Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

The feasibility of using solar cells for post-detonation monitoring, and more broadly, gamma-ray monitoring, is evaluated using Monte Carlo simulations and experiments in this work. We measured the short-circuit current Isc response of commercial silicon (Si) solar cells to 137Cs and 60Co gamma rays. A clear response of both mono- and polycrystalline Si solar cells to 137Cs and 60Co gamma rays was obtained in good agreement with the simulations. Radiation effects in solar cells due to accumulated gamma-ray dose were noticed as the drop in Isc and open-circuit voltage Voc. The atomic displacement cross section of the produced secondary fast electrons and nonionizing energy loss (NIEL) concepts were revisited to understand the principal gamma-radiation damage mechanism in solar cell devices. Analytical computations of and NIEL of electrons convoluted with simulated Compton electron distributions in Si enabled a fundamental understanding of the gamma-radiation effects and recovery mechanism in solar cells, further supporting the experimental results. Different from the ionization effects in the polymer and glass layers of a solar cell/panel, displacement damage in the Si p-n layer from gamma rays or fast electrons is much less than that from massive particles, which directly affects the charge collection performance fundamental to solar cell operation.
