Are you impressed with our product portfolio? You'll find your ideal solar system at Q.CELLS!
Your way to solar electricity
There's nothing magic about operating your own photovoltaic facility. And you will be a energy producer in no time at all!
The new Q.CELLS generation
- Anti PID Technology (APT)1: No power loss caused by potential-induced degradation.
- Traceable Quality (Tra.QTM): First traceable, forgery proof solar cell on the market.
- Reduced serial resistance due to new cell concept with 86 fingers and 3-busbar layout: Increased power on module level.
- Positive sorting + 0.2 / -0 %: Extra output.
- Backside with 3 x 6 busbar pads: The new standard for future efficiency efficiency boosts.
- Hot Spot Protect (HSP): Performance protection and improved fire safety.
- Full-square format: Additional 3% power output compared to pseudo-square mono cells.
- Homogenous black design: The perfect solution for highly esthetical modules.
- 2.5% safety margin included for the intital light-induced degradation of mono cells: yield security from the beginning.
- Comprehensive support for further processing and module certification: The best solution for your module.
1 APT test conditions: Cells at -600 V against frame, wet module surface, 25 °C, 300 h

The new benchmark
Q6LMXP3 is a powerful mono-crystalline standard solar cell in an attractive design. And that's not all: It is the first PID1 and hotspot-free solar module on the market anywhere in the world. The full-square format and security buffer against light-induced degradation make the Q6LMXP3 the perfect solution for all applications that require peak performance. With its homogenous black look, the Q6LMXP3 is also perfectly suited for aesthetically demanding applications. The full-square format enables up to 4.2 Wp of cell performance. This corresponds to a 3% performance boost over mono-crystalline standard cells with the same efficiency ratios. The Q6LMXP3 manages a ratio of 18.8%, making it the top performing mono-crystalline solar cell on the market.
Light is energy
How a solar cell works
Light acts as both a wave and a particle. Einstein described light as a "conglomeration of projectiles". If these projectiles – the photons – have sufficient energy and hit a free electron in a conductor or semiconductor, that electron is set into motion. Electricity begins to flow. It is drawn off the surface of the solar cell through silver contacts. Several cells are connected via contacts to form a module. The electricity generated in this way can be used directly or fed into the power grid.
From wafers to cells
How solar cells are produced
The wafers initially pass through several chemical baths to remove microscopic damage from their surfaces. A negative-conducting film is then applied onto their surfaces. Afterwards an additional film is applied to allow more light to penetrate the wafers. Front and back contacts are then printed on the wafers and burnt in using a furnace. The finished cells are then meticulously checked and classified based on efficiency, electrical and visual characteristics.

The most reliable and most secure solar cells on the market – your success energized by Q.CELLS
Q.CELLS is committed to the development of new, reliable photovoltaic products. Over 200 ambitious scientists and engineers at our research centre in Solar Valley work at increasing our cells' yield and quality. Q.CELLS solar cells are subject to extreme test conditions and attain top efficiencies.
Our philosophy lies in the sustainable partnership. We satisfy our customers' individual needs through expert guidance and short response times. After the delivery of our solar cells we support our partners in optimum further processing. Together with our customers we are pushing photovoltaics ahead.
The professional solar cell manufacturing of Q.CELLS creates innovative and high-quality products
Our customers expect high-quality solar cells with exactly defined product properties. In order to meet these expectations Q.CELLSs is permanently working on optimum cell solutions for each respective requirement. Our innovations have set many standards in the PV sector - e.g. the extended 6-inch cell format (156 mm x 156 mm), the acid-etched/textured multicrystalline solar cell or full-square monocrystalline solar cell. We constantly set ourselves new challenges to fulfil our customers' expectations for reliable solar cells with secure yields.
The development and optimisation of solar cells to the point where they are production-ready is a process that takes place under the most comprehensive quality requirements. Our partners can be sure that Q.CELLS’ products are among the PV sector’s leaders in terms of production quality and efficiencies.
