got an inkjet printer? print solar cells
By inkjet technology I mean similar to inkjet printers, solar photovoltaic material can be deposited onto a substrate with minimal material usage and waste through use of a digitally controlled process. I’ve read some articles in the past about a university student that basically modified a standard inkjet printer to print very low efficiency solar cells that actually produced a small electrical charge!
Obviously we are far away from being able to print solar cells in our own homes, but the concept can be revolutionary especially in the developing word. We could one day take an inkjet printer into an Afican village and print solar cells right at the point of use and change the lives of the billions of people who have no access to clean energy.
