摘要： A wavelength conversion member (20) includes a fluoride phosphor (25) activated by Ce3+ or Eu2+. Then, with regard to the fluoride phosphor, internal quantum efficiency measured at 80° C. is 85% or more when internal quantum efficiency measured at 30° C. is taken as 100%. Moreover, a photovoltaic device includes the above-mentioned wavelength conversion member. The wavelength conversion member uses a fluoride phosphor, in which a decrease of the internal quantum efficiency is suppressed, and excellent temperature characteristics are imparted. Therefore, the wavelength conversion member can effectively utilize ultraviolet light even at high temperature, and it becomes possible to enhance an output of the photovoltaic device.
