This invention discloses an impact-resistant photovoltaic encapsulating film, its preparation method, and a photovoltaic module. The photovoltaic encapsulating film comprises multiple layers of unidirectional prepreg tape laminated together. The unidirectional prepreg tape is obtained by melt impregnation of thermoplastic resin and continuous fibers surface-treated with a coupling agent.
