Pretty radical design. What are the solar cells on the back for?

"The heat produced by the sun on the large glazed dome of the cockpit is cooled when stationary by a temperature control system powered by a solar panel on the rear of the car."

Seems the polycarbonate canopy basically is a mobile hothouse. Wiki says the panels supply the AC and the electronic locking system (keycard).
Indeed a radical concept and quite impressive stats, especially for the time. Also I think i recognise some design features that were "borrowed" by other concept cars later on
