A method for inhibiting light-induced degradation of a photovoltaic device (2) includes steps of: a) subjecting the photovoltaic device (2) to an illumination treatment using a light having a wavelength not less than 300 nm to heat the photovoltaic device (2) in the absence of ambient light; and b) maintaining the temperature of the photovoltaic device (2) above an annealing temperature of the photovoltaic device (2) for at least 0.5 minute. An apparatus (1) for inhibiting light-induced degradation of a photovoltaic device (2) is also disclosed.
