METHOD OF FORMING UNIFORM PEROVSKTIE LIGHT ABSORBING LAYER, AND SOLAR CELL COMPRISING UNIFORM PEROVSKTIE LIGHT ABSORBING LAYER

摘要

The present invention relates to a method for manufacturing a perovskite light absorbing object by using an MO sol-gel method. According to the present invention, a uniform perovskite light absorbing layer can be manufactured by forming MX_2 which is a precursor of the perovskite light absorbing object based on the MO sol-gel method. A perovskite solar cell made by the present invention provides an excellent solar cell feature by a uniform perovskite thin film.
