Abstract
The utility model discloses a high-light-transmittance thin film used for a solar cell. The high-light-transmittance thin film comprises an antireflection film layer, a blue light layer, a green light layer, a red light layer and a substrate layer. The high-light-transmittance thin film has a five-layer structure. The antireflection film layer is arranged at the uppermost layer and used for increasing light transmittance. The substrate layer is arranged at the bottommost layer and used as substrate base material for a photoelectric conversion layer. The red light layer, the green light layer and the blue light layer are respectively deposited on the substrate layer and are used for absorbing and converting light of corresponding colors respectively. The high-light-transmittance thin film is designed in five layers. With application of the antireflection film arranged at the uppermost layer, light transmittance can be effectively increased, reflection of sunlight on the surface of the thin film is greatly reduced and light utilization efficiency is enhanced; and three layers of amorphous silicon are deposited on the stainless steel substrate so that blue light, green light and red light in the sunlight can be sufficiently absorbed, energy can be effectively absorbed and conversion efficiency can be effectively enhanced.
