METHOD FOR DETERMINING THE PHOTOVOLTAIC PROPERTIES OF SOLID MATERIALS CAPABLE OF ACTING AS LIGHT ABSORBERS IN PHOTOVOLTAIC DEVICES

摘要

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.
