研究目的
Investigating the applications of organic photovoltaic (OPV) cells in indoor light environments to achieve higher power conversion efficiency (PCE) and stability.
研究成果
The study demonstrates that OPV cells have good indoor applications, with the PBDB-TF:ITCC-based device achieving a top PCE of 22% under 1000 lux LED illumination. The results suggest that designing wide-bandgap active materials with low Vloss is key to achieving excellent photovoltaic performance in indoor environments.
研究不足
The study highlights the challenges of large-scale solar farms using OPV modules, such as device stability under strong illumination and heat. The photoresponse of the PBDB-TF:ITCC-based OPV cell still does not match particularly well with the large Eloss, indicating room for improvement.
1：Experimental Design and Method Selection:
The study focused on optimizing the active layers of OPV cells to match indoor light sources, specifically LED illumination.
2：Sample Selection and Data Sources:
1 cm2 OPV cells were fabricated using a polymer donor PBDB-TF and a nonfullerene acceptor ITCC.
3：List of Experimental Equipment and Materials:
A high-precision fiber optics spectrometer (Maya2000 Pro, Ocean Optics) was used to evaluate light intensities.
4：Experimental Procedures and Operational Workflow:
The photovoltaic performance was measured under varied light intensities, and the stability of the devices was tested under continuous illumination.
5：Data Analysis Methods:
The integral current densities were calculated using the EQE and photon flux spectrum to confirm the reliability of photovoltaic measurements.
