研究目的
Investigating the efficiency of solar cells at low temperatures in the Arctic to propose using solar modules for electricity generation from March to November.
研究成果
The study found that decreasing ambient temperature increases the open-circuit voltage of solar cells, with amorphous solar cells showing the best performance. Polycrystalline solar cells had slightly lower values. These results will guide the selection of solar modules for Arctic use in the 2020 season.
研究不足
The study did not cover the winter period from December to February due to the polar night when no electricity is generated. The maximum and minimum temperatures for 2018 were used for equipment selection, which may not represent all Arctic conditions.
1:Experimental Design and Method Selection:
The study focused on the operation of solar cells at low temperatures, using single-crystal, polycrystalline, and amorphous solar cells.
2:Sample Selection and Data Sources:
Solar cells were tested in a climatic chamber simulating Arctic temperatures.
3:List of Experimental Equipment and Materials:
A 10W LED floodlight with IP65 protection, Espec PG-2J climatic chamber, and B7-65 universal digital voltmeter were used.
4:Experimental Procedures and Operational Workflow:
Measurements were taken at temperature increments of 5°C from 18°C to -40°C, with continuous recording for 30 minutes at each temperature.
5:Data Analysis Methods:
The results were averaged and analyzed to determine the efficiency changes with temperature.
