Abstract

The invention discloses a copper-indium-selenium nanowire array and a preparation method thereof. The method comprises the following steps: preparing a metal electrode layer on a glass or silicon slice substrate, using an ordered nano-template as growing mask to prepare the ordered nanowire structure copper-indium-selenium P-type absorbing layer material array on the metal electrode layer of the substrate through electrodeposition, and partly removing the template from top to bottom through chemical corrosion or physical etching method to expose the nanowire array. The array of the invention can be used to prepare the heterojunction solar cell with photoelectric translating performance.

Description

technical field

[0001] The invention belongs to the technical field of thin-film solar cells, and relates to a copper indium selenium nanowire array and a preparation method and application thereof. Background technique

[0002] As the energy issue has increasingly become a bottleneck restricting the development of the international community and China's economy, the development of solar energy technology has become one of the most important topics in the field of energy and materials research. It is imperative to develop low-cost, high-efficiency, and stable photovoltaic cells (M.A. Green, Progress in Photovoltaics: Research and Applications 9123-35 (2001)). Thin-film semiconductor photovoltaic cells are studied to reduce the manufacturing cost of battery components and promote the development of photovoltaic cell manufacturing industry (A.Barnett, A.Rothwarf, Thin-film solarcells: A unified analysis of their potential, IEEE Trans.Electron Devices 27 615 -630 (1980)). In ...
