Why thick-film organic solar cells are more conducive to large-area printing?

Thick film organic solar cells are more conducive to large-area printing because of their high efficiency. Organic solar cells utilize the photovoltaic effect of organic semiconductor materials with yokes to realize the photoelectric conversion of solar energy, and can be printed on flexible substrates at low temperature, which has the potential advantages of light weight, thin thickness, flexibility and low cost. The energy conversion efficiency of single-junction organic solar cells has reached more than 14%, and its research has been widely concerned by scientists. In solar cells, the film thickness of the interface material of anode or cathode is often 3- 10nm to achieve high efficiency.
