Dispersion photovoltaic power generation system

Abstract

The invention discloses a dispersion photovoltaic power generation system. The system comprises a dispersion prism used for dispersing the sunlight into the scattered light different in spectral range; and a photovoltaic power generation device used for respectively receiving the scattered light different in spectral range. The solar energy is provided with the full-spectrum light, and the light is dispersed by the dispersion prism. The dispersed light is divided into multiple wave bands. For different wave bands, photovoltaic power generation devices of different maximum quantum efficiencies are selected for power generation. Therefore, the light energy is maximally utilized and converted into electric energy. As a result, the light energy is converted into the electric energy to the maximum extent.

Description

technical field

[0001] The invention relates to the field of photovoltaic technology, in particular to a dispersion photovoltaic power generation system. Background technique

[0002] Using the photovoltaic effect to convert light energy into electrical energy is the basic principle of solar cells. The solar cells connected in series are protected by encapsulation materials to form a photovoltaic module with photovoltaic power generation effect. The existing crystal-silicon double-glass module uses coated low-iron tempered glass as the front cover, EVA and POE as the packaging material, and TPT as the rear cover. Through high-temperature lamination molding, a photovoltaic glass-encapsulation from top to bottom is obtained. Typical crystalline silicon photovoltaic modules with film-cell-encapsulation film TPT structure.

[0003] However, since sunlight is full-spectrum light, and photovoltaic modules only absorb light energy in a specific spectrum and convert it into electri...
