Abstract
The invention belongs to the technical field of solar cells, and particularly relates to a perovskite cell manufacturing method and the perovskite cell. The manufacturing method comprises the following steps of manufacturing a first contact layer on a transparent conductive layer, manufacturing the first contact layer into an inverted pyramid-shaped light trapping structure by using laser processing equipment, and sequentially depositing a perovskite layer, a second contact layer and a conductive electrode on the light trapping structure. The laser processing equipment comprises a laser emitter, a light gathering mechanism and a sealed container, a light scattering mechanism is arranged in the sealed container, and in the step of manufacturing the first contact layer into the inverted pyramid-shaped light trapping structure by using the laser processing equipment, the laser emitter is controlled to emit laser towards the first contact layer arranged in the sealed container through the light gathering mechanism; the light scattering mechanism scatters the laser and reduces the laser energy, and finally the textured surface with the height in the range of 5-50 nm is prepared on the first contact layer, so that the height of the textured surface is reduced, the light reflection is reduced, and the photon utilization rate is effectively increased.
Description
technical field [0001] The invention belongs to the technical field of solar cells, and in particular relates to a manufacturing method of a perovskite battery and a perovskite battery. Background technique [0002] With the continuous development of the photovoltaic industry, the dominant silicon cell has also faced new challenges in its 66-year history. At present, the efficiency of crystalline silicon cells is close to the theoretical efficiency limit of 29.4%, and the mass-produced PERC cells have also broken through the efficiency limit of 23%. How to improve the efficiency limit of silicon cells has become a research hotspot in today's academic circles. [0003] As the third-generation solar cell, perovskite has been invented in 2009, and its photoelectric conversion efficiency has exceeded 25% in just 11 years. Due to its high photoelectric conversion efficiency, perovskite has become one of the main development directions of silicon cells in the future. . However, ...
