## Abstract

Provided herein is a thermal-managed photovoltaic glass glazing panel comprising a photovoltaic glazing a thermal insulation layer coated on the front surface of the photovoltaic glazing, wherein the thermal insulation layer includes a passive radiative cooling coating material; and a sound and thermal insulation module, wherein the sound and thermal insulation module comprises vacuum glazing, hollow glazing or a combination thereof, adhered to the rear side of the photovoltaic glazing. The photovoltaic glazing module of the present invention not only optimizes solar power generation through specific thermal management designs, but also minimizes both heat transfer and noise intrusion to the interior of the building, maintaining a quiet and stable internal ambient environment, minimizing impacts from the external environment.
