[ES] La presente invención está dirigida a un método para determinar mediante una reacción fotocatalitica las propiedades fotovoltaicas de materiales sólidos susceptibles de actuar como absorbentes de luz en dispositivos fotovoltaicos, que comprende al menos las siguientes etapas: poner en contacto el material con un fluido que contiene al menos una especia química susceptible de reaccionar por transferencia electrónica con dicho material; irradiar el material mientras está en contacto con el fluido al menos una vez con un haz de luz que se compone de al menos una longitud de onda dentro del espectro solar; y determinar mediante análisis químico y/o espectroscópico del fluido la variación de la concentración de la o las especies químicas susceptibles de reaccionar po transferencia electrónica, y/o la presencia y concentración de al menos un producto resultante de la reacción de transferencia electrónica entre el material sólido y la o las especies químicas citadas.
[EN] The present invention relates to a method for determining, by means of a photocatalytic reaction, the photovoltaic properties of solid materials capable of acting as light absorbers in photovoltaic devices, which includes at least the following steps: placing the material in contact with a fluid that contains at least one chemical species capable of reacting by electron transfer with said material; irradiating the material while the latter is in contact with the fluid at least once with a beam of light made up of at least one wavelength within the solar spectrum; ; and determining by chemical and/or stereoscopic analysis of the fluid the variation in the concentration of the chemical species capable of reacting by electron transfer and/or the presence and concentration of at least one product resulting from the electron transfer reaction between the solid material and the aforementioned chemical species.
