Problems solved by technology

Relevant documents also apply photonic crystals to the structure of dye-sensitized solar cells (J.Am.Chem.Soc. Phys.Chem.B2005, 109, 15968~15976.Appl.Phys.Lett.2006, 88, 193110.), confirmed the enhancement effect of photonic crystals on solar cells from both experimental and theoretical aspects, but the enhancement effect is not yet significant; Moreover, the introduction of a photonic crystal layer into the structure complicates the process of preparing the battery

Abstract

The invention relates to an application of colloid photon crystal films, in particular relates to the application field of sunlight selective utilizations, and concretely relates to a process for preparing whole visible light condensers with surface photon crystal film frames. The invention is a surface photon crystal film of reflecting whole visible light, which is deposited on a surface of a concave substrate, diffusing reflecting properties of photon crystals in a large range of the whole visible light are used, visible light density on dye-sensitized solar cells through obtained surface mirrors are increased, when the whole visible light condensers which are obtained by the invention are applied for solar cells, and thereby photoelectric conversion efficiency of the dye-sensitized solar cells can be increased clearly under the condition of same light intensity.

Description

technical field [0001] The invention relates to the application of a colloidal photonic crystal film, especially in the application field of selective utilization of sunlight, and specifically relates to a preparation method of a full-visible light concentrator including a curved surface photonic crystal film structure. Background technique [0002] With the consumption of non-renewable energy such as coal, oil, and natural gas, the energy crisis has gradually emerged. Therefore, the use of new energy such as wind energy, water energy, and solar energy has long been a research hotspot. Among them, solar energy is a clean and renewable energy source, and its utilization research has attracted more and more attention from governments and researchers in various countries. After nearly half a century of development of solar cells, the highest photoelectric conversion efficiency of solar cells is about 42.8% (Science 2007, 317, 583-584.), but because of the complicated manufactur...
