    you can use either selenium or gold chloride to permanently tone photos. Silver and selenium create a non-reactive (inert for all purposes) compound for conservation purposes...properly stored b&w photos will last as long as their paper base exists, about 3,000 years in the best case scenario.

    Although I never used gold chloride, allegedly it has similar properties. However, i have no idea if these are workable with regards to the solar cell. The reaction time to create these are only a few minutes in the immersed liquid, so they could be bathed in process relatively easily.

    Useful?

    The truth is we are tortured by the truth.
