n-type wafers

Differences in wafer and module specifications, which have bedevilled solar developers in recent years, could now be narrowing.

Seraphim is offering four versions of its new SIV N-TOPCon modules, with power outputs between 565 W and 580 W. The power conversion efficiency ranges from 21.87% and 22.45%.The Chinese manufacturer said the panels can be used for distributed-generation PV projects and ground-mounted power stations.

Fraunhofer ISE scientists have identified the best metallization pastes to help reduce contact resistivity and contact recombination in p-type TOPCon solar cells. They applied a silicon nitride layer through plasma-enhanced chemical vapor deposition onto both sides of a cell.

The polysilicon manufacturer took a step back in the last quarter to take two steps forward in the next, bringing forward annual maintenance operations at its main production facility to prepare for a solar gold rush expected to start next month.
