1. A display element comprising:

  • a first layer at least partially transmissive of light;

    a second layer at least partially reflective of light, the second layer spaced from the first layer, the second layer selectably movable between a first position in which the display element has a first reflectivity and a second position in which the display element has a second reflectivity, the first reflectivity greater than the second reflectivity; and

    a photovoltaic element formed on the first layer or the second layer or formed between the first layer and the second layer, the photovoltaic element at least partially absorptive of light and configured to convert a portion of absorbed light into electric energy at least when the second layer is in the second position.
