Problems solved by technology

However, significant challenges remain to achieve this goal, especially achieving a fine balance between key parameters such as power conversion efficiency (PCE), through peak (T MAX ) and the half-maximum width (FWHM) of the transmission spectrum
The complex checks and balances and uncertain structure-property relationships among materials, devices, and interfaces remain major challenges

Abstract

The invention discloses an induced film forming method of thin-layer silver and a color semitransparent organic solar cell device employing the same. The thin-layer silver takes a Bis-FIMG material asa guide layer, and the silver is evaporated to the surface of the guide layer. Based on the design, the color semitransparent organic solar cell device structurally comprises a substrate, an anode, an anode modification layer, an organic active layer, a cathode modification layer and a Fabry-Perot resonant cavity, wherein the cathode modification layer is made of a fullerene ionic compound Bis-FIMG. The Bis-FIMG has a positive induction effect on thin-layer silver film formation, and the purposes of selective transmission of visible light wave bands and efficient absorption of other wave bands are achieved by means of regulation and control of the Fabry-Perot resonant cavity on the wave crest and half-peak width of a transmission spectrum. After the Fabry-Perot resonant cavity electrode is introduced, blue, green and red semitransparent organic solar cells with photoelectric conversion efficiency of 14.04%, 14.60% and 14.28% respectively and transmission peak values of 31.0%, 21.8% and 25.2% respectively can be flexibly prepared, which are one of the highest records of the comprehensive performance of the current color semitransparent organic solar cells.

Description

technical field [0001] The invention relates to a semi-transparent organic solar battery, in particular to a process for inducing the formation of a thin layer of silver in a Fabry-Perot resonant cavity in the battery. Background technique [0002] Building-integrated photovoltaics (BIPV) have attracted extensive attention from both academia and industry for their ability to harness solar power as a sustainable clean energy source while retaining properties such as light transmission and aesthetic decoration. Semitransparent organic solar cells (ST-OSCs) have tunable optoelectronic properties different from inorganic components and thus hold great promise in BIPV. [0003] Most of the translucent organic solar cells are mostly semi-transparent cells with a single color prepared by thin-layer silver electrodes. The photoelectric conversion efficiency is relatively low, depending on the photoactive layer material and the aesthetic decoration function is weak, so some effective...
