A Conventional scribing method is considered expensive and slow to make thin-film solar cells more efficient. A new method is carried out by researchers at Purdue University using ultrafast pulsed lasers to manufacture solar cells for cheaper and more efficient thin-film solar cells.
Ultrafast laser scribing is used to make small microchannels that will be used to interconnect a series of solar panels into an array to produce the amount of energy. It will also support in making a better channels. Thin films instead of wafers have been cut costs significantly.
According to the researchers, the accuracy of microchannels cuts will greatly affect the efficiency of a solar cell. They hope the manufacture microchannels using ultrashort pulse laser can reduce production costs and improve efficiency thin-film solar cells.
A cold ablation process has created a layer of microchannels are very clean and thin-film is not damaged by heat. The study also received financial support from the National Science Foundation.
