Abstract
For cases in which a robot with installed solar cells and a sensor operates in a nuclear reactor building or in space for extravehicular activity, we require elastic and extensible solar cells. More than two different types of sensing are also required, minimally with photovoltaics and built-in electricity. Magnetic compound fluid (MCF) rubber solar cells are made of rubber, so they are elastic and extensible as well as sensitive. To achieve flexibility and an effective photovoltaic effect, MCF rubber solar cells must include both soluble and insoluble rubbers, Fe3O4, TiO2, Na2WO4∙2H2O, etc. On the basis of this constitution, we propose a consummate fabrication process for MCF rubber solar cells. The characteristics of these cells result from the semiconductor-like role of the molecules of TiO2, Fe3O4, Ni, Na2WO4∙2H2O, polydimethylsiloxane (PDMS), natural rubber (NR), oleic acid, polyvinyl alcohol (PVA), water and magnetic cluster involved in the MCF rubber. Their tendencies can be deduced by synthesizing knowledge about the enhancement of the reverse-bias saturation current IS and the diode ideality factor N, with conventional knowledge about the semiconductor affected by γ-irradiation and the attenuation of the photon energy of γ-rays.

Summary
Elastic and extensible solar cells are highly desirable in robots with installed solar cells and a sensor operating in a nuclear reactor building or in space for extravehicular activity. We propose elastic and extensible solar cells with sensing capabilities for force and γ-ray irradiation, and with built-in electricity, built-in voltage and built-in current [1]. By applying both DC electric and magnetic fields to a water-soluble rubber latex such as natural rubber (NR) or chloroprene rubber (CR) compounded with our developed magnetic responsive fluid, a magnetic compound fluid (MCF), the MCF rubber liquid can be electrolytically polymerized to form a solid [2]. We investigated the photovoltaic and γ-irradiation effects on the MCF rubber using knowledge previously obtained on MS, MIS and MOS [8]-[17]
