HJT

The long read: All that glitters is HJT

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 long read: Carriers key for quality cell surfaces

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 long read: Considering the competitive landscape for HJT

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.

The long read: The glue that binds HJT

The push towards higher-efficiency technologies drives innovation right across the supply chain. Long proven in the electronics industry, an electrically conductive adhesive (ECA) is now being deployed in heterojunction production, facilitated by new equipment.
