This disclosure provides systems, methods, and apparatus for directing light incident on a window towards photovoltaic cells. In one aspect, photovoltaic cells are arranged the perimeter of a window pane. The pane also includes light-turning features that divert a portion of the incident light towards the photovoltaic cells on the perimeter, while simultaneously transmitting a portion of incident light through the pane. The dimensions and arrangement of the light-turning features can be adjusted to change the amount of light diverted to the photovoltaic cells, and consequently the amount of light transmitted through the glass.
