Was bedeutet Heterojunction? Die HJT-Solarzelle ist eine Kombination aus einem kristallinen Silizium-Wafer und einer Dünnschichtzelle aus amorphem Silizium. Während in normalen Solarzellen das gleiche Halbleitermaterial unterschiedlich dotiert wird, um einen pn-Übergang zu erzeugen, entsteht dieser bei der HJT-Solarzelle zwischen zwei unterschiedlichen

The quality of welding strip will directly affect the current collection efficiency of photovoltaic module, so it has a great impact on the power of photovoltaic module. The so-called photovoltaic welding strip is to coat binary or ternary low-melting alloy on the surface of copper strip with given specification.
The shading area of the photovoltaic welding strip is reduced by reducing the width of the main grid line and the PV welding strip, and the total amount of light received by the solar cell is increased. However, the contact resistance of the whole PV assembly is too large, which increases the electrical loss of the photovoltaic module.
