Light ray-adjustable non-light tight membrane photovoltaic component and manufacturing method thereof

Abstract

The invention discloses a light ray-adjustable non-light tight membrane photovoltaic component, which is used for solving the problem that the light ray transmission intensity of the conventional non-light tight membrane photovoltaic component cannot be adjusted optionally according to a user requirement. The photovoltaic component also comprises an inverse dimming liquid crystal unit positioned between a back electrode and back plate glass, wherein the back electrode and the back plate glass are bonded respectively through adhesive-lined materials on both sides of the inverse dimming liquid crystal unit. The embodiment of the invention also provides a method for manufacturing the light ray-adjustable non-light tight membrane photovoltaic component. The photovoltaic component comprises the inverse dimming liquid crystal unit of which the internal liquid crystal droplet refractive index varies under the condition of an electric field, so that the light ray transmission intensity of the non-light tight membrane photovoltaic component can be varied through the magnitude of an applied electric field and the aim of realizing adjustable light ray transmission intensity of the photovoltaic component is fulfilled. Therefore, different requirements of a user on adjustable refractive index of the photovoltaic component are met.
