宇宙用太陽電池に対し、電子線照射と「その場」電流・電圧測定が行える装置の開発を行った。この装置は大阪府立大学放射線研究センターにある電子リニア加速器に設置され、6MeVから12MeVの電子線を-196$$^{circ}$$Cから100$$^{circ}$$Cの温度範囲で照射することが可能である。また、太陽電池の電流・電圧特性もこの温度範囲で測定可能である。まずは宇宙用単結晶Si太陽電池の電流・電圧特性を室温又は低温で測定し、温度可変機構が正常に動作することを確認した。また、10MeV電子線を室温で照射して電流・電圧測定を行い、この結果を1MeV電子線あるいは10MeV陽子線照射の結果と比較した。

We developed an apparatus for electron irradiation and in-situ current-voltage (I-V) characteristics measurements for space solar cells. The apparatus was interfaced to an electron linear accelerator at Radiation Research Center of Osaka Prefecture University. By using this apparatus, the electron irradiation with the energies from 6 MeV to 12 MeV can be performed at various temperatures from -196 $$^{circ}$$C to 100 $$^{circ}$$C. In-situ I-V characteristic measurements are also possible at the temperature from -196 $$^{circ}$$C to 100 $$^{circ}$$C. As a first demonstration using this apparatus, we performed two experiments. First, I-V characteristics of a Si solar cell were measured at room temperature and at low temperature. Secondly, the Si solar cell was irradiated with 10 MeV electrons and I-V characteristics were measured at room temperature. The experimental result was compared with those for 1 MeV electron irradiation and 10 MeV proton irradiation.
