A solar cell is an electrical component that transforms sunlight into electricity through the photovoltaic effect. This process occurs thanks to the use of semiconductor materials, which can have different compositions and technologies to optimize energy conversion.

The manufacturing of these cells is a highly technological process that is essential for the advancement of solar energy. Directly from the DAH Solar factory in China, it is possible to follow each stage of this transformation, from the initial inspection of the wafers to the advanced doping and texturing procedures, which ensure greater efficiency in the conversion of sunlight into electricity.

O Canal Solar was present at the company's factory and closely monitored the entire process. Check it out:

An answer

  1. Poor explanation: what is a wafer, what is it made of? what is doping? how are the mini cells separated on the wafer and how are they connected to each other?
