So, what common chemicals play a part in solar energy production? Here are a few: Cadmium. Cadmium is the main ingredient of cadmium telluride (CdTe) cells, a type of photovoltaic panels, which convert sunlight directly into electricity. The CdTe cells are the largest type available and are the most widely used thin-molecule commercial product ...
Photovoltaic (PV) cell production also involves the application of dopants, phosphorus, and boron, to create positive (p-type) and negative (n-type) layers necessary for the semiconductor structure. In thin-film solar panels, such as those made from Cadmium Telluride (CdTe) or Copper Indium Gallium Selenide (CIGS), the processes differ.
Solar photovoltaics (PV) employs the photovoltaic effect to produce electricity from solar radiation. A major milestone in the history of solar PV technology is the first demonstration of a practical silicon photovoltaic (PV) cell, at Bell Laboratories in 1953 (Perlin 2004 ), that converted solar energy into electricity.
And as with most forms of manufacturing (even “clean” energy), chemicals are used throughout the process to produce the end product. From solar panel production to the solar conversion process itself, there are a number of common chemicals utilized – some of which may come as a surprise.
The photovoltaic effect is defined as the process that generates either voltage or current when the device (or solar cell) is exposed to a light source of a suitable wavelength. Solar photovoltaics (PV) employs the photovoltaic effect to produce electricity from solar radiation.
Silicon-based cells are the other type of photovoltaic panels on the market, where they have become well-established but with a decline in use recently. These types of cells provide a higher efficiency of energy per size of cell, making them ideal for areas where space is at a premium.
Silicon serves as the foundational material for most photovoltaic cells due to its semiconducting properties, which are essential for converting sunlight into electricity. It is abundant and non-toxic, deriving primarily from sand and quartz.
