6 FAQs about [Solar panel photovoltaic back contact]
What is a back contact solar cell?
These lines are actually the front contacts that collect the electricity generated by the panel. Now, imagine a solar cell without these lines on the front. This is what we call a Back Contact (BC) solar cell. In BC solar cells, all the electrical contacts are moved to the back of the cell, allowing the front to capture more sunlight.
What is an interdigitated back contact solar cell?
Interdigitated back-contact (IBC) is a solar cell in which the entire emitter is located at the rear of the cell. IBC solar cells are also known as back junction or point contact solar cells. Historically, the IBC solar cell was first developed at Stanford University for concentrating solar photovoltaic application .
What are the benefits of a back contact solar cell?
An additional benefit is that cells with both contacts on the rear are easier to interconnect and can be placed closer together in the module since there is no need for a space between the cells. Back Contact Solar Cell as used in commercial production. 1. P. J.
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.
Are back-contact solar cells better than conventional solar cells?
The back-contact silicon solar cell structures have demonstrated superior performance compare to that of conventional silicon solar cells. While silicon solar cells are established technology, there is still much potential for improvement, to drive down the cost while increasing conversion efficiency.
Why do solar cells have a back contact structure?
In addition, the rear-contact design structure allows bigger and wider contacts to be used since it does not face the sun. This tackles one of the main issues in silicon solar cell design, known as resistive loss. Furthermore, the absence of a front contact grid makes the-back-contact solar cells suitable for concentrating application.
