Q-Cells solar cells undergo an automated manufacturing process starting with the incoming inspection of the silicon wafers through to final inspection and testing. This enables us to produce solar cells with efficiencies of over 17 %. Our production processes are constantly monitored and optimized. Every cell is subject to the most stringent quality inspection procedures and undergoes unique testing measures. With our inspection and testing criteria, we have set global standards.
| Pos. | Test criteria | Aim | Customer Benefit |
|---|---|---|---|
 | Current testing at 0.5 V / 25 °C; 1000 W/m², AM 1.5 | Avoiding mismatch of modules under standardized default conditions | Higher module energy output |
 | Current testing at 0.5 V / 25 °C; 500 W/m², AM 1.5 | Optimizing cell output on module level for central European weather conditions | Increased annual energy yield under central European operating conditions |
 | Shunt resistance testing | Optimizing cell output on module level in low-light | Increased annual energy yield under central European operating conditions |
 | Reverse current analysis | Avoiding hotspot effects on module level | Safety and durability for reliable energy yield |
 | Infrared analysis | Avoiding hotspot effects on module level | Safety and durability for reliable energy yield |
 | Very narrow efficiency class tolerances (± 0.2 % absolute) | Significantly reducing module mismatch and stabilizing Gaussian distribution of modules | Higher module output, reproducible production processes |
 | Visual inspection of properties with sorting into two predefined color categories (light / dark) | Improving the appearance of modules | Improved homogeneity and visual aesthetics for end users |
 | Mechanical stability | Avoiding surface damage and bending; complying with specified cell thickness tolerances | Minimizing the risk of breakage during further processing, improved appearance of the solar cell front |
