Solar Cell Ceramic Components are installed directly on solar-cell production equipment. Typical examples include supports for diffusion-furnace quartz boats, electrode insulation parts in PECVD systems, ceramic worktables on screen printers, and conveyor guides in firing furnaces.

Core Advantages

1500-1800°C Material Temperature Range

Maximum working temperature is 1500-1800°C depending on material. For supports and insulating parts close to diffusion or firing zones, the ceramic grade can be selected around the required process temperature while keeping the same equipment interface.

3.5-8.5 X 10^-6/°C Thermal Expansion

Thermal expansion coefficient is 3.5-8.5 x 10^-6/°C, depending on material. During repeated heating and cooling, this range helps limit dimensional movement at locating and support points so the ceramic can hold its position through thermal cycles.

350-900 MPa Flexural Strength Range

Flexural strength is 350-900 MPa depending on material. Worktables, supports, and conveyor guides can be matched to both the mechanical load and process temperature instead of using one material grade for every position.

Customization

Material

Projects can use high-purity alumina or silicon nitride.

Geometry and Equipment Interface

Customer drawings can define non-standard geometry such as mounting holes, slots, stepped sections, contact faces, and locating features.

Dimensional Accuracy

Finished dimensional accuracy can be selected within the listed ±0.02 to ±0.1 mm range to suit the component structure and fit requirement.

Quality Control

For parts used in thermal cycling, dimensions are checked again after the relevant heat-processing sequence and before shipment. The recheck is used to catch deformation or dimensional change that could create fit or loosening risk before installation.

Finished geometry is compared with the approved drawing. Mounting interfaces, support faces, guide surfaces, holes, and other process-facing features are checked according to the part's function, while visible cracks, chips, and edge damage are screened out.

The shipment receives final inspection before packing and remains linked to the production-batch record. Third-party inspection is accepted when specified, and exposed working faces are protected from contact damage in transit.
