Panel trends have a way of quickly becoming mainstream. IHS Markit predicted that passivated emitter rear cells (PERC) technology would go from a blip in the market in 2014 to mainstream by 2020—a prediction confirmed by anyone looking at panel models released this year. PERC is here to stay.
The next technology on that mainstream path is half-cell designs. The ninth edition of the International Technology Roadmap for Photovoltaic (ITRPV) predicts the market share of half cells will grow from 5% in 2018 to nearly 40% in 2028.
Half-cell modules have solar cells that are cut in half, which improves the module’s performance and durability. Traditional 60- and 72-cell panels will have 120 and 144 half-cut cells, respectively. When solar cells are halved, their current is also halved, so resistive losses are lowered and the cells can produce a little more power. Smaller cells experience reduced mechanical stresses, so there is a decreased opportunity for cracking. Half-cell modules have higher output ratings and are more reliable than traditional panels.
“When considering a solar installation, the idea of ‘more’ is at the forefront—produce more energy, save (or earn) more money and do more good for the environment,” said Cemil Seber, VP of global marketing and product management for module manufacturer REC. “In the case of rooftops where there is a limited amount of space available, using solar panels with half-cut cell technology can help.”
REC is a half-cell pioneer, first introducing the design in 2014. The company’s TwinPeak half-cell module series effectively turns each panel into two twin panels. Since the cells are smaller, inter-cell spacing doesn’t have to be as wide and they can be placed closer together. This allows REC to separate the panel into two. Independent upper and lower module halves lead to improved shading response. If the bottom half of a module is shaded, the top half will still perform.
REC has pushed the boundaries with half-cell designs in polycrystalline modules. REC’s half-cell PERC polycrystalline modules have reached 300 W, and they can compete with full-cell modules in the more efficient monocrystalline class. The company has been so impressed by the advantages of half-cells, it is transitioning all its manufacturing lines to the new technology.
“Since 2014, REC has been continuously transferring its production lines to half-cut cell technology,” Seber said. “Today, all but one of our module production lines in Singapore have been equipped for half-cut cell technology.”
During the 2018 tradeshow swing, REC released its new N-Peak series of modules, the company’s first stab at monocrystalline half-cells for even higher efficiency and output—up to 330 W in a traditional 60-cell footprint.
Other manufacturers have also started half-cell designs in the monocrystalline class. LONGi Solar recently exceeded 360 W in testing with its 120-cell half-cut monocrystalline PERC module. Hanwha Q CELLS received the Intersolar Award 2018 Photovoltaics category for its Q.PEAK DUO-G5 solar module—a 120-half-cell, six-busbar monocrystalline module. The Hanwha module uses round wires instead of flat ribbons for busbars to reduce shading on the cells. Hanwha also has half-cut designs for the 72-cell market, although in polycrystalline. Its Q. PLUS DUO L-G5.2 is a polycrystalline half-cell module with a maximum output of 370 W.
Since half-cell designs are the hottest trend right now, a manufacturer just has to update a few things on its lines to keep up. The two challenges with switching full-cell manufacturing to half-cell designs is the cell cutting and the stringing process. Since half-cells are usually PERC cells to begin with, the cell itself is quite fragile. Laser-cutting the cell down the middle without cracking it is a delicate process. Half-cells often use four or more busbars. Stringing these very narrow connection strips across a smaller footprint requires the use of precise equipment. Junction boxes are also different on half-cell modules. Most brands use multiple, smaller junction boxes so each module half can function as its own. Otherwise, half-cell module assembly is like full-cell production.
Since half-cell modules produce more power and are more efficient and reliable than their full-cell counterparts, their use can lead to time and money savings for the installer.
“By delivering more power per square meter, fewer panels are required to generate the same power,” Seber said. “This means quicker installation times and the need for fewer components such as clamps and racks—all of which reduces the overall costs.”
