Highly Efficient Monolithic Perovskite/TOPCon Silicon Tandem Solar Cells Enabled by “Halide Locking”

Advances in Materials
Perovskite/silicon tandem solar cells (TSCs) are promising candidates for commercialization due to their outstanding power conversion efficiencies (PCEs).

The Topcon DL-101C Digital Level

Australian Surveyor, 2000
Even though the Topcon digital levels have been on the market since 1994, very little has been reported on the working principle of these instruments and on the results achieved with them. This paper discusses the operating principle of the Topcon digital level DL-101C and explains how the staff reading and the sighting distance are derived from the ...

Degradation Mechanism of TOPCon Solar Cells in an Ambient Acid Environment.

ACS Applied Materials and Interfaces
n-Type tunnel oxide passivated contact (TOPCon) solar cells are expected to dominate the global photovoltaic market in the next decade, primarily owing to their rapidly increasing power conversion efficiency (PCE).

Range ratio of topcon radiation thermometers

SICE Annual Conference 2007, 2007
Topcon 0.65 mum and 0.9 mum radiation thermometers are used as the standard thermometers at high temperatures. These radiation thermometers employ three to five ranges to cover their whole temperature ranges. The range ratios of these thermometers influence largely on the calibration uncertainty.

Large Area TOPCon Technology Achieving 23.4% Efficiency

2018 IEEE 7th World Conference on Photovoltaic Energy Conversion (WCPEC) (A Joint Conference of 45th IEEE PVSC, 28th PVSEC & 34th EU PVSEC), 2018
We report on the development of the TOPCon technology on large area focusing on the deposition technology for the a-SiC x (n) layer and the rear side metallization. We demonstrate that kHz direct-plasma technology can be used to deposit the a-SiC x (n) layers and that concerns about ion bombardment damaging the thin SiO x are not justified.

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 ...
