Embodiment Construction

[0039] Certain terms are used throughout this document to refer to particular components. As those skilled in the art will recognize, the same components may often be referred to by different names, and thus this document does not intend to distinguish between those components that differ only in name but not in function. In this document, the terms "comprise", "include" and "have" are used in an open form and should therefore be construed to mean "including but not limited to...". In addition, the terms "about", "substantially" or "approximately" that may be used herein refer to industry accepted tolerances for the respective terms.

[0040] In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the apparatus, methods and apparatus of the present invention may be practiced without these specific detail...

Abstract

The invention relates to photovoltaic glass used for a solar cell. A surface of the photovoltaic glass is provided with independent round annular structures which are independent light trap structures. The external diameter of a ring ranges from 0.1 mm to 5 mm, an included angle formed by an inner ring and an outer ring is smaller than or equal to 90 degrees, and therefore multiple reflections and refractions of light rays can be finished in the independent round annular structures. Through adoption of the photovoltaic glass, 99.8% of incident light which enters a glass interface for the first time can be captured, that is, 96% of reflected light which is generated for the first time can be captured and reutilized, and an existing photovoltaic glass product can roughly capture 30% to 40% of reflected light which enters the glass interface for the first time, such that by adopting the photovoltaic glass provided by the invention, more light transmitted through the photovoltaic glass can participate in photoelectric conversion, and the electricity generation rate of the solar cell can be greatly improved.

Description

technical field [0001] The invention relates to photovoltaic glass applied to solar photovoltaic cells, in particular to a photovoltaic glass with independent light trap type and high light transmittance. Background technique [0002] At present, the shortage of energy has become the core problem that plagues the development of countries all over the world. Solar energy is a sustainable green energy that is abundant and does not cause environmental pollution. From a long-term strategic consideration, the development and utilization of solar energy is the sustainable development of all countries. important part. At present, there are two main ways to utilize solar energy around the world: one is to convert solar radiation energy into thermal energy through heat collectors, such as solar water heaters, etc.; the other is to convert solar energy into electrical energy through solar cells, that is, photovoltaic power generation. , such as solar cells, etc. Whether it is a devi...
