What is a half-cut cell PV module?

In a traditional silicon cell-based PV module, the ribbons interconnecting neighboring cells can cause a significant loss of power during the current transport. Cutting solar cells in half has been proven to be an effective way to lower resistive power loss.

The half-cut cells generate half the current of a standard cell, reducing resistive losses in the interconnection of solar modules. Less resistance between the cells increases the power output of a module. Solar Power World Online has noted half-cut cells can potentially boost power output between 5 to 8 W per module, depending on the design.

With a higher power output on module that costs relatively similar, it speeds up ROI. This makes the cells a great idea for end users who want a quicker turnaround on their investment.

After conducting a series of tests of half-cut and PERC solar cells in a large-area PV module during in a controlled environment, the Institute for Solar Energy Research Hamelin broke the previous record for module efficiency and peak power output, PV-Tech reported. While they're not the only organization performing ground-breaking work on half-cut cells, the record, which was independently confirmed by TUV Rheinland, demonstrates the viability of using these modules to bring PV development to its most advanced and lowest cost yet.

Because of its performance gains, many companies have already switched to half-cut designs, which should further increase market share for these PV products.
