Figure 4

(a) J–V curves of the champion CNT/n-Si heterojunction solar cells without and with passivation. The inset of (a) is the digital image of the solar cell with passivation. (b) Log J–V curves of the champion CNT/n-Si heterojunction solar cells in the dark. (c) The EQE spectra of the champion CNT/n-Si heterojunction solar cells without and with passivation under AM 1.5 G irradiation.
