Organic photovoltaic cell micromolecule receptor material using naphtho-indenofluorene unit as core, and preparation method and application thereof

The invention discloses an organic photovoltaic cell micromolecule receptor material using a naphtho-indenofluorene unit as a core and a preparation method and the application thereof. The preparation method is characterized in that the polar substituent group containing naphtho-indenofluorene unit is used as the core; electron withdrawing units are sequentially connected to two sides of the naphtho-indenofluorene unit through coupling reaction to obtain the organic photovoltaic cell micromolecule receptor material using the naphtho-indenofluorene unit as the core; the organic photovoltaic cell micromolecule receptor material using the naphtho-indenofluorene unit as the core and a donor material are dissolved into an organic solvent; the surface of an ITO/ PEDOT: PSS is spirally coated with the mixture to form a film; then a residual organic solvent is removed by evaporating to dryness, therefore, an active layer of an organic photovoltaic cell can be obtained. The organic photovoltaic cell micromolecule rece
