6 FAQs about [Solar Cell Structure IBC]
How do IBC solar cells work?
Collected electron flows from p + metal contacts to the load, generating electricity, and then going back to the IBC solar cell through the n + metal contact, ending that particular e-h pair. After understanding more about IBC solar cells, it is important to compare them to the well-known traditional Al-BSF technology.
Why should you choose IBC solar panels?
With an increased efficiency for IBC solar cells, an IBC solar panel can be manufactured without space between cells, further increasing the power output per square meter for a single module. This makes IBC solar cell technology more compelling for applications with limited space.
What is the performance of the IBC solar cell?
Performance comparison between our IBC and recent cells with back contact architectures. The Voc of the IBC solar cell is 693.1 mV when illuminated from the front side. The recombination losses mainly reduce the Voc and therefore the cell efficiency.
What is Interdigitated Back Contact (IBC) solar cell technology?
One of the most innovative methods to have proven higher efficiencies using crystalline silicon (c-Si) cells is the Interdigitated Back Contact (IBC) solar cell technology.
What is IBC solar cell restructuration?
IBC solar cell restructuration places frontal metal contact on the rear side of the cell, eliminating shade caused by the busbars. By doing this, IBC solar cell increases the photon effective absorption which results in reduced power losses and several other benefits.
