ABSTRACTWe discuss recent advances in reflective holographically-formed polymer dispersed liquid crystal materials in the context of their suitability for reflective display applications. A dual-domain phenomenon resulting in a broadened reflection peak is presented. A simple phenomenological model is developed to explain this unusual effect The effect of monomer functionality on the reflectance characteristics of these materials is also discussed. Monomers of effective functionality ∼4.5 yield the brightest holograms, however, the data suggests that these systems are currently far from optimal.

Solar charge controllers are currently a necessary piece of equipment when utilizing the energy from a photovoltaic system for charging purposes. However, a standard solar charge controller available today includes some drawbacks that may be crucial for specific applications. An alternate method of regulating energy from a photovoltaic panel can be accomplished by utilizing polymer-dispersed liquid crystal (PDLC) technology. Combining a solar panel with a proper PDLC material allows the input into the photovoltaic panel to be controlled. This method of power regulation can lead to increased efficiency, reduced cost, reduced weight, and increased safety when compared to a standard solar charge controller.
