analysis Methods:
The performance of the FOPSC was analyzed based on fill factor, open circuit voltage, and power conversion efficiency.
