Embodiment Construction

[0027] 1. Synthesis of Aligned Carbon Nanotube Arrays

[0028] Growth of vertically spinnable multi-walled carbon nanotube arrays by chemical vapor deposition (CVD) with Fe catalyst

[0029] (1.2nm) / Al 2 o 3 (3nm) / SiO2 2 / Si,Al 2 o 3 and Fe are sequentially deposited on the silicon wafer using an electron beam evaporation coater, in which Al 2 o 3 As a buffer layer, Fe as a catalyst, ethylene as a carbon source, hydrogen and argon as carrier gases, were grown in a tube furnace at 740 °C for 10 min.

[0030] 2. Prepare the counter electrode, and pull out the aligned multi-walled carbon nanotube film on the spinnable multi-walled carbon nanotube array.

[0031] 3. Prepare the working electrode. First, use the two-electrode method to anodize the cleaned titanium wire for 10 minutes, anodize the titanium dioxide tube on the surface of the titanium wire, and then calcinate it in a tube furnace at 500 degrees Celsius for 1 hour and anneal it. After cooling down to room tempera...

Abstract

The invention belongs to the technical field of integrated devices, and particularly relates to an all-solid-state fibrous coaxial polymer solar cell and super capacitor integrated device and a preparation method thereof. The integrated device provided by the invention is formed by taking a titanium dioxide coaxially wound by a multi-wall orientation carbon nano tube thin film as an electrode, wherein one end of the integrated device is a polymer solar cell, and the other end is a super capacitor. The multi-wall orientation carbon nano tube thin film has good light transmission and conductivity, is a good electrode material and low in cost, and has good development prospects.

Description

technical field [0001] The invention belongs to the technical field of integrated devices, in particular to an integrated device of a polymer solar cell and a supercapacitor. Background technique [0002] Since the first discovery of carbon nanotubes (CarbonNanotubes, CNTs) by Iijima in Japan in 1991, carbon nanotubes have been widely valued by people for their unique mechanical, electrical, thermal and other properties. They have good development prospects and will surely become a new generation of popular materials. . [0003] Carbon nanotubes can be divided into single-wall carbon nanotubes and multi-wall carbon nanotubes according to the number of graphite sheets. The unique carbon nanotube structure endows it with excellent mechanical and electrical properties, such as Young's modulus up to 1000 GPa (about 5 times that of steel), and tensile strength up to 63 GPa (about 50 times that of steel). Due to the lower density of carbon nanotubes (about 1 / 6 of steel), higher ...
