BIPV is the integration of photovoltaic buildings, also known as photovoltaic curtain wall systems. It is a new functional curtain wall that combines the functions of power generation, sound insulation, heat insulation and decoration. The new functional curtain wall that combines optoelectronic technology and curtain wall technology represents a new direction for the development of curtain wall technology. In addition to the performance of ordinary curtain wall, the photoelectric curtain wall has the function of converting light energy into electric energy. The key component of the photoelectric conversion wall to achieve photoelectric conversion is the photoelectric template. When it realizes photoelectric conversion, it does not consume precious mineral energy, does not emit harmful gases such as sulfur dioxide, does not generate noise, and has no waste residue. It is a clean energy source.
