Abstract

The invention provides a thin film solar cell. The thin film solar cell comprises a light transmitting substrate, a transition layer, a transparent conductive oxide layer upper electrode, a photoelectric conversion layer, an infrared control layer and a transparent conductive oxide layer lower electrode. The light transmitting substrate is the incident surface of the thin film solar cell. The infrared control layer has the remarkable effect of absorbing the red light and the near-infrared light and can significantly reduce the infrared light transmittance of the thin film solar cell. The invention also provides heat insulating solar laminated glass including the thin film solar cell. The infrared control layer is combined with a bottom adhesive film having the infrared insulating effect ora transparent backboard so that the infrared transmittance and the total solar energy transmittance of the heat insulating solar laminated glass can be significantly reduced. The invention also discloses a manufacturing method of the thin film solar cell and the heat insulating solar laminated glass.

Description

technical field [0001] The invention relates to a thin-film solar cell and a manufacturing method thereof, and also relates to a heat-insulating solar laminated glass. Background technique [0002] In the solar spectrum, infrared light with a wavelength range of 780-2500nm accounts for 53% of the total radiant energy and is the main source of heat, followed by visible light with a wavelength range of 380-780nm and accounts for 44% of the total radiant energy. In order to reduce the thermal effect inside the building or vehicle, it is necessary to block infrared light to reduce the energy consumption of the building or vehicle to adjust the temperature, so as to achieve the effect of energy saving and environmental protection; on the other hand, in order to realize the function of decoration, it is also necessary Adjust the visible light to meet the requirements of light transmission and color in different application scenarios. [0003] Usually, green glass is used on the o...
