Silicon-based passivating contacts: The TOPCon route

2023
Passivating contacts based on poly-Si/SiOx structures also known as TOPCon (tunnel oxide passivated contacts) have a great potential to improve the efficiency of crystalline silicon solar cells, resulting in more than 26% and 24% for laboratory and industrial cells, respectively.

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.

Degradation Mechanism of TOPCon Solar Cells in an Ambient Acid Environment

ACS Applied Materials & 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). However, acids generated from encapsulant hydrolysis under damp-heat (DH) conditions significantly impair the reliability of TOPCon solar ...

Unveiling the Photovoltaic Performance and Thermal Stability of n‐TOPCon, p‐TOPCon, and TOPCoRE Solar Cells Based on 110 μm Wafers

Energy Technology
The choice of the best possible TOPCon solar cell architecture in terms of photovoltaic performance, thermal stability, and bifaciality has been one of the most fundamental issues to be addressed. Accordingly, a theoretical approach with the help of Automat FOR Simulation of HETero‐structure simulation software has been adopted to conduct a detailed ...
