How solar panels work
Light is basically just lots of particles called photons. The solar cell absorbs these photons. When they hit the solar cell, they knock another particle called an electron out of the solar cell, leaving a hole behind. This is the photovoltaic effect. I’ll explain in detail how it works later in the article.
However, the Xi’an-based solar panel maker disputed the 30% figure and said job reductions would amount to around 5% of its workforce. (That’s still thousands of jobs.)
