A tubular concentrator photovoltaic cell assembly

Abstract

A tubular concentrating photovoltaic assembly, comprising a glass tube (101), at least one group of concentrating optical system (103) correspondingly arranged in the glass tube (101) and a photovoltaic cell array, is characterized in that the photovoltaic cell array includes a plurality of photovoltaic cell array units in array arrangement, wherein the photovoltaic cell array units include at least one photovoltaic cell (104) and a thermal diffusion structure (106) arranged at the back of the photovoltaic cells (104), the thermal diffusion structure (106) and the back of the photovoltaic cell (104) are in heat conduction contact and the thermal diffusion structure (106) is tightly contacted with the inner wall of the glass tube, heat of the photovoltaic cell array units are diffused to the glass tube wall with a large area and is transmitted to the environment outside the glass tube (101) by the glass tube wall; and the concentrating optical systems (103) reflect sunlight to the surfaces of the photovoltaic cell (104). The tubular concentrating photovoltaic cell assembly can track the sun in real time, the condensation multiple is high, the assembly with the low cost can be manufactured simply, and the assembly is suitable for large-scale arrangement of various occasions.

Description

technical field [0001] The invention relates to a tubular photovoltaic cell assembly, in particular to a photovoltaic cell assembly that reduces cost, improves service life and power generation efficiency through multiple light concentration, reliable packaging and high heat dissipation effect. Background technique [0002] Among the many power generation methods, solar photovoltaic power generation is one of the most technologically advanced and promising methods of new energy and renewable energy. A device that converts light energy into electrical energy under the irradiation of sunlight. However, this kind of flat-panel solar photovoltaic cell module adopts the way of direct sunlight irradiation, because the normal light power density is low, so it requires a large number of module cells, and the unit power cost of electric energy conversion is high; in view of this, in order to use Concentrating Photovoltaic-CPV (Concentrating Photovoltaic-CPV) has been developed by us...

AI Technical Summary

Problems solved by technology

However, there are some disadvantages in this production method: (1) Since the cells are thin, the cells are easily broken during the lamination process, and if the size of the photovoltaic cell module is large, the adhesive material during the lamination process will be melted. Bubbles are not easy to discharge, resulting in low yield

(2) The packaging steps are complicated and time-consuming

(3) The lamination process cannot produce curved photovoltaic cell modules, and cannot meet the requirements of special parts in buildings

(4) High labor and energy costs in the packaging process

(5) The bonding material used in the lamination process is prone to discoloration and other problems after long-term sunlight, which reduces the incidence rate of sunlight and seriously affects the power conversion efficiency, and the replacement cycle of photovoltaic cells is correspondingly shortened

(7) The flaky module is greatly affected by the wind, and its self-supporting ability is limited. It also requires more bracket steel for reinforcement and installation, resulting in an increase in system cost
