A smart photovoltaic window is fabricated by Y. Gao, C. J. Brabec, and co‐workers on page 1524 by solution‐depositing a thermochromic VO 2 layer on top of a semitransparent organic solar cell. The window only produces electricity using the visible part of the solar spectrum, and saves energy via intelligently modulating the amount of NIR radiation passing through the window in response to ambient temperature. When the outdoor temperature is higher than the phase transition temperature of the VO 2 , it blocks part of the NIR spectrum, reducing energy consumption from air conditioning. In cold weather, it allows significant NIR to pass through, reducing energy consumption from heating.
