<p>A window is provided comprising a front pane (12) and a rear pane (14) defining a space therebetween, and at least partially transparent liquid (26) disposed within the space. The liquid has a refractive index so close to that of the front pane that a majority of light impinging the front pane will pass therethrough into the liquid. A window further comprises at least one PV cell (18) disposed in the space so that at least a first portion of light that passes through the front pane into the liquid is directed to the PV cell, optionally by a light-ray separator (22) disposed with the space, for conversion of the first portion of light into electrical energy.</p> |
