A solar energy collector and thermal storage device for placement in a building's exterior architectural opening is provided, having an insulating cavity including a first lite on the device exterior side and a second lite spaced inwardly therefrom, defining a depth of the insulating cavity, and being substantially filled with an insulating gas. A provided thermal storage cavity includes the second lite and a third lite spaced inwardly therefrom, defining a depth of the thermal storage cavity which is at least the same size as the insulating cavity depth, and is substantially filled with a thermal storage medium, which is a hydrogel adhering to the second lite and the third lite and having cohesion characteristics such that it is self supporting and maintains its shape within the thermal storage cavity. A low-emissivity coating disposed on the insulating cavity side of the second lite inhibits exterior thermal radiation transfer. |
