Types Of Solar Pv Technologies

The two types of solar energy.

Types of solar pv technologies. Types of photovoltaic pv cells all photovoltaic pv cells consist of two or more thin layers of semi conducting material most commonly silicon. Solar pv power was invented in 1839 by alexandre edmond becquerel. Like semiconductors solar pv technology needs purified silicon to get the best efficiency and the price behind pv solar manufacturing is often driven by the crystalline. Several of these solar cells are required to construct a solar panel and many panels make up a photovoltaic array.

At present solar photo voltaic energy is the most popular and most common technology in solar because thermal and concentrated solar technologies have some viability issues such as cost capacity etc. Solar thermal technology harnesses its heat. Pv solar technology generates power because substances like silicon generate an electrical current when they absorb sunlight in a process known as the photovoltaic effect. Amorphous silicon is most developed among the thin film pv.

Solar facts and advice. These different technologies both tap the sun s energy locally and in large scale solar farms. The amorphous silicon is also less prone to overheating which usually decreases the solar cell performance. Photovoltaic technology directly converts sunlight into electricity.

When the semiconductor is exposed to light electrical charges are generated and this can be conducted away by metal contacts as direct current dc.
