Photoelectric integration construction material based on dye sensitization solar energy cell

Abstract

The invention discloses an optoelectronic integration building material based on dye-sensitized solar battery, belonging to the field of green building material. The characteristics lie in that: directly smearing nano crystal semiconductor size on an electroconductive substrate used for construction to manufacture plural of semiconductor films, absorbing the dye to manufacture a semiconductor light anode, wherein the catalyst layer of a counter electrode is composed of material playing catalytic role in oxidation reduction of electrolyte; combining the semiconductor light anode and the counter electrode, pouring electrolyte between the semiconductor light anode and the counter electrode, solidifying and adhering, introducing leads out of the semiconductor light anode and the counter electrode to carry out parallel connection, serial connection or the combination of serial connection and parallel connection so as to obtain a large area for manufacturing the optoelectronic building material. The invention has the advantages of simple technique, low cost, sun-shading, light-transmitting and good decoration effect. The optoelectronic material provided by the invention can be used around the clock, discharges no harmful gas, and is energy-saving and environment-friendly. As the cost is about one tenth of that of the silicon voltaic material, the popularizing rate and application range can be greatly enlarged.

Description

technical field [0001] The invention belongs to the technical field of green renewable energy and the field of building materials, and relates to the technical field of utilizing dye-sensitized solar cells and building materials to form an integrated combination to generate electricity and applying it to buildings. Background technique [0002] my country's per capita energy resources are relatively scarce, the utilization rate of green and renewable energy is low, and the greenhouse effect causes environmental damage and pollution. In addition, during the construction and use of buildings, the waste of resources and energy is prominent, and the energy consumption of buildings is serious. Building energy conservation has become a major problem that needs to be solved urgently. [0003] In order to solve the above problems, photovoltaic power generation is combined with buildings, so that building materials and buildings can generate electricity, which not only adds new funct...

Problems solved by technology

[0005] Most of the above patents are related to some building-integrated solar water heaters and building insulation technologies. They only convert solar energy into heat energy and cannot be used to generate electricity.

[0006] In addition, there are reports related to photovoltaic power generation, such as patent: built-in photovoltaic shutter hollow glass, publication number: CN176627; patent: amorphous silicon photovoltaic building integration, publication number: CN201043332 and patent: photovoltaic power generation curtain wall, publication number: CN2703068, etc. , although it can be used to generate electricity, but due to the complex preparation process of silicon solar cells, the price is particularly expensive, and the silicon cells are sandwiched in building materials, which increases the cost of building materials and silicon cells

At the same time, there are also disadvantages such as poor light transmission, single color, inability to freely design, unsightly, large footprint, and heavy building-integrated devices, which hinder the development of building-integrated photovoltaics.
