In addition to G.E. having displayed an experimental solar-powered transistor radio in January, at least two other U.S. companies experimented with the idea of powering their transistor

Circa 1962/''63, a nice little 9-transistor solar-powered / battery-powered radio. Measures about 5 x 3 x 1 3/4...

I have three of ''em, green, yaller, and red, and two tube models that used the same case, but of course weren''t able to be solar powered. The Transistor sets are heavy with the steel chassis

A solaristor (from SOLAR cell transISTOR) is a compact two-terminal self-powered phototransistor. The two-in-one transistor plus solar cell achieves the high-low current modulation by a memresistive effect in the flow of photogenerated carriers. The term was coined by Dr Amador Perez-Tomas working in collaboration with other ICN2 researchers in 2018 when they demonstrated the concept in a ferroelectric-oxide/organic bulk heterojunction

His company introduced their first Trans-Solar portable radio in 1957 and sold several models in the next few years. Like the others, this model KP-706 could run on sunlight or batteries.

It was released in 1958, a year after the Hoffman P411 series in 1957. The radio was powered by 12 solar cells and could operate from lamplight as well as direct sunlight or, when neither

Talk about being technologically advanced, this was the most advanced radio you could buy in 1958-59. It''s a wonder Steve Jobs wasn''t involved in it! I was collecting transistor radios before

The proposed method in this paper is by utilizing the transistor waste type 2N3055. The transistor contains photocell that can convert energy radiated by the sun into electricity.
