(a) The PEDOT:PSS film spin-coated on the quartz glass substrate. (b) A schematic of the PEDOT:PSS/n-Si heterojunction solar cell with the passivated oxide layer. The J–V curves of the PEDOT:PSS/n-Si heterojunction solar cells with n-Si substrates passivated (c) at 500 °C for 0–10 min and (d) at 400–800 °C for 1 min.
