Embodiment Construction

[0019] First, the synthesis of aligned carbon nanotube arrays.

[0020] Vertically grown carbon nanotube arrays with Fe(1nm) / Al 2 o 3 (10nm) / SiO 2 / Si as a catalyst was synthesized using typical chemical vapor deposition in a quartz tube of a tube furnace. Al in the catalyst 2 o 3 It is located in the middle of the silicon wafer and Fe, as a buffer layer, and Fe as a catalyst, which are prepared by depositing a nanometer-thick film on the silicon wafer by an electron beam evaporation coating device. Using chemical vapor deposition method, ethylene is used as carbon source, argon and hydrogen are used as carrier gas, and highly oriented carbon nanotube arrays are synthesized on Si substrate with oxide layer. The details of the synthesis can refer to the existing literature reports.

[0021] Second, the preparation of aligned carbon nanotube film electrodes

[0022] Stick the tape on the substrate with a thickness of 100 nm-2 mm, and make it vertically contact with the to...

Abstract

The invention belongs to the technical field of a solar battery, in particular relates to a preparation method of a high-performance orientation carbon nano tube film electrode. The method comprises steps of preparing an orientation carbon nano tube thin-layer array by utilizing an adhesive tape method, and preparing the high-performance orientation carbon nano tube film electrode by utilizing a pressurizing method. The method is simple to operate, the controllability is good, and the surface of the prepared carbon nano tube film electrode is smooth and homogenous. The orientation carbon nano tube film electrode is used as a counter electrode of a solar battery, the assembled solar battery has excellent performance, and the efficiency of the assembled solar battery can exceed the efficiency of the battery adopting traditional platinum as the counter electrode under the same condition.

Description

technical field [0001] The invention belongs to the technical field of solar cells, and in particular relates to a preparation method of an aligned carbon nanotube film used for a counter electrode of a solar cell. Background technique [0002] As we all know, the earth is currently facing a very severe energy crisis. Solar cells, as one of the most promising avenues to solve the energy crisis, have received extensive attention from academia and industry in recent years 1-3 . At present, inorganic solar cells are more researched, but the shortcomings of limited resources, complicated preparation process and high cost have become the key to restrict their application. 4-6 . Therefore, the research on organic solar cells has aroused strong interest of domestic and foreign scholars in recent years. However, the performance of organic photovoltaic materials still needs to be improved. Counter electrode material, as one of the important components of organic solar cells, is ...
