Hydrophilic HEMA-PUA is newly designed for stamping transfer of BHJ film without FOTS treatment.

Energy release rate of HEMA-PUA between PEDOT:PSS and BHJ are decreased due to modifying surface energy.

Stamping transferred BHJ exhibits the comparable device performance compared to spin-coating.

Physical phenomena of stamping transferred BHJ is proved by the analysis of FT-IR, UV–Vis, Nyquist plot, and AFM.

Stamping process based on transfer film will be expected to promising method in eco-friendly device fabrication.
