17.5% p-Type Silicon Heterojunction Solar Cells with HWCVD a-Si:H as the Emitter and Back Contact
Thin hydrogenated amorphous silicon (a-Si:H) layers deposited by hot-wire chemical vapor deposition (HWCVD) are used as both emitters and back contacts in silicon heterojunction solar cells. LowExpand

Investigation into the effect of wheel groove depth and width on grinding performance in creep-feed grinding
This work presents an investigation into the effects of different groove depths and groove widths on grinding performance in creep-feed grinding using grinding wheels with spiral-shapedExpand
High-Efficiency p-Type Silicon Heterojunction Solar Cells
Evaluating print performance of Sn‐Ag‐Cu lead‐free solder pastes used in electronics assembly process
Solder paste is the most widely used interconnection material in the electronic assembly process for attaching electronic components/devices directly onto the surface of printed circuit boards, usingExpand
17.8%-efficient Amorphous Silicon Heterojunction Solar Cells on p -type Silicon Wafers
We have achieved an independently-confirmed 17.8% conversion efficiency in a 1-cm 2 , p-type, float-zone silicon (FZ-Si) based heterojunction solar cell. Both the front emitter and back contact areExpand
