Depositing Thin Film Solar Cell Coatings

Depositing Thin Film Solar Cell Coatings – Solar Cell Roll-to-roll Coating System – Cheersonic

A solar cell and a power generation system are a technology for directly converting solar energy into electrical energy and receive sunlight and then immediately generate electricity by using the solar cell made up of a semiconductor, dye, polymer, etc. Compared with this, a solar power generation is provided which absorbs the radiant energy of the sun and converts into thermal energy.

The thin film solar cell requires much less amount of a raw material used than that of a crystalline silicon solar cell, has a larger area and can be mass-produced. Therefore, the manufacturing cost of the thin film solar cell can be reduced. Also, the thin film solar cell has a light absorption layer of which the thickness is several μm, and thus, consumes a very small amount of the raw material.

Cheersonic has recently developed an ultrasonic roll-to-roll coating method to fabricate organic solar cell film layers, which utilizes a roll-to-roll process to fabricate the electron transfer layer and active layer of organic solar cells. The method adopts the ultrasonic coating technology in the middle, which can manufacture the film layer of the solar cell in a large area, reduce the cost, and the formed film layer has good efficiency.
