Data for: Improved CuGaSe2 absorber properties through a modified co-evaporation process

- The CuGaSe2 was synthesized using the sequential CuPRO process and the modified CuPROM process that implies 2 relaxation stages during the co-evaporation. - The Raman analysis was performed at the front and rear CuGaSe2 surface using 633 nm excitation wavelength. The .dat files contain the raw data of the Raman analysis - The .opj file contains the photovoltaic parameters (Voc, Jsc, FF and η) of the solar cells fabricated from CuGaSe2 absorbers. - The CuGaSe2-based thin-film solar cells consist of the following layers stack Mo/CGSe/CdS/ZnO/ZnO:Al deposited on 1 mm-thick soda-lime glass (SLG) substrate
