Description

technical field [0001] The invention relates to a solar thermoelectric battery and a manufacturing method thereof, belonging to the technical field of battery manufacturing. Background technique [0002] Photovoltaic cells (also known as silicon photovoltaic cells or solar cells) and thermoelectric cells have been widely used. Photovoltaic cells mainly rely on the sun's irradiation to generate electricity, while thermoelectric cells mainly rely on the temperature difference effect generated on P-type and N-type semiconductors to generate electricity. At present, due to the influence of the irradiated area, sunshine time and temperature, the power generation efficiency of the existing photovoltaic cells is not very high; and the existing semiconductor thermoelectric cells are also affected by the use environment, which makes the temperature difference effect on the semiconductor Not too obvious, resulting in relatively low power generation efficiency. Therefore, the power ge...

[0002] Photovoltaic cells (also known as silicon photovoltaic cells or solar cells) and thermoelectric cells have been widely used. Photovoltaic cells mainly rely on the sun's irradiation to generate electricity, while thermoelectric cells mainly rely on the temperature difference effect generated on P-type and N-type semiconductors to generate electricity. At present, due to the influence of the irradiated area, sunshine time and temperature, the power generation efficiency of the existing photovoltaic cells is not very high; and the existing semiconductor thermoelectric cells are also affected by the use environment, so that the temperature difference effect generated on the semiconductor Less obvious, resulting in lower power generation efficiency

Therefore, the power generation efficiency of existing photovoltaic cells and thermoelectric cells is still not ideal.
