IBC solar cell technology: What is it?

A new kind of solar panel technology is called IBC, or Interdigitated Back Bontact. The PN junction and metal contact are found on the back of the solar cell, avoiding shielding of the front metal grid electrode. This is the most notable characteristic of the IBC solar cell.

It has a significant short-circuit current, can reduce light loss, and can increase the utilisation rate of incident light. On the back, series resistance is decreased concurrently by the use of optimised metal gate electrodes.

On the front surface, a double-layer SiNx/SiOx film is typically used. This film has excellent passivation properties on the textured silicon surface in addition to anti-reflection qualities. IBC batteries have the most demanding structural design specifications and the most complicated manufacturing process among commercial crystalline silicon batteries.

How does the IBC solar cell system operate?

IBC solar cells are among the most complicated technologies used to make solar panels, but their efficiency numbers cannot be disregarded. In conventional solar cells, energy conversion is accomplished by adding front contacts to the cell.

Photons must be absorbed immediately after striking the cell's surface in order to produce electricity. They are either transmitted or reflected if not absorbed. A loss of light energy has occurred.

IBC cells, on the other hand, operate differently. Because less light is blocked from entering the cell through the front and electrons produced by absorbed photons can still be collected through the rear, moving the contacts to the back of the cell rather than the front increases efficiency. IBC cells should not be disregarded because of their greater efficiency and other benefits.

IBC VS PERC solar panels

Comparison of IBC solar cell technology and PERC technology

The efficiency, temperature coefficient, and photon absorption area of both technologies are higher. By minimising the surface area occupied by the bus bars or metal contacts, PERC and IBC technologies both provide comparable advantages. IBC solar panel technology eliminates the busbar in contrast to PERC technology, thereby increasing the effective surface area for photon absorption.

1. IBC solar panels produce more power and have higher efficiency

In terms of efficiency, IBC technology outperforms PERC technology because PERC technology only achieved a record efficiency of 25.4% while IBC solar panel technology achieved a record efficiency of 26.7%. IBC panels maximize the effective surface area of the solar cells by getting rid of the front metal contacts, which have a tendency to block sunlight. The IBC panels' electrical contacts are situated on the back to effectively and more fully utilize the sunlight that is received.

IBC cell efficiency

IBC panels can now produce more energy thanks to this innovative configuration, which enables them to produce more power even in low-light situations. IBC technology thus establishes a new standard for solar panel efficiency and is an unavoidable option for both residential and commercial installations.

2. IBC solar panels are stronger and more dependable

IBC technology surpasses PERC technology in terms of improving the robustness and dependability of solar panels. IBC solar panels work cooler than conventional panels, making them better suited for hot summer days. The back contact shields the solar cell from environmental elements like heat and moisture, preventing performance degradation over time. IBC panels also lessen the possibility of Potential Induced Degradation (PID), a condition that lowers the output of conventional solar panels. IBC technology ensures maximum efficiency and dependability of solar panels over a long lifetime by reducing the impact of external factors.

3. IBC solar panels are more visually appealing

IBC technology combines beauty and performance seamlessly. IBC panels, as opposed to PERC panels, do not have front metal contacts for a classy and streamlined appearance. For residential and architectural projects where solar panels must seamlessly integrate into the overall design, this feature is especially advantageous. Users can confidently choose solar without jeopardizing the aesthetic integrity of their structures thanks to the ease with which IBC panels can be easily customized to fit a variety of shapes and sizes.

What application scenarios is IBC technology suitable for?

There is a tonne of unrealized potential for IBC technology in various solar energy applications. IBC panels have a wide range of applications that they can be used for, such as rooftop installations, solar farms, and mobile balcony photovoltaic systems, among others. IBC technology is the best choice for use in situations where there is a lack of available space and a high demand for power generation because of its efficiency and flexibility.

Solar panels are evolving with Interdigitated Back Contact (IBC) technology. IBC solar panels are altering how we utilize solar energy by improving its functionality, aesthetics, and dependability. Solar energy is essential to supplying our energy needs and minimizing the harm that other energy sources cause to the environment as technology advances. We now have an easier and more effective way to generate solar power thanks to the use of IBC technology.
