Description

Technical Field

[0001] The utility model relates to the technical field of double-sided solar cells, in particular to a double-sided photovoltaic device and a photovoltaic component array having the same. Background Art

[0002] In addition to absorbing sunlight on the front side, the back side of the bifacial solar cell module can also absorb radiation, which can bring significant efficiency gains to the solar cell module. Bifacial solar cell modules are an important research trend in the existing photovoltaic technology field. When bifacial solar cell modules in the existing technology are used in the agricultural field, in order to reduce the footprint, it is usually expected that the bifacial solar cell modules can be installed vertically; at the same time, in order to reduce the impact on the normal growth of crops in the area where the solar cell modules are installed, and to ensure that crops can receive sunlight at all times in all areas where bifacial solar cell modules are installed, the bifacial solar cell modules need to be designed with appropriate installation positions and directions according to local conditions. In the northern or southern hemisphere, the sunlight at noon comes from due south or due north, and the intensity of the sunlight is the highest at this time. If the installation position or direction is not appropriate, the light irradiated on the module will be reduced, which will lead to lower power generation efficiency of the solar cell module during the noon period.
