A new heterojunction (GP) p-FeIn₂Se₄-n-In₄Se₃ was formed by the mechanical contact of the FeIn₂Se₄ plate with the van der Waals surface of In₄Se₃. Investigation of Volt-Farada's, spectral characteristics and temperature dependences of the VAC of the heterojunction. On the basis of the analysis of electric and photovoltaic characteristics of the GP, a high-quality zone diagram was constructed. The region of spectral photosensitivity of p-FeIn₂Se₄-n-In₄Se₃ GP which is in the range 0.7-1.3 eV, is established.
