IBC Technology vs PERC Technology vs TOPCon Technology

Solar panel production technology has advanced dramatically in recent years, thanks to the introduction of IBC, PERC, and TOPCon technologies. Solar panels have become a more practical and affordable source of renewable energy as efficiency, durability, and overall performance have improved. Let us contrast these three solar cell technologies.

Interdigitated Back Contact, or IBC, is a new type of solar cell technology. The most notable feature of IBC solar cells is that the PN junction and metal contact are located on the back of the solar cell, preventing the front metal grid electrode from being shielded.

PERC (Passivated Emitter and Rear Cell) technology improves conversion efficiency by adding a dielectric passivation layer to the back of the cell.

TOPCon (Tunnel Oxide Passivated Contact) is a tunnel oxide passivated contact-based selective carrier solar cell technology. It is built with an N-type silicon substrate cell architecture. An ultra-thin layer of silicon oxide is formed on the backside of the cell, followed by a layer of doped silicon, which together form a passivated contact structure that can improve conversion efficiency.

Both PERC and IBC technologies improve efficiency by reducing the amount of space occupied by grid lines or metal contacts. While PERC technology only reduces grid lines, IBC technology completely eliminates grid lines, increasing the solar panel's available surface area.

1. IBC solar panels with higher efficiency and power output
Statistically, PERC solar panels have an efficiency of less than 22%, whereas IBC solar panel technology has an efficiency of 22.8%, indicating that IBC technology is superior to PERC technology. IBC panels have a larger effective surface area for solar cells because the frontal metal connection, which tends to block sunlight, has been removed.

2. The low temperature coefficient of IBC solar panels is higher.
IBC solar panels can work more efficiently in hot climates because the back contact protects the solar cells from moisture and heat, and they have a minimum temperature coefficient of -0.29%/°C when the power is at its peak.

3. IBC solar panels are more visually appealing.
Aesthetics and performance go hand in hand with IBC technology. IBC panels, unlike PERC panels, have no frontal metal contacts for an elegant and sleek appearance.IBC panels can be easily customised to fit a variety of shapes and sizes, giving users confidence that their solar energy choices will not jeopardise the visual integrity of their structure.

4. IBC solar panels have a broader range of applications.
IBC technology combines aesthetics and performance in a seamless manner. IBC panels, unlike PERC panels, have no frontal metal contacts, giving them an elegant and smooth appearance. Users can go solar with confidence without compromising the aesthetic integrity of their project, making them ideal for PV building integration scenarios.

Both IBC and TOPCon technologies are cutting-edge developments in the solar industry that improve the efficiency and performance of solar panels. They do, however, have distinct characteristics and considerations.

1. IBC solar panels are more efficient at generating electricity: Data shows that IBC panels are sometimes more efficient than TOPCon panels, as IBC has a theoretical conversion efficiency limit of 29.1%, which is higher than TOPCon's 28.7%. Both technologies are extremely efficient.

2. Manufacturing Complexity: Because TOPCon technology is an upgrade of PERC technology, it does not add much to the final cost of the product; however, as a manufacturer with 15 years of solar panel production strength, Maysun Solar is able to offer competitive pricing for IBC panels, further enhancing IBC solar panels' market competitiveness.

3. IBC solar cell technology is more commercially viable: Currently, both technologies are commercially viable based on a number of factors such as manufacturing costs, scalability, and consumer demand. However, because IBCs are single-sided, they can be combined with TOPCon, HJT, Calcium Titanite, and other cell technologies to create TBC, HBC, and PSC IBC technologies, all of which have higher conversion efficiencies.

4. IBC solar panels are more durable and reliable: Compared to TOPCon solar panels, IBC solar panels are more durable and reliable, with IBC cells degrading by 1.5% in the first year and an average of 0.4% per year thereafter over a 25-year warranty period.

Mayun Solar, a pioneer in renewable energy, has launched its latest breakthrough range of IBCs in a variety of colours, including all black, black frame, and silver frame, with power ranging from 410W-600W. The modules are cleverly designed and have a conversion efficiency of up to 22.8%, making them an excellent choice for both residential and commercial rooftops!
