研究目的
To design a solar spectrum simulator using LED technology for the characterization of porphyrin-based dye-sensitized solar cells, addressing the limitations of halogen lamp-based simulators.
研究成果
The LED-based solar spectrum simulator effectively covers the main absorption peaks of porphyrin derivatives, avoiding the overheating issues associated with halogen lamps. The design offers a viable alternative for porphyrin DSSC testing and characterization, with potential improvements by incorporating additional blue LEDs.
研究不足
The proposed LED-based simulator may require additional blue-emitting power LEDs to fully exploit the absorption peak of porphyrin derivatives in the blue wavelength range. The complexity of the system and the need for a powerful cooling system are also considerations.
1：Experimental Design and Method Selection:
The design involves using power LEDs to reproduce the solar emission spectrum, focusing on the ultra-violet and visible ranges relevant to porphyrin dyes.
2：Sample Selection and Data Sources:
White LEDs of various color temperatures and a red-emitting LED were selected for spectrum measurements.
3：List of Experimental Equipment and Materials:
A FLAME miniature spectrometer, a bifurcated fiber optic probe, an adjustable power supply, and several 10 W LEDs were used.
4：Experimental Procedures and Operational Workflow:
LEDs were placed in a dark chamber, and their emission spectra were measured with the spectrometer set to specific integration times.
5：Data Analysis Methods:
The measured spectra were processed to obtain a total emission spectrum for the LED system.
