Amorphous Silicon Solar Cell
The overall efficiency of this new type of solar cell was 7.1–7.9% (under simulated solar light), which is comparable to that of amorphous silicon solar cells [1]. The main difference between this type of solar cell and conventional cells is that in the new cells the functional element, which is responsible for light absorption (the dye), is separated from the charge carrier transport.
