A Brief History of Everything Solar

A Brief History of Everything Solar

Chapin had for several years been experimenting with selenium-based solar cells but was unable to achieve an efficiency above 1% (for comparison, internal combustion achieves around 20%). At the same time, Fuller and Pearson were developing silicon transistors and found that one of these, when exposed to light, generated electricity. The three scientists joined forces and in 1954 presented their ‘solar battery’, powering a small toy windmill and a radio, at an efficiency of 6%. The key to this was their ability to diffuse boron into silicon, a process known as doping. This first solar cell was the size of a small coin, and although not commercially viable, is the basis for solar cell development ever since.
