Designing Solar Power Supplies for Transistorized Radio Receivers

The development of fully transistorized radio receivers has resulted in units having extremely low input power requirements. Paralleling the growth and improvement of the transistor was the development of the Silicon Solar Cell, a photovoltaic device capable of converting light energy directly into electrical power. It seems natural then, that a compatible system would evolve in which light energy would be used to supply power to transistorized radios via the mechanism of the Solar Cell.
