HJT

India is seeing massive investments in PV manufacturing, with manufacturers from Western countries, led by the United States, eager to get in on the act. Chinese companies have yet to make the same call, however.

Reliance Industries says that production will begin at its 10 GW factory for solar cells and modules by 2024. It plans to double the facility’s capacity to 20 GW by 2026 and is aiming for 50 GWh of annual cell-to-pack battery capacity by 2027.

Trina Solar said Germany’s TÜV Nord has confirmed the efficiency rating of its latest solar cell.

An international research group has reconstructed the trajectory of p-type wafers in the heterojunction solar cell segment and has identified the lack of knowledge about boron-oxygen related light-induced degradation (BO-LID) as the main cause for the limited adoption of these wafers and the success of their n-type counterparts. According to the scientists, however, there is still big room for improvement for p-type technologies in heterojunction cells.

French solar energy institute INES has developed new PV modules with thermoplastics and natural fibers sourced in Europe, such as flax and basalt. The scientists aim to reduce the environmental footprint and weight of solar panels, while improving recycling.

Against all odds, China’s gross domestic product grew by 8.1% in 2021, up 5.8% year on year. Electricity consumption grew by 10.3%, up 7.2%. Taking this into account, it’s no surprise that China’s PV industry also reached new heights. Frank Haugwitz, the founder of the Asia Europe Clean Energy (Solar) Advisory (AECEA), takes a closer look at what is still by far the world’s largest PV market.

HJT technology could fill an innovation gap in the residential and commercial rooftop PV market, and boost U.S. solar leadership through domestic manufacturing of cells and modules.

The devil is in the details, as they say, and when it comes to the next generation of mass-produced, high-efficiency PV cells, silver costs may be devilishly hard to reduce. Making things worse, prices for the precious metal are now heading in the wrong direction.

The path to lower solar LCOE can be painful; just ask a PV manufacturer. However, ever-larger crystalline wafers may cause more pain than they are worth, argues Gerry Knoch, the managing director of wet bench provider exateq. For high efficiency, eliminating cross contamination in wet processes is vital and can be achieved – with carriers playing an important role.

The benefits of heterojunction technology are well known. But as the first modules come onto the market from REC Group’s new HJT lines, the competitive landscape is crowded, but not without opportunity.
