description •Selective etching based on screen-printing and diffusion was used to prepare silicon nano-textured surface.•Series resistance was significantly reduced due to the electrode-contact enhancement.•The efficiency of silicon nano-textured solar cells was improved by this technique. The electrode contact property of silicon nano-textured solar cell was investigated. An industrial feasible technique was introduced to enhance the electrode contact. The electrical performance of nano-textured cells with this contact enhancement was measured and compared with the ones without. The series resistance was reduced significantly from 1.5Ω to 0.3Ω and the short-circuit current was increased from 27mAcm−2 to 29mAcm−2. The cell efficiency was improved from 6% to 10%. These data indicate that the contact enhancement is effective.
