Optoelectric nuclear batteries with tritium?

[Gamba93]

According with this article http://en.wikipedia.org/wiki/Optoelectric_nuclear_battery

Can it be possible to make a similar battery but filled with tritium and coating or painting the photovoltaic surface with luminiscent substance as is done with tritium keychains?

Then, its possible to regenerate tritium from it's decay product Helium-3 bombarding it with neutrons.

The amount of energy produced by tritium is pretty tiny. What are you hoping to power with it?

Recharging it with neutrons would not be very practical compared to just replacing/refilling the tritium created by conventional means.
