If they have a battery that powers the radio for eight months why would the solar cells be necessary?
Sun-Powered Receiver
An experimental pocket-sized radio receiver, powered by energy from the sun, weighs only 10 ounces and will work more than eight months in total darkness without recharging. Developed by General Electric, the set uses a miniature storage battery, four transistors, and seven solar cells. During the day, light rays hit the solar cells which convert the sun’s energy to electrical current. This current powers the transistors and, at the same time, charges the storage battery which takes over at night. Artificial light, such as an ordinary 100-watt bulb, may be substituted for sunlight.

Perhaps they meant that once charged, it could remain in darkness for 8 months until needed and still have sufficient power to run the radio.
