Abstract

The invention discloses perovskite quantum dot glaze, photovoltaic glass, a preparation method of the photovoltaic glass and a photovoltaic module. The perovskite quantum dot glaze comprises a transparent glaze and a quantum dot, the quantum dot has a core-shell structure, the inner core is a perovskite quantum dot, the outer shell is a high-temperature-resistant coating layer, and the high-temperature-resistant temperature of the coating layer is not lower than 800 DEG C; the mass ratio of the perovskite quantum dots to the transparent glaze is 1: (10-100). The perovskite quantum dot glaze can be used for preparing a photovoltaic glass glaze layer, and the prepared glaze layer can absorb short-wave light and convert the short-wave light into long-wave light which can be absorbed by a photovoltaic module, so that the light utilization rate and the power generation efficiency of the photovoltaic module are improved.

Description

technical field [0001] The invention belongs to the field of photovoltaic components, and in particular relates to a perovskite quantum dot glaze, photovoltaic glass and a preparation method thereof, and a photovoltaic component. Background technique [0002] The temperature adjustment in the building consumes a lot of energy. When using traditional energy to control the temperature adjustment, it not only consumes fossil energy but also causes environmental pollution. With the continuous development of new energy and the increasing demand for urban energy conservation, emission reduction, and green environmental protection, building integrated photovoltaics has become an inevitable trend, and it has increasingly become a new scenario for solar power generation. [0003] Building Integrated Photovoltaic (BIPV) is a new concept of applying solar power generation. The combination of photovoltaic arrays and buildings is an advanced form of BIPV, which has high requirements for...
