Greatly enhanced hole collection of MoO _x with top sub-10 nm thick silver films for gridless and flexible crystalline silicon heterojunction solar cells.

ABSTRACT: Greatly enhanced hole collection of MoO _x is demonstrated experimentally with a top sub-10 nm thick Ag film, allowing for an efficient dopant-free contacted crystalline silicon (c-Si) heterojunction solar cell without a front grid electrode. With the removal of shadows induced by the front grid electrode, the gridless solar cell with the MoO _x /Ag hole-selective contact (HSC) shows an increment of ∼8% in its power conversion efficiency (PCE) due to the greatly improved short-circuit current density (J _sc) as well as the almost undiminished fill factor (FF) and open-circuit voltage (V _oc), while the gridless solar cells with the conventional MoO _x /ITO and pure MoO _x HSCs exhibit ∼20%
