Abstract This work explores a strategy to bring together the advantages of co‐evaporation and sputtering by developing hybrid co‐sputtering/evaporation process, where copper, indium, gallium are sputtered with thermal evaporation selenium. A 3‐stage process for Cu(In,Ga)Se 2 (CIGS) thin films solar cells has been developed controlling deposition parameters (temperature, power, evaporation). (In,Ga) Se 3 layers deposited in first stage, followed Cu − x Se/(In,Ga) layers. Material properties at different steps were studied detail X‐ray fluorescence, energy dispersive X‐ray, scanning electron microscopy, glow discharge optical emission spectroscopy, Raman diffraction. Solar completed leading 9.7% efficiency.
