As a new energy application technology integrated with a building, a Building Integrated Photovoltaic (BIPV) technology is widely used. Conventional BIPV technology is typically retrofitted to existing buildings, but installing photovoltaic modules on existing roof or facade walls requires pre-installation of the module support structure, i.e. the rack. This kind of mounting means needs extra support material cost, and the big cycle of the installation degree of difficulty is long, and the installation cost is higher, can destroy original building's waterproof layer and heat preservation moreover, causes some irreversible damage to the wall body. The other BIPV technology is that the photovoltaic module replaces building materials to be used as a part of a building, namely the photovoltaic module is used for manufacturing a roof, an outer wall and a window of the building, although the integration level and the integration degree are high, the requirements on heat preservation, heat insulation, water resistance, safety and fire resistance of the photovoltaic module are high, and therefore the design difficulty is high and the cost is high.

In recent years, photovoltaic and photothermal integrated (PV/T) components are integrated in buildings to form a building integrated photovoltaic and photothermal (BIPV/T) technology, which gives full play to a solar photovoltaic and photothermal comprehensive utilization technology to improve the solar comprehensive utilization efficiency, but most of the technologies exist in a research stage at present, and a certain distance is left from practical application.
