太陽光発電パネルを用いた産業機器駆動の可能性 : 積層型圧電アクチュエータの変位

Abstract

This paper describes a feasibility of industrial application of a solar cell module. Although the solar cell becomes popular, the power generated by the solar cell is several kW/m2, which is not suitable for industrial application. A piezoelectric actuator, which is deformed by the applied voltage, is a small capacitive load. A 120 cm2 solar cell module is used to drive a light capacitive load. The energy generated by the module is directly applied to the piezoelectric actuator. Sunshine is simulated by a light which is applied to the solar cell module. The voltage, current, charge, and deformation of the piezoelectric actuator are measured. Under the experimental conditions, the voltage, charge, and deformation of the piezoelectric actuator are almost proportional to the input power of the light.
