FIELD: physics.
SUBSTANCE: invention relates to organic electronics and specifically to organic photovoltaic devices (solar panels and photodetectors) using organic fluorine-containing compounds as modifying additives. The invention relates to an organic photovoltaic device with a bulk heterojunction, comprising series-arranged substrate, hole-collecting electrode, hole-transporting layer, photoactive layer consisting of a mixture of an n-type semiconductor material, a p-type semiconductor material and an organic fluorine-containing compound, an electron-transporting layer, an electron-collecting electrode and a substrate. The photoactive layer further contains a fluorine-containing modifier 
F1-F8 in concentration of 0.000000001-40 wt %. The invention also relates to a method of making a photovoltaic device, where a fluorine-containing modifier is added to a solution of semiconductor components, from which photoactive films are formed. The invention also relates to use of fluorine-containing modifiers F1-F8 to enhance performance of organic solar panels with a bulk heterojunction.
EFFECT: developing novel nano-structure modifying additives for polymer-fullerene systems capable of enhancing performance of photovoltaic devices.
