How efficient is a silicon solar cell?
Using this approach, we produced a silicon solar cell that exceeded 27% efficiency. Hydrogenated amorphous silicon layers were deposited onto the wafer for surface passivation and to collect light-generated carriers. A dense passivating contact, which differs from conventional technology practice, was developed.
How do silicon solar cells work?
Silicon solar cells usually have a single electrode on each side so that they are front- and back-contact cells. The electrode grid on the sunny side obstructs light, thus reducing energy input. Placing both terminals on the shaded side creates back-contact solar cells that are potentially more efficient and also aesthetically appealing.
