Description

A light-transmitting composite photovoltaic structure

technical field

The invention relates to a photovoltaic structure, in particular to a light-permeable composite photovoltaic structure.

Background technique

Buildings that integrate photovoltaic systems are one of the effective ways to achieve low-energy buildings. Collecting natural light on building facades or roofs and converting it into electricity through photovoltaic materials is a way to efficiently use energy. Among the various forms of solar energy, compared In terms of direct lighting, the effect is the highest because there is no conversion of energy forms. Therefore, materials with both lighting and power generation effects have a good application space in architecture. The traditional photovoltaic panels or light-transmitting photovoltaic panels applied to the top of the building have the following defects:

Traditional photovoltaic panels are opaque and can be used to generate electricity when applied to the top of a building, but cannot receive sunlight.

Another traditional thin-film photovoltaic material has low light transmittance. This thin-film photovoltaic material achieves the purpose of controlling its own transmittance by controlling its micropores, but its photoelectric conversion efficiency is low. Moreover, thin-film photovoltaic materials are semi-transparent materials with low light transmittance. As a uniform light-transmitting medium with low light transmittance, it is not ideal to be directly used as building lighting materials.
