The solar glass AR film coating roll coater provided by the utility model can be used for uniformly coating; the industrialization is realized by effectively combining a nanometer technology of a client; the light transmittance of glass can be increased by the produced product; the self-cleaning function can be achieved; the conversion efficiency of a photovoltaic cell can be effectively improved; and the solar reflectivity of the glass surface is reduced, so that the solar transmittance is improved.

Description

technical field [0001] The invention relates to a roller coater, in particular to a solar glass AR film coating roller coater. Background technique [0002] The factors that determine the efficiency of crystalline silicon solar photovoltaic cells are various variables related to light energy conversion efficiency. The most important determinant is the crystalline silicon technology in photovoltaic components, and the second is to protect the photovoltaic glass in photovoltaic components. Since crystalline silicon cannot Exposure to the external environment for a long time, photovoltaic glass is currently one of the best materials to protect crystalline silicon and has a high light transmittance. Therefore, the optical properties of photovoltaic glass are an important variable outside of crystalline silicon technology. However, it is far easier to maintain and improve the optical properties of photovoltaic glass than to develop crystalline silicon with higher conversion rate,...
