Spray Coated Perovskite Solar Cells

Spray Coated Perovskite Solar Cells – Spray-on Solar Panels – Cheersonic

Scientists at Cheersonic Ultrasonic have developed a spraying method for producing solar cells, and ultrasonic precision spraying is a high-efficiency and low-cost method. Cheersonic Ultrasonic cooperates with universities to prepare solar cell thin films by spraying perovskite materials. The cost of perovskite materials is low, but the solar cells prepared by it can rival traditional silicon solar cells in terms of photovoltaic power generation. Therefore, perovskite is also a high-efficiency and low-cost material.

Ultrasonic atomization is a sophisticated coating technique that can be used to rapidly deposit functional thin films over large areas. Compared with other scalable technologies, ultrasonic spray deposition has two advantages. First, ultrasonic spray technology has high spraying efficiency. When used in conjunction with an assembly line, its spraying speed can reach up to 3.5m/min, which is usually 1.5 of the slit coating speed. times, significantly reducing the production cost of solar cells. Secondly, the preparation technology of ultrasonic spraying has unique advantages, which can not only coat uneven (3D) substrates, but also the uniformity and quality of the coating, and the thickness of the coating can be controlled.
