Morphology
The compound is compositionally built from the element 'selenium' and the device 'cell', so a learner who knows those meanings can infer it is a cell/device that uses selenium to produce electricity (in this case photoelectric conversion). Although somewhat technical, the relation is literal and follows normal noun + noun naming patterns, making the sense directly derivable.
Etymology
Selenium cell comes from old light meters that used a thin strip of the element selenium inside a small cell; when light hit the strip it made an electric signal. That's why a selenium cell means 'a device that changes light into electrical energy'.
