Q.ANTUM Technology
The evolution of Q.ANTUM technology never stops
As a pioneer in the solar industry, Qcells has experts in every field of solar engineering and manufacturing. Qcells’ proprietary Q.ANTUM Technology has been a game-changer in terms of raising standards in module performance and efficiency throughout the solar industry.
The evolution of cell technology starts on p-type cells from ‘Q.ANTUM’, ‘Q.ANTUM DUO’ to ‘Q.ANTUM DUO Z,’ and all-new premium n-type cell technology, ‘Q.ANTUM NEO’ will be introduced in 2022.

Q.ANTUM
Industry’s first commercialized advanced PERC technology
Power Output
compared to standard BSF cell (PERT technology)
Q.ANTUM is the most mature PERC (Passivated Emitter and Rear Cell) technology, and Qcells was the first solar company to commercialize the technology. With the birth of Q.ANTUM, PERC technology could finally be rolled out into mainstream use across fields and rooftops globally. Q.ANTUM has been constantly evolving and providing our customers with world-leading quality.
Advanced PERC Technology
Produce the same yield with fewer modules
PERC, by all means, allows for the passivation of the solar cell´s rear side, which involves installing a reflective layer, designed to capture previously unused sunlight back into the cell where it can be converted into solar electricity.
Qcells’ Power Reflector
A Special Nano Coating on the rear surface of the solar cell
Rays of sunlight that would otherwise go to waste are mirrored by the Power Reflector back through the cell to generate more electricity. Laser-fired contacts complement the nano coating to enhance the module’s electrical properties, increasing its efficiency considerably.

Q.ANTUM DUO
Half-cell on Q.ANTUM Technology with Multi Busbars and Wire Interconnection
Power Output
compared to standard PERC technology solar module
Based on our original Q.ANTUM Technology and Half-cell technology with multi busbars and wiring interconnection deliver not only superior performance, but also overwhelmingly beautiful aesthetics. Q.ANTUM DUO Technology reduces both electrical and optical losses by halving the current passing through each cell while making use of incident light more effectively.
Multi Busbars Technology
Less resistance and better capture of excited electrons
Reduced distance in between the busbars and additional paths for electric current results in 2% power increase. More paths can be created with the shorter distance leads lower congestion, which in turn reduces resistive losses.

Half-cell Technology
Greater output by halving the current
Halving the cell halves the current. When combined with a module layout which reduces the distance traveled by the electric current, the result is a 3% increase in power. Two half cells with 12 busbars have the same or even greater output as a full cell with 24 busbars.
Wire Interconnection
Reduced shading losses with round wires
Utilizing wires instead of flat ribbons reduces both the width and the effective shading width decreasing shading by 75% and increasing the power by 2.5%. The light reflected from the round shape of the wires improves the light capturing effect of the module.

Q.ANTUM DUO Technology
Q.ANTUM DUO Z
Qcells solar modules with Q.ANTUM DUO Z Technology not only deliver impressive performance in real-world conditions, but also offer first-class performance guarantees of 98% in the first year and a full 86% after 25 years. The Q.ANTUM DUO Z Technology combines our Q.ANTUM Cell Technology with the innovative Half-cell technology with multi busbars and zero-gap cell interconnection ensure higher power generation not only in the laboratory but also in everyday operation.
The Q.ANTUM DUO Z Effect
Higher cell density higher performance
We have bundled our Qcells know-how and developed a brand new cell interconnection that enables us to minimize the gaps between Q.ANTUM solar cells. The non-existent spaces between the individual cell rows ensure a higher cell density.

Efficient Use of Space
More yield with less solar modules
Fewer gaps allow more solar cells in the module, which in turn generate more electricity and increase the efficiency by 4%.

Q.ANTUM NEO
The innovative N-type technology of Qcells
Power Output
compared to standard PERC technology solar module
Q.ANTUM has been constantly evolved on p-type cells, which are proved to be more resistant to space radiation and degradation. Now, we are expanding our technical expertise into n-type cells that are more efficient, and proud to introduce Q.ANTUM NEO, the innovative n-type technology of Qcells.
Q.ANTUM NEO Cells
N-type
Within Q.ANTUM NEO solar cells, passivation layer and electrical interconnection functionality are integrated in the NEO Power Transmitter layer. This allows full area passivation and contact at the same time, thus overcoming the PERC limitations.
Q.ANTUM NEO Cells (N-type)
Standard Cells
P-type, PERC
Standard PERC solar cells use a passivation layer with small holes for electrical interconnection of the cell rear side. Passivation is reduced in the contact area which limits the maximum efficiency.

Quality Assurance
Qcells’ four-level quality program guarantees solar module’s long lifespan
The Four Quality Levels
Level1
Yield Security
Cell level long-term performance reliability
Qcells Yield Security includes Anti PID Technology, Anti LeTID Technology, and Hot-Spot Protect technology protects the solar cells and modules from various degradation effects and hot spots.
Anti PID Technology
Potential Induced Degradation can lead a significant power loss on both p-type and n-type cells, so the APT effectively protects the solar cells and secures high energy yield in the long-term.
PID
Anti LeTID
LeTID
Anti LeTID Technology
Light and Elevated Temperature Induced Degradation (LeTID) effect can significantly damage the power of solar cells on both p-type and n-type cells. Qcells is the first company to observe LeTID effects and come up with a solution to suppress LeTID in 2015.
Hot-spot Protect
One hot-spot can lead to continual yield loss, and in the worst case scenario, the module can catch fire. In order to prevent hot-spots in cells, we inspect the solar cells in various ways, such as infrared camera scanning since 2008.
Hot-spot Protect
Level2
Initial Certification
Guaranteed electrical safety and construction of modules
Qcells’ modules get initial certifications from external institutes, such as IEC and UL.
Level3
Quality Controlled PV (QCPV)
TÜV seal for the most reliable
Qcells is the first solar module manufacturer in the industry to pass TÜV Rheinland’s new Quality Controlled PV (QCPV) certification, the most thorough testing program in the industry. Developed by TÜV Rheinland, QCPV is not only the most extensive and stringent test program to date, but is also the only certification in the entire industry to involve independent and random onsite testing by external experts, as well as regular material and supplier test.
Uncompromising Testing Standards
Our solar modules pass over 40 individual tests. We are raising the bar of quality standard within solar industry, applying up to 3 times stricter standard than global standards.
Onsite Production Monitoring
QCPV is the only testing program in that an independent expert from TÜV Rheinland continuously monitors the quality and monitoring measures at Qcells sites, in order to be able to guarantee product stability.
Component & Materials Audits
To detect any quality fluctuations at an early stage, thereby keeping them out of production, we even check particularly critical components and materials, using special analysis methods.
