Problems solved by technology

But this method of adjusting the color of ST-PSCs is not dynamically reversible, and cannot make the color and AVT of the device change intelligently.
This largely limits the widespread commercial application of semitransparent polymer solar cells

Abstract

The invention belongs to the field of battery materials, and particularly relates to a semitransparent polymer solar battery and a production method thereof. The semitransparent polymer solar batteryprovided by the invention comprises a transparent substrate covered with an ITO film, an electron transport layer, an active layer, a hole transport layer, a metal electrode layer and a gasochromic layer which are arranged in sequence, wherein the gasochromic layer includes an Nb2O5 film layer and Au nanoparticles distributed on the surface of the Nb2O5 film layer. According to the solar battery provided by the invention, the Nb2O5 film with Au nanoparticles distributed on the surface is used as the gasochromic layer so that the color and the visible light average transmittance of the semitransparent polymer solar battery can be dynamically and reversibly adjusted; and the solar battery can be reversibly switched between a colored state and a bleached state, photon capture can be enhancedin a wider wavelength range, the short-circuit current density and the photoelectric conversion efficiency are high, and a market prospect is very wide.

Description

technical field [0001] The invention belongs to the field of battery materials, in particular to a semitransparent polymer solar battery and a preparation method thereof. Background technique [0002] In the past decade, polymer solar cells have attracted extensive attention from scientists due to their advantages of solution processability, light cell mass, low cost, and large-scale production. Among them, the semi-transparent polymer solar cells (ST-PSCs) made by sandwiching the active layer between two transparent electrodes have the functions of shading light, cooling energy, saving energy and protecting privacy while performing photoelectric energy conversion. Considered to be one of the best options for photovoltaic glazing required in Building Integrated Photovoltaics (BIPVs). At the same time, thanks to the fact that semi-transparent polymer solar cells can be prepared as flexible devices and their bright and tunable colors make them very promising in the applicatio...
