Researchers at Purdue University’s Center are developing a technology that employs ultrafast pulsing laser to help make solar cells more affordable and efficient.

The technology will help experts overcome two main issues: the need to reduce manufacturing costs and increase the efficiency of converting sunlight into an electric current, said Yung Shin.

The cells use tiny “microchannels” needed to interconnect a series of solar panels into an array capable of generating useable amounts of power, he said.

Conventional “scribing” methods, which create the channels mechanically with a stylus, are slow and expensive and produce imperfect channels, impeding solar cells’ performance.

“Production costs of solar cells have been greatly reduced by making them out of thin films instead of wafers, but it is difficult to create high-quality microchannels in these thin films,” Shin said.
