Reciprocity rules antenna action. I`m not sure electricity through a
solar cell will cause it to emit light.

Electricity does not travel through a void. Fields travel through voids.

A radio antenna is a transducer that converts between r-f fields and r-f
electricity.

A solar cell is a transducer that converts between light fields and d-c
electricity.

Radio waves and light waves are EM fields that differ in frequency.
