NOVELTY - A sealing film comprises front surface-side sealing film (13A) formed between solar cell element (14) and front surface-side protective component (11) and containing resin material and wavelength-conversion material which converts light in ultraviolet region into light having wavelength in visible region or in near infrared region, and back surface-side sealing film (13B) formed between solar cell element and back surface-side protective component (12) and containing resin material and inorganic ultraviolet-shielding agent.    USE - Sealing film is used for sealing solar cell element between front surface-side protective component and back surface-side protective component in solar cell (claimed).    ADVANTAGE - The sealing film improves the power generation efficiency of solar cell element by containing a wavelength conversion material, and maintains power generation efficiency-improving effect even when solar cell is used for long period of time.    DETAILED DESCRIPTION - A sealing film comprises a front surface-side sealing film formed between a solar cell element and a front surface-side protective component and containing a resin material and a wavelength-conversion material which converts light in the ultraviolet region into light having wavelength in the visible region or in near infrared region, and a back surface-side sealing film formed between the solar cell element and the back surface-side protective component and containing a resin material and an inorganic ultraviolet-shielding agent. The front surface-side sealing film and the back surface-side sealing film do not substantially contain an organic ultraviolet absorbent. An INDEPENDENT CLAIM is included for solar cell, which is formed by interposing a pair of sealing films between front surface-side protective component and the back surface-side protective component, and sealing solar cell element.
