You'll need to series stack a couple of silicon photodiodes for that to work.

The photocurrent will need to be around 50 microamps or so to keep the output resistance low enough.
A shunt capacitor may also be required.

It is a shame that the original spacing for the batteries was so tight. I
realize the need to keep the leads short, but it makes it difficult to

Efficiency as measured by voltage transfer, it would be interesting to--
compare power transfer efficiency. With 20mA on the driven LED is it
possible to get even a few microamps of output current?
