Sealed photovoltaic module

Abstract

The invention discloses a sealed photovoltaic module. The sealed photovoltaic module comprises a base, a rotary shaft, a photovoltaic module, a guiding rail and locking pins, wherein the photovoltaicmodule comprises back contact solar batteries, a circuit substrate, an optical glass plate, a silicon nitride antireflection film, a silica gel heat dissipation cushion and a heat dissipation plate; the rotary shaft is arranged at one end of the base; the photovoltaic module is rotationally connected with the base through the rotary shaft; the arc-shaped guiding rail is formed in the other end ofthe base; grooves are formed in the two sides of the photovoltaic module; multiple through holes are formed in the guiding rail at equal spacings; the locking pins arranged on the guiding rails pass through the through holes to be inserted into the grooves; a sealed cavity is formed in the photovoltaic module; the back contact solar batteries and the circuit substrate are arranged in the sealed cavity, and the interior of the sealed cavity is filled with a sealing agent; the optical glass plate is arranged on the upper part of the photovoltaic module; the upper surface of the optical glass plate is coated with a layer of the silicon nitride antireflection film; and the heat dissipation silica gel cushion is positioned between the sealing agent and the heat dissipation plate. The sealed photovoltaic module disclosed in the embodiment is high in power generation efficiency, high in dampproof effect and capable of avoiding electrode corrosion.

Description

Technical field [0001] The invention relates to the field of solar photovoltaic modules, and in particular to a sealed photovoltaic module. Background technique [0002] With the development of society and economy, traditional energy is declining day by day. There are 2 billion people in the world who do not have access to normal energy supply. The whole world has set its sights on renewable energy, hoping that renewable energy can change the energy structure of mankind and maintain Long-term sustainable development. Solar energy has become the focus of people's attention with its unique advantages. As a rich renewable energy resource, solar energy is pollution-free, cheap, and can be used freely by humans; [0003] Solar cell modules have always been a research hotspot of people. The poor heat dissipation performance of existing heat-dissipating solar cell modules and low battery photoelectric conversion efficiency are problems that need to be solved. In rainy weather, solar cell...
