Conventional fossil energy sources, like coal and oil, are a major source of carbon dioxide emission and thereby a significant driver of climate change [1].Anthropogenic climate change can be therefore mitigated by developing an energy system with an increase share of non-fossil technologies [1] such mitigation scenarios, renewable energies, like solar
Silicon material is the core raw material of photovoltaic power generation systems. Photovoltaic silicon material, also known as solar grade polycrystalline silicon (SoG Si), is the upstream raw material in the photovoltaic industry chain. It is a gray black solid with metallic luster, with high melting point (1410 ℃), high hardness, brittleness, and inactive chemical
Note that the peak of wind power generation occurs at night when PV power is close to zero. On the other hand, the highest average levels of PV production occur during periods of the day when wind power generally reaches its lowest patterns. Thus, more stable combined power is observed compared to each individual production due to the evident complementary effect between the
