  • DISPERSION LIQUID FOR FORMATION OF SEMICONDUCTOR ELECTRODE LAYER, AND SEMICONDUCTOR ELECTRODE LAYER
    Publication number: 20230386760
    Abstract: The present invention relates to a slurry for forming a semiconductor electrode layer to obtain a dye-sensitized solar cell containing a porous layer, which is not susceptible to cracking and is capable of providing a higher conversion efficiency. The slurry for forming a semiconductor electrode layer contains two types of metal-oxide semiconductor particles having different particle sizes. When a semiconductor electrode layer is formed by coating and sintering such a slurry, cracking seldom occurs and a higher conversion efficiency is achieved when it is made into a film with a thickness of 3˜20 ?m.
    Type: Application
