LiBr treated porous silicon used for efficient surface passivation of crystalline silicon solar cells

•The treatment of porous silicon with LiBr decreases the reflectivity to about 7%.•The effective lifetime of minority carrier augments from 1.4μs to 18.2μs.•The treated PS layers with LiBr, leads an enhancement of the PL intensity.•Improvement of the IQE on the spectral range from 400nm to 600nm.
