Poly-Si (n) Removal for TOPCon Solar Cells

2023
This work gives results on wet chemical parasitical polysilicon removal for tunnel oxide passivated contact (TOPCon) n-type silicon solar cells. The poly-Si removal is important to fabricate TOPCon cells with low reverse bias junction leakage current density (jrev,2).

Comparison of Topcon Optical Coherence Tomography and Ultrasound Pachymetry

Optometry and Vision Science, 2012
To establish within-rater repeatability and minimum measurements required for reliable assessment of central corneal thickness (CCT) using Topcon three-dimensional OCT-2000 (Topcon Medical Systems, Oakland, NJ) Fourier-domain optical coherence tomography (FD-OCT) and to test agreement against ultrasound pachymetry (USP).Twenty participants underwent ...

Optimization of TOPCon Structured Solar Cell Using AFORS-HET

Transactions on Electrical and Electronic Materials, 2020
The tunnel oxide passivated contact (TOPCon) structured solar cell, improved version of first-generation PERT solar cell, delivers the highest power conversion efficiency, and is the most commercially available. The first-generation solar cell still suffers from recombination losses, which strongly impacts the conversion efficiency of the cell.

Industrial TOPCon Solar Cells realized by a PECVD Tube Process

2020
These days low-pressure chemical vapor deposition (LPCVD) is commonly used by the photovoltaic industry to deposit Si layers for tunnel oxide passivated contact (TOPCon). This work summarizes the development of an alternative TOPCon deposition process using a tube plasma-enhanced chemical vapor deposition (PECVD) tool.

Accuracy of Topcon CM-1000 Videokeratoscope on Spherical Test Surfaces

Journal of Refractive Surgery, 1997
ABSTRACT BACKGROUND: Many videokeratoscopes use mathematical formulas to calculate corneal radii; calculations depend on slope, curvature, coordinate position, or focal properties of the surface. Accuracy of each type of videokeratoscope must be evaluated.
