Because the material has a high absorption coefficient.
Cigs solar panels vs polycrystalline.
Monocrystalline solar panels remained the number one seller in the industry for many decades yet that s no longer the case.
A copper indium gallium selenide solar cell or cigs cell sometimes ci g s or cis cell is a thin film solar cell used to convert sunlight into electric power.
When compared to polycrystalline solar panels monocrystalline panels undoubtedly perform better at low light conditions.
The efficiency of polycrystalline solar panels is somewhat lower but the benefit for customers is that this option is more affordable.
Usually polycrystalline silicon solar cells won t have the corners cut off of them so you won t see the large white spaces on the front of the panel that you see on monocrystalline panels.
In addition polycrystalline solar panels tend to have a blue hue instead of the black hue of monocrystalline panels.
Polycrystalline panels sometimes referred to as multicrystalline panels are popular among homeowners looking to install solar panels on a budget.
The differences between cigs and crystalline solar cells one big difference is that the cigs is more light sensitive and therefore will a 100 watt peak cigs panel produce around 10 15 more power in a year than a 100 watt peak crystaline panel.
Polycrystalline solar panels are also made from silicon.
With solar energy the issue is material.
Polycrystalline solar panels generally have lower efficiencies than monocrystalline options but their advantage is a lower price point.
In recent years polycrystalline silicon solar panels have surpassed monocrystalline to become the highest selling type of solar panel for residential projects.
What should solar panels be made of.
It is manufactured by depositing a thin layer of copper indium gallium and selenium on glass or plastic backing along with electrodes on the front and back to collect current.
Silicon has history on its side but the future may lie in cigs.
Instead of being constructed from solid silicon wafers like mono or poly crystalline solar panels amorphous panels are made by depositing non crystalline silicon on a substrate like glass plastic or metal one layer of silicon on an amorphous solar panel can be as thin.
Thin film requires more space to produce the same power as mono or poly.
You can expect them to last you for as long as 25 years which is why they often come with a long standard performance warranty of up to two decades.
Cigs will start earlier in the morning and stay on for longer in the evening.
Like conventional solar panels amorphous solar panels are made from silicon but they are constructed in a different way.
Monocrystalline solar panels are very durable and long lasting.
