Compositions for forming wavelength-converting membranes easily by spin-coating, etc. are provided to improve photoelectric conversion efficiency by using wavelength-converting membranes formed without dispersing wavelength-converting substances or using rare earths. The compositions for forming the wavelength-converting membranes for photovoltaic devices comprise a polymer or an oligomer with introduced fluorescent regions and a solvent. The fluorescent regions are introduced into the main chain or side chain of the polymer or oligomer. The wavelength-converting membranes for photovoltaic devices are formed from said wavelength-converting membrane-forming compositions. La présente invention a trait à des compositions permettant de former avec facilité des membranes de conversion de longueur d'onde par dépôt à la tournette, etc., en vue d'améliorer le rendement de conversion photoélectrique en utilisant les membranes de conversion de longueur d'onde formées sans disperser des substances de conversion de longueur d'onde ou en utilisant des terres rares. Les compositions permettant de former des membranes de conversion de longueur d'onde pour des dispositifs photovoltaïques comprennent un polymère ou un oligomère dans lequel sont introduites des régions fluorescentes et d'un solvant. Les régions fluorescentes sont introduites dans la chaîne principale ou la chaîne latérale du polymère ou de l'oligomère. Les membranes de conversion de longueur d'onde pour des dispositifs photovoltaïques sont formées à partir desdites compositions permettant de former des membranes de conversion de longueur d'onde.
