AI Technical Summary
The thickness of existing graphite boats limits the number of boats that can be stacked in photovoltaic PECVD equipment, resulting in insufficient production capacity.
The boats are made of carbon-carbon composite material and multiple boats are fixed and connected to electrodes through a connecting assembly of ceramic rods, ceramic tubes and locking nuts. The thickness is 1.0-1.5mm, which increases the number of boats.
Without compromising the strength of the solar panels, the thickness of the solar panels was reduced, the number of solar panels was increased, and the production capacity of photovoltaic equipment was improved.
