A twin high-power concentrating solar cell module

Abstract

The invention discloses twin highly concentrated light solar cell modules. The twin highly concentrated light solar cell modules comprise a compound eye type lens condenser and a circuit board, wherein the circuit board is provided with photovoltaic cell crystals, the compound eye type lens condenser comprises multiple blocks of planar-arrayed condensing lens, the photovoltaic cell crystal is correspondingly arranged below each condensing lens, a condensing sphere is arranged between each condensing lens and each photovoltaic cell crystal, a structure formed by each condensing lens and the corresponding condensing sphere is of an axial symmetric structure, the spherical center of the condensing sphere and the axial center of the condensing lens are arranged on the symmetrical axis. Through two-time condensing, the light path is reduced, and the whole thickness of the condensing module is reduced; through a mode of light ray equal ratio compression numerical value solution, the energy of a light spot is uniformly distributed, the transverse current in a battery is avoided, the conversion efficiency of the module is improved, the battery efficiency attenuation is slowed down, and thus, the high-efficiency condensing module is obtained; and moreover, the system tolerant ability is improved, the accuracy requirement is reduced, and the fabrication cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of solar energy utilization, in particular to a twin high-power concentrating solar cell module. Background technique [0002] Concentrating photovoltaic power generation technology is recognized as an effective way to reduce the cost of photovoltaic power generation. At present, a complete concentrated photovoltaic power generation system mainly includes several parts such as compound-eye concentrated solar cell modules, solar trackers, and electric energy storage or inverter equipment. As a photoelectric conversion component, the compound eye concentrating solar cell module is mainly composed of a compound eye lens concentrator and a circuit board installed with a photovoltaic cell chip.

When in use, the condensing lens is basically facing the direction of sunlight through the sun tracker, and then the sunl...

AI Technical Summary

Problems solved by technology

[0008] 1. Most of the current concentrating components are large in size and difficult to miniaturize, which not only increases the cost of packaging, but also increases the difficulty of transportation and installation

[0009] 2. The uneven distribution of light intensity after concentrating light will generate lateral current, which reduces the fill factor of the module and reduces the photoelectric conversion efficiency
