US-China crack code for toxic-free solar panels with 20% efficiency [Video]

A new design principle has been identified that could eliminate the use of toxic chemicals in solar cell manufacturing.  

The standard manufacturing process of organic cells involves toxic solvents. This environmental concern has hindered the widespread adoption of organic solar cells. 

Researchers at Linköping University (LiU) have revealed a new design principle for eco-friendly, high-efficiency organic solar cells.

To unlock this potential, they delved into the molecular shapes and interactions within organic solar cells. This led to the identification of a design principle that allows for the use of environmentally friendly solvents.

“To realise mass production of organic solar cells, with printed technologies for example, on a large scale, we need to find methods that don’t use toxins. Otherwise, it’s not good for the environment or for those working in the factories,” said Feng Gao, professor of optoelectronics …
