New method for life cycle assessment of PV technologies

Share

Scientists at Australia’s Charles Darwin University have conducted a cradle-to-grave life cycle assessment (LCA) of the four most widely used PV technologies; monocrystalline silicon (mono-Si), multi-crystalline silicon (multi-Si), amorphous silicon (a-Si) and cadmium telluride (CdTe).

The LCA was based on the ‘ReCiPe’ life cycle impact assessment method first developed by academics in 2008. This method utilizes a total of 21 indicators to evaluate the environmental impacts of a technology or product on three higher levels: human health, biodiversity and resource scarcity. The indicators focus on single environmental problems, such as climate change.
