Window-integrated transparent photovoltaic module

A method of fabricating an electricity generating window, the method comprising:

• forming a photovoltaic device on a top surface of a first glass pane, the photovoltaic device comprising:
• a first transparent electrode layer;
• one or more active layers configured to absorb ultraviolet or near-infrared light and transmit visible light;
• and
• a second transparent electrode layer;
• and
• attaching a second glass pane on top of the photovoltaic device, wherein the second glass pane is separate from the photovoltaic device by a distance.

An electrochromic window comprising:

• a first glass pane including an inner surface;
• a photovoltaic device formed on the inner surface of the first glass pane, the photovoltaic device comprising:
• a first transparent electrode layer,
• a second transparent electrode layer, and
• one or more active layers configured to absorb ultraviolet or near-infrared light and transmit visible light;
• a barrier layer;
• a second glass pane;
• and
• an electrochromic layer between the barrier layer and the second glass pane, the electrochromic layer electrically coupled to the first transparent electrode layer and the second transparent electrode layer.
