With all of the increased atten tion being given to solar |X)wer today, few people realize that t)ne of the llrst successful ap plications of solar energy ikcui- red 25 years ago this month. T.M. Graham Southern Hell District tnanager said that the first successful test of solar energy for telecommunications began on October 4, 1955. Hell V l aboratories, the Bell Systetn’s research and development unit, teamed w ith Srmthern Hell to use pole-mounted sttlar batteries to power rural telephone lines near .Americus, Georgia. Graham explained that the in vention of the solar cell and the solar battery were by-products of Hell labs’ pioneer research in semiconductor technology, the 9 same type of research which led to Bell Labs’ invention of the transistor. Bell Labs scientists. Daryl Chapin, Calvin Fuller, and Cierald Pearson found that sunlight energy striking wafer- thin silicon material (same substance as common beach sand) relea.ses electrons in the ^silicon that could then be ca|v ^tured in the form of electrical current.
