Abstract

The o-iminobenzoquinone complexes of lanthanum, samarium, and ytterbium, Ln(L)3 (L = 3,5-ditert- butyl-1,2-quinone-1-(2-oxy-3,5-di-tert-butylphenyl)imine) are synthesized. In order to study the photovoltaic properties of the obtained complexes and previously synthesized similar complexes of zinc and aluminum M(L)2 prototypes of photovoltaic cells are prepared on their basis. An examination of the fabricated devices has revealed that nanolayers of all the compounds, except for ytterbium complex, exhibited photovoltaic properties. The best results of energy conversion are achieved for single-layer cells containing zinc complex as a photoactive material (Open-circuit voltage U OC = 1.01 V, short-circuit current J SC = 5.2 nA/cm2).
