A light-converting conductive glass, its preparation method, and a perovskite solar cell

Abstract

This invention discloses a light-converting conductive glass, its preparation method, and a perovskite solar cell. The light-converting conductive glass is obtained by PECVD sputtering an ITO conductive layer onto a luminescent glass substrate with the chemical formula (100-x-4y)SrO-200B2O3-xCeO2-yTb4O7 (15≤x≤22, 1≤y≤5). The glass substrate of this invention can absorb ultraviolet light and convert it into visible light. Replacing conventional conductive glass as the glass substrate for perovskite solar cells, it can convert ultraviolet light, which is insensitive to or harmful to solar cells, into visible light. This slows down the efficiency degradation of perovskite solar cells with prolonged illumination, significantly enhancing their stability. Furthermore, compared to perovskite solar cells with conventional ITO glass substrates, its photoelectric conversion efficiency is also greatly improved.
