Tubular concentrating photovoltaic cell module

Abstract

The invention provides a tubular concentrating photovoltaic cell module. The tubular concentrating photovoltaic cell module comprises a glass tube, and at least one set of a light concentrating optical system and a photovoltaic cell array, wherein the at least one set of the light concentrating optical system and the photovoltaic cell array are arranged in the glass tube in a corresponding mode. The tubular concentrating photovoltaic cell module is characterized in that the photovoltaic cell array comprises a plurality of photovoltaic cell array units arranged in an array mode, each photovoltaic cell array unit comprises at least one piece of photovoltaic cell and a heat dissipation structure arranged on the back portion of the photovoltaic cell, each heat dissipation structure makes contact with the back portion of each photovoltaic cell in a heat conducting mode and is closely attached to the inner wall of the glass tube, therefore, the heat of the photovoltaic cell array units is dissipated to the glass tube wall which is larger in area, and the heat is transmitted to the external environment of the glass tube through the glass tube wall. The light concentrating optical system reflects the sunlight to the surfaces of the photovoltaic cells. The tubular concentrating photovoltaic cell module is capable of tracking the sun in real time, high in light concentrating multiple, simple in manufacturing, low in cost and suitable for being arranged on all kinds of sites in a large scale.

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 modules are exposed to strong winds and have limited self-supporting capabilities. They also require more bracket steel for reinforcement and installation, resulting in increased system costs
