摘要：
A photovoltaic (PV) module in which electric power generation efficiency is enhanced by enhancing light utilization rate. A encapsulant (202) is a first layer, a wavelength conversion type light trapping film (300) is a second layer, an antireflection film (104) is a third layer and an n-type layer is a fourth layer. When the refractive indexed of the layers are expressed as first refractive index (n1), second refractive index (n2), third refractive index (n3) and fourth refractive index (n4), the following relation is satisfied; n1≦n2≦n3≦n4. The wavelength conversion type light trapping film (300) of the second layer has one structured surface on the light incident side and has a refractive index of 1.6-2.4. The wavelength conversion type light trapping film is transparent and contains a fluorescent substance.
