Abstract

We have constructed a hypothetical charge pump which converts solar energy into DC electricity. The output is generated by cyclic changes in the capacitance of a circuit, which transfers charge from a low to a high voltage. The electric field across the capacitor must be of the order of 10⁸ Vm^-1 to compete with efficiencies of photovoltaics. We have modeled the output using a liquid crystal elastomer as the working substance. Efficiencies of 1-4% are obtained, and are enhanced by careful choices in the capacitor geometries and the operating voltages of the charge pump.
