Greenhouse solar photovoltaic assembly and manufacturing method thereof

Abstract

The invention relates to the technical field of solar photovoltaic power generation and photovoltaic agricultural technology and discloses a greenhouse solar photovoltaic assembly. The greenhouse solar photovoltaic assembly comprises a transparent pressing plate, a crystal silicon plate and a light-converting back plate, wherein the transparent pressing plate, the crystal silicon plate and the light-converting back plate are sequentially bound together by a binder. The crystal silicon plate includes a plurality of silicon wafers spaced apart from one another. The invention also provides a manufacturing method of the greenhouse solar photovoltaic assembly. The method comprises the steps of horizontally arranging a plurality of silicon wafers at intervals on the light-converting back plate to form the crystal silicon plate, coating the binder among the silicon wafers, coating the binder between the transparent pressing plate and the crystal silicon plate, and covering on the crystal silicon plate. The transparent pressing plate and the crystal silicon plate are arranged at an interval, so that the light transmittance is improved. The light-converting back plate has the scattering function and the light-converting function, so that the sunlight is converted into the light required by the crop growth. Therefore, the effective illumination intensity of the sunlight for the growth of crops in the greenhouse is improved and the sunlight is uniformly scattered. The conditions of the uneven illumination and the shading phenomenon in the greenhouse are avoided. The greenhouse solar photovoltaic assembly is good in light transmittance, light-converting and power generation functions. The greenhouse solar photovoltaic assembly is suitable for being popularized in photovoltaic greenhouses in vast areas of China.

Description

technical field [0001] The invention relates to the fields of solar photovoltaic power generation and photovoltaic agriculture, in particular to a greenhouse solar photovoltaic module and a manufacturing method thereof. Background technique [0002] Greenhouse horticulture is a modern agricultural production method that provides a suitable growth environment for vegetables, flowers and other crops through certain engineering and technical means, so that they can get rid of the shackles of natural climate and traditional production conditions, and obtain high-yield, high-quality, efficient and safe agricultural products. Due to the need to provide crops with suitable and stable environmental conditions such as temperature, light, and humidity, and to provide corresponding environmental control equipment, the energy consumption of the facility horticulture production process is also quite huge. Since it is also necessary to use solar energy, the combination of greenhouse and p...
