Abstract: Disclosed are a semi-transparent solar cell device and an application. The cell device comprises a cathode, a hole transport layer, a photoactivity layer, an electron transport layer and an anode, wherein the photoactivity layer absorbs near-infrared and infrared light with a wavelength range greater than 780 nm. The cell device fully utilizes light energy in different bands, thus increasing the light energy utilization rate. By combining a semi-transparent solar cell and a heat-insulating film, not only can the cell device be used for generating power as a photovoltaic cell, but the device can also be attached to glass of a car or of an exterior wall of a building to be used as the heat-insulating film because of having excellent heat insulation performance itself. The cell device solves the problems of high visible light transmittance, high photoelectric conversion efficiency, heat insulation, ultraviolet protection, etc.
