High efficiency planar Si/organic heterojunction hybrid solar cells

High efficiency planar Si/organic heterojunction hybrid solar cells

We present an efficient hybrid solar cell based on poly (3,4-ethylene-dioxythiophene):polystyrenesulfonate and planar Si with (100) and (111) orientations. The effect of Si surface native oxide on cell performance is studied. Compared to cell with hydrogen-terminated Si surface, the cell with oxygen...
