    Abstract In order to apply for radiation dosimetry in decommission of the TEPCO Fukushima Daiichi nuclear power plant, we develop the dosimeter based on CuInGaSe (CIGS) solar cell which have very high radiation tolerance, stable detection of radiation over long periods in a high-dose environment is expected. In this method, radiation generates electron–hole pairs in the absorber layer of the CIGS solar cell due to ionization, and the resulting current is measured as the detection signal. The current response of CIGS solar cells in a gamma-ray environment and characterize the dosimeter behavior. The CIGS solar cell device exhibits stable operation without degradation even in a Co-60 gamma-ray environment of 1 MGy, and its detection characteristics allow measuring dose rates from 100 mGy h −1 to 100 kGy h −1 with an approximate resolution of 10 mGy h −1 with a fast response of approximately 2 ms.

    Decommissioning the accident at the Fukushima Daiichi nuclear power plant, research and development of solar cell-based radiation detection devices (SRDs) for reactor-internal radiation monitoring systems is underway. SRDs use the principle of electron-hole pairs generated by the energy of the incident radiation to output a current to an external circuit by the built-in-potential. InGaP, CIGS, CdTe and HOIP have been selected as candidates for radiation tolerant solar cells for use in high radiation environments. This report presents the development of a radiation detection system using InGaP solar cells as an example, the development of a dynamic range estimation method using visible light and work on the detection of neutron radiation.

    We proposed a compact and radiation-tolerant dosimeter without power supply using the solar cells such as CdTe, Cu(In,Ga)Se2 (CIGS), and InGaP solar cells. In the CdTe solar cells, linear increase in current due to 60Co gamma-ray absorption was confirmed. The change rate of current density increased with increase in the reverse bias voltage, probably due to the increase in the depletion layer width.
