Solar photovoltaic manufacturing basics include several solar technologies, all of which are aimed to make the solar energy conversion process more efficient. It is well known that photovoltaic solar modules are designed to convert sunlight into electrical energy. The smallest element in a PV module made of various semiconductor materials is known as a cell. These are small, typically less than the thickness of four human hairs devices that are usually expected to produce about 1 or 2 watts of power.
One of the technologies used in solar module manufacturing is to half-cut solar cells. In some sources, such modules are referred to in different ways, for instance, dual cells or split cells. These modules are designed with twice as many half-sized cells as the other types, regardless of the name.
People may wonder why the solar panel manufacturing process may need to cut cells in half. The answer is rather straightforward; cutting solar cells in half results in up to a 3% increase in energy efficiency. The efficiency boost leads to better production per m², higher output and lesser power losses.
The Perks of PERC Technology
PERC is another technology widely used in solar panel manufacturing.
Invented in Australia in the 1980s, the technology has gained popularity only in the past few years. Standing for “Passivated Emitter and Rear Cell”, the term refers to solar modules with an additional dielectric passivation layer, a reflective rear surface and aluminium contacts. Due to the reflective surface, absorbed sunlight rays instead of being wasted, get another chance to be absorbed and converted into extra energy.
Despite a bit complex structure, PERC technology helps the manufacturers to produce solar modules with higher power capacity. Today, the greatest advantages of PERC cell technology with the help of PERC photocells, it is possible to produce modules with up to 370 W. Such modules work equally well both in sunny weather and in relatively low light.
There are already other technologies on the market today aimed at improving the energy efficiency of solar panels. However, PERC technology is leading both in the world and in the local Armenian market. Armenian-made solar panels are manufactured according to international standards, standing out due to their high efficiency and competitive prices.
