Title: PEROVSKITE SILICON TANDEM SOLAR CELL AND MANUFACTURING METHOD
Abstract:
The present invention relates to: a monolithic tandem solar cell in which a perovskite solar cell is stacked on and joined with a silicon solar cell; and a manufacturing method. According to the present invention, provided are: a tandem solar cell comprising, a substrate on which a texture having both a valley shape and a peak shape is formed, and a perovskite absorbing layer formed on the substrate, wherein the valley part and the peak part of the texture have a round shape; and a manufacturing method therefor, thereby uniformly improving efficiency of the tandem solar cell all over a panel and preventing shorting in a junction layer so as to prevent shorts.
