People have been putting in efforts to improve a different source of energy by harnessing the sun’s potential, all while continuing the fight against the bad effects of global warming. In order to power their businesses and their homes, many people use crystalline silicon, which is a particular type of solar panel, today. However, massive production of crystalline silicon solar panels is not likely to occur because of the high installation cost of this type of solar panel. Hence, people living in remote areas will not be able to benefit from this source of renewable energy. But worry not for various technological advancements have geared towards developing a cheaper line of solar panels.
Thin solar panel film is the new trend in the solar power industry today. This new type is believed to be the gateway for a more competitive solar panel industry, especially in the domestic range. Thin solar panel film consists of one micron thick of light-absorbing layers, as compared to silicon-wafer cells. This makes this type of solar panel easy to use, lightweight and very durable as compared to other types.
A lot of reasons serve as the basis why thin solar panel films are better to use than traditional solar panels (monocrystalline and polycrystalline). Their thickness and their cost of production are the main bases of the difference between the two types. Thin slices of crystalline silicone are used to produce traditional photovoltaic panels. The materials used to produce this type of solar cells are actually costly. Because of this, it is unlikely for this device to go into mass production. On the other hand, thin-film cells are very cheap to produce. Since they only entail one micron, they are cheaper as compared to traditional solar cells. Traditional solar panel cells are much thicker than thin-film cells, so they are harder to produce and distribute.
Three basic types divide the solar panels of today. These types are the amorphous silicon thin-film, cadmium telluride thin-film and copper indium gallium diselenide (CIGS) thin-film. Obviously, the subtypes of thin-film solar cells depend on the semiconductor used to create the solar cell. Amorphous silicon type and traditional solar cells use the same concept in terms of production. Their only difference is that the silicon used to create solar panels is deposited onto flexible plastic or metals. Though this subtype of thin-film is less efficient, it is more cost-effective.
The second thin-film cells types is known as the cadmium telluride thin-film cells. This type is less popular than the other subtypes it this new solar power technology. It is the least cost-efficient among the three types, even if it is the cheapest. It is also not as favored as the other types because a toxic material is used to manufacture this solar cell. More researches are being undertaken to study the effects of this material when used for a long period of time. This type of thin-film cells generally has only a 15% efficiency.
The last subtype of thin-film cells is the copper indium gallium diselenide. In terms of cost-effectiveness and energy efficiency, this subtype is known to be the most promising. It has 99% light-absorption capacity and its conversion efficiency is proven to be stable over time.
With the continuous development in thin solar panel film and in the solar power industry, it won’t be long until everyone enjoys the sun’s power and prevent further damage that greenhouse gases bring.
