Science Of How Solar Panels Work

These cells are made of semi conductive materials most often silicon a material that can conduct electricity while maintaining the electrical imbalance needed to create an electric field.

Science of how solar panels work.

In 1839 french scientist edmond becquerel discovered that certain materials would give off sparks of electricity when struck with sunlight. Step by step overview. Solar panels actually comprise many smaller units. It s an idea that has been around for well over a century.

Solar pv panels are comprised of many small photovoltaic cells photovoltaic meaning they can convert sunlight into electricity. Solar panels work by absorbing sunlight with photovoltaic cells generating direct current dc energy and then converting it to usable alternating current ac energy with the help of inverter technology. The first photovoltaic pv cells made of selenium were. In 1839 henri becquerel noted that silver and platinum electrodes.

Solar photovoltaic pv panels are based on a high tech but remarkably simple technology that converts sunlight directly to electricity. In fact a solar panel is comprised of an array of smaller units called photovoltaic cells which are the. Solar panels generate electrical current by exploiting a phenomenon first described more than a century ago by a french physicist. Researchers soon discovered that this property called the photoelectric effect could be harnessed.
