Improved PEDOT:PSS/c-Si hybrid solar cell using inverted structure and effective passivation.

ABSTRACT: The PEDOT:PSS is often used as the window layer in the normal structured PEDOT:PSS/c-Si hybrid solar cell (HSC), leading to significantly reduced response, especially in red and near-infrared region. By depositing the PEDOT:PSS on the rear side of the c-Si wafer, we developed an inverted structured HSC with much higher solar cell response in the red and near-infrared spectrum. Passivating the other side with hydrogenated amorphous silicon (a-Si:H) before electrode deposition, the minority carrier lifetime has been significantly increased and the power conversion efficiency (PCE) of the inverted HSC is improved to as high as 16.1% with an open-circuit voltage (V_oc) of 634 mV, fill factor (FF) of 70.5%, and short-circuit current density (J_sc) of 36.2 mA cm^-2,
