Author: We live in a very energy conscious age. A brief look at the media is enough to confirm this, everywhere you look headlines talk of pollution, dwindling oil reserves, global warming and carbon footprints. All of which has lead to a scramble for alternate energy sources. The most vaunted of those has been energy from the sun and in order to fully understand it one needs to examine the development of technology for photovoltaic solar panels.
If you think about it the sun has always been a no brainer for energy. As the closest star to the earth is has provided light, seasons and the ability to nurture life on the planet. Its no surprise that the ancient Egyptians used to worship it for its perceived powers.
Flash-forward to many centuries later and scientists began to think of ways that its power could be harnessed, the key was to find a way to convert, store and use that energy as needed. Early models of solar power were optimistic at best or downright unwieldy.
In 1816 Robert Stirling applied for a patent for his economizer machine, a primitive type of heat engine. It was only in 1839 when French scientist Edmond Becquerel discovered photovoltaic cells while experimenting with an electrolytic cell. He discovered that the electricity generation of the cell increased by a significant amount when the cell was exposed to light.
That was the catalyst that led to the breakthrough. Other scientists were able to piggyback onto his discovery and make improvements. Due to the accelerating effect of modern technology three American scientists in 1954 invented a silicon photovoltaic cell that was capable of converting the suns energy into enough electrical power to run everyday appliances. Currently solar panels are used on a commercial basis and are used to power everything from appliances to skyscrapers.
