The article studies the effect of low-temperature annealing of source single crystals InSe on the photoelectric properties of the heterojunctions n-InSe-p-InSe. It was found that the maximum improvement of the parameters of the heterojunctions was observed at annealing temperatures of the source material 150 - 200 °C and the duration of 4 hours. The improvement of the quality of single-crystal samples after annealing was confirmed by multiplicity of NQR spectra, which reflect the collating in the system of polytypes of layered structure of InSe. Reduction of defects, including stacking and flat dislocations defects during annealing had had positive effect on the photoelectric parameters of the heterojunctions. The latter follows the dynamics of the currentvoltage characteristics and the growth of photoresponse of the heterostructure n-InSe-p-InSe. The improvement of the characteristics of the heterojunction was connected with the change of concentration of defects near the heterojunction boundary and the decrease of the impedance in the volume of the sample along the c axis. For the annealed materials the structure n-InSe-p-InSe is characterized by an increase of the intensity of the exciton peak, the growth of the open-circuit potential from 0.29 to 0.56 V and the growth of the short-circuit current from 350 to 840 mkA/sm2. The maximum growth of the conversion factor according to the photocurrent and photovoltage at a wavelength of λ = 0,98 mkm after annealing was ΔSI = 89%, and ΔSV = 24%, respectively.References
