LCA is conducted on the multi-crystalline silicon photovoltaic systems in China. Multi-Si production is the most contributor to the energy demand and environmental impacts. Compared to other power generation systems in China, PV system is more environmentally friendly. Areas with higher solar radiation are more suitable for installing PV systems.
In response, China issued AD duties up to 57% on solar-grade polysilicon imports from the USA and EU in 2013–2014. These external shocks affected the Chinese PV industry from both sides. First, Chinese cell manufacturers lost large shares of the international demand, as their prices became less competitive in an already shrinking market.
China's PV cell production corresponds to the global market by being mostly focused on c-Si technology. The production of c-Si PV cells goes through three main groups of purification and fabrication processes.
The inventory data, including the material consumption and environmental emissions involved in the production of solar-grade silicon, wafers, ingots, cells, and modules, were mainly collected from companies that represent the current domain multi-Si PV technologies in China.
China has a prominent role in the literature on photovoltaics (PV) technologies in developing countries, as it experienced dramatic production growth during a very short period. In 2003, China's share in PV global production was less than 1%.
It defines six main patent groups for the PV system: (i) solar cells, (ii) solar panels, (iii) electronics, (iv) monitoring and testing, (v) energy storage, and (vi) portable devices for lighting, heating and cooling purposes. These groups each consist of subcategories with more details on specific technologies.
