Abstract:
A microelectromechanical systems (MEMS) display element may include a photovoltaic structure configured to generate electric energy from incident light. In one embodiment, the display element includes a first layer that is at least partially transmissive of light, a second layer that is at least partially reflective of light, and a photovoltaic element that is formed on the first layer or the second layer or formed between the first layer and the second layer. The second layer is spaced from the first layer and is 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 is greater than the second reflectivity. The photovoltaic element is at least partially absorptive of light and is configured to convert a portion of the absorbed light into electric energy, at least when the second layer is in the second position.
