Photovoltaic Quartz Boats

Semicorex photovoltatic quartz boats are indispensable consumables that facilitate the the production of monocrystalline and polycrystalline silicon wafers in photovoltatic photovoltaic manufacturing processes, such as diffusion, oxidation, and annealing. They are specially designed for the high-temperature processing under an atmosphere of high-purity nitrogen, oxygen or other inert gases to dope silicon wafers and form PN junctions on the silicon wafers, thereby enhancing the conversion efficiency and performance of solar cells.

The advantages of Semicorex photovoltatic quartz boats

1. Stable load bearing

Benefiting from the outstanding high-temperature resistance and extremely low coefficient of thermal expansion of high-purity fused quartz, Semicorex photovoltatic quartz boats can withstand long-term high-temperature environments of 1100-1200 degrees Celsius. Even when they experienced the drastic temperature fluctuations over short periods, they can still keep their structural integrity without any damage. This performance allows Semicorex photovoltatic quartz boats to continuously provide stable support for solar-grade silicon wafers under challenging high-temperature operational conditions.

2. Precision positioning

In order to ensure that process gases act uniformly on the surfaces of silicon wafers during operation, Semicorex adopts precision machining technology to guarantee consistent spacing between each slot in its photovoltaic quartz boats. This equidistant slot design secures the silicon wafers in fixed positions to be uniformly heated during high-temperature processes, which effectively improves the consistency and stability of solar cell performance.

3. contamination prevention

Semicorex photovoltatic quartz boats are manufactured from high-purity fused quartz with low impurity content. This premium material gives Semicorex photovoltatic quartz boats superior chemical stability, which graetly prevents them from reacting with silicon wafers or process gases, reduce impurity introduction and maintain the high cleanliness of the production environment. This feature has a significant impact on improving the production yield of solar-grade silicon wafers.
