▎ 摘　　要

NOVELTY - Semi-transparent all-polymer solar cell device based on light management engineering comprises a substrate, transparent anode, hole transport layer, activelayer, cathode interface layer and transparent cathode. The active layer is the main body heterojunction structure of electron donor material and electron acceptor material, where the electron donor materialis selected from carbazole, polythiophene, or poly-indole carbazole. The electron acceptor material is selected from organicsemiconductor polymer. USE - Semi-transparent all-polymer solar cell device based on light management engineering. ADVANTAGE - The high-stability semi-transparent full-polymer solar battery device has excellent performance and good stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a translucent all-polymer solar cell device based on light management engineering, which involves: (A) cleaning the transparent conductive glass and placing in an oven to dry; (B) spin-coating a hole transport layer on the transparent conductive glass layer at a speed of 2000-5000 revolutions per second and a thickness of 20-80 nanometers, followed by thermal annealing at 100-200 degrees C for 10-30 minutes; (C) dissolving donor material and the acceptor material in chlorobenzene or chloroform solution, spin-coating the mixed solution on the hole transport layer to obtain an active layer with a thickness of 20-1000 nanometers; (D) spinning the alcohol-soluble cathode interface material coated on the active layer, the thickness of which is between 5-1000 nanometers; and (E) vapor-depositing silver electrode of 20-100 nanometers on the cathode interface layer.
