Title: METHOD FOR MANUFACTURING PEROVSKITE SILICON TANDEM SOLAR CELL
Abstract:
The present invention relates to a method for manufacturing a monolithic tandem solar cell in which a perovskite solar cell is laminated and bonded on a silicon solar cell. According to the present invention, a first microporous precursor thin film is formed through a sputtering method on a substrate having an unevenly structured texture and then a halide thin film is formed on the first microporous precursor thin film to form a perovskite absorption layer, whereby light reflectance can be reduced and a path of light can be increased, and accordingly a light absorption rate can be increased.
