NOVELTY - A wavelength conversion film, comprises: an optically transparent polymer matrix; a first organic photostable chromophore having an absorption maximum less than 400 nm and an emission maximum greater than 400 nm.    USE - In photovoltaic module, luminescent panel, luminescent light and energy collection panel and greenhouse panel, use for increasing growth rate of plant and increasing the fruit yield of plant (claimed), and for greenhouse roofs.    ADVANTAGE - The wavelength conversion films exhibits improved photostability; improves the solar harvesting efficiency of solar cells, solar panels, or photovoltaic devices; improves solar light wavelength profile for improved plant nutrition and/or growth; and m provides luminescent light and energy collection panel that increases the growth rate and fruit yield of plant by 5-30%, relative to a plant not exposed to light that has been filtered.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) a photovoltaic module comprising: at least one photovoltaic device; and the wavelength conversion film, where the wavelength conversion film is configured to encapsulate the photovoltaic device such that incident light passes through the wavelength conversion film prior to reaching the photovoltaic device;    (2) a method for improving the performance and the lifetime of a photovoltaic device involves: either applying the wavelength conversion film to the photovoltaic device, where the wavelength conversion film is configured to encapsulate the photovoltaic device such that incident light passes through the wavelength conversion film prior to reaching the photovoltaic device; or incorporating a wavelength conversion film directly into the photovoltaic device during its fabrication, such that the wavelength conversion film is encapsulated between the photovoltaic device and a cover substrate on the light incident side;    (3) a luminescent panel comprising at least one wavelength conversion film;    (4) a luminescent light and energy collection panel comprising at least one solar energy conversion device and the luminescent panel, where the solar energy conversion device receives a portion of photons and converts those photons into electricity;    (5) a method for increasing the growth rate of a plant involving: exposing a plant to light that has been filtered through the luminescent panel; or exposing a plant to light that has been filtered through the luminescent light and energy collection panel;    (6) a method for increasing the fruit yield of a plant involving: exposing a plant to light that has been filtered through the luminescent light and energy collection panel; and    (7) a greenhouse panel comprising: at least one wavelength conversion layer comprising: a light absorbing surface where the light absorbing surface is configured to absorb incident photons; a first organic photostable chromophore having an absorption maximum of 300-450 nm and an emission maximum of 400-520 nm; and a second organic photostable chromophore having an absorption maximum of 480-620 nm and an emission maximum of 550-800 nm.
