Nano-Efficient Photoelectric Conversion-Based Solar Photovoltaic System and Its Usage in Green Buildings

Abstract

Solar energy is a world-recognized green and pollution-free energy source. Photovoltaic technology based on solar energy has become the focus of new energy development. On this basis, how to improve the energy efficiency of solar energy has become a research hotspot. In this study, the solution method was used, acety-lacetonate was used as the precursor, and the mixture of dodecyl mercaptan (DDT) and oleylamine (OLA) was used as the solvent to obtain CuInS2 nanocrystals with wurtzite structure. Then, the dispersion of organic synthesized CuInS2 nanocrystals was retained, and the organic macromolecules affecting electron transport in the nanocrystals were eliminated. This material was used for the counter electrode of dye-sensitized solar cells. While analyzing the photoelectric characteristics of the nanoelectronic material, the hardware of the photovoltaic solar cell prepared based on the material should be designed, including the selection of the main control unit, the design of the peripheral circuit, the design of the charging and discharging circuit, so as to realize the management of the photovoltaic solar cell. In the test, OLA had an impact on the crystal structure, size, and dispersion of CuInS2 nanocrystals, thereby changing the photoelectric properties of the nanoelectronic materials, which were applied in photovoltaic panels for green buildings. The photoelectric conversion efficiency of CuInS2 nanocrystals after phase exchange in the green build-photovoltaic system was much higher than that of CuInS2 nanocrystals before phase exchange, and even higher than that of CuInS2 nanocrystals calcined at high temperature before phase exchange in the green build-photovoltaic system.
