Introduced modules with loss-minimizing half-cut cell technology.2012

Building upon almost a centur y of manufacturingexperience since our founding in 1921, we k now how to make our products last.Rest assured that we w ill be there for you in the long term.

Protective LayerProtects against the elements

Highly Re�ective LayerIncreases module output

Moisture BarrierPrevents water intrusion

By reducing the area of each cell and connecting them in a parallel formation, the amount of electrical current carried by each busbar is reduced by half.

approximately 2.5%.

Cells are cut with a special process using a high-precision laser to maintain the integrity of the cell.

Half-cut Cell

Anti-re�ective coating Lightly doped region(low carrier charge recombination loss)

Heavily doped region(greater conductivity)

Silver electrode

Electrical losses = Current 2 × Resistance

By using half-cut cells, the electrical current ( i ) �owing in each busbar is halved. Therefore, the amount of internal loss in a half-cut module is 1/4 of a full sized cell module.

inter-cell connections as another initiative contributing to environmental protection.

Two modules as seen from a thermographic camera. �e module on the le� has highly resistant cells mi xed in, generating spots of heat relative to the rest of the module. �e module on the right is a Mitsubishi Electric module, w ith uniform performance.

Ever y cell we produce is measured for electrical characteristics and undergoes a ver y strict selection process before being assembled into a module. �is is to minimize performance degradation due to cell variation.

Advanced Production Techniques

Mitsubishi Electric has developed numerous advanced techniques in production.For example, we have developed a method during the p/n junction forming process to move impurities in the sil icon wafer into deeper areas. By leading the impurities away from the surface, generated electricity is less l ikely to recombine w ith them (recombination loss) and overall output is improved.

Tested in Extreme Conditions

Our modules have been designed to w ithstand harsh environmental conditions, such as in areas w ith high snow fall . �e high structural strength of the modules has passed the IEC 61215 static loading test at 5400Pa and the thermal cycling test of -40˚C to 85˚C.
