Abstract

The invention provides a semitransparent polymer solar cell having a gaschromic function and a preparation method thereof and belong to the technical field of organic optoelectronic devices. From bottom to top, the solar cell consists of an ITO conductive glass cathode, a PFN cathode buffer layer, a PTB7-Th:FOIC active layer, a MoO3 anode buffer layer, a Ag anode and a WO3/Pt gaschromic structurallayer. An active layer acceptor material FOIC has the very strong light absorption from a visible light area to a near-infrared area (600-950nm) and has the high electron mobility of 1.2*10-3cm2V-1s-1, extinction coefficient can be as high as 2*105 m-1 cm-1, and a low band gap is 1.32 eV. A WO3 film has strong absorption in the infrared and visible wave bands of a solar spectrum in a colored state and is combined with a semitransparent polymer solar cell device, the capability of absorbing light in the visible and infrared area of the device is remarkably enhanced under the hydrogen introduction condition, and accordingly the purpose of improving photoelectric conversion efficiency is achieved.

Description

technical field [0001] The invention belongs to the technical field of organic photoelectric devices, in particular to a 3 A translucent polymer solar cell with an aerochromic function and a Pt nanoparticle structure and a preparation method thereof. Background technique [0002] Polymer solar cells (PSCs) have been widely studied and become one of the most promising photovoltaic technologies due to their outstanding advantages of light weight, solution processability and large-scale production. In recent years, semitransparent polymer solar cells (ST-PSCs) have attracted increasing attention in the fields of science and industry because they can be used as power generation windows for large-area applications in buildings, cars or self-powered greenhouses. However, the function of semi-transparent polymer solar cells is still relatively simple, generally only has the two functions of photoelectric conversion and sunlight transmission, which cannot meet the growing applicati...
