6 FAQs about [Price of photovoltaic panel waste silicon powder]

How much does it cost to recycle silicon PV panels?

8.1. Technical challenges Cost of Recycling: The primary challenge is the high cost of recycling silicon PV panels, estimated to be around $600–1000 per ton (excluding material revenue) (Heath et al., 2020). Lowering this cost to $300–400 per ton is essential for making the recycling process economically viable (Deng et al., 2019).

What is the economic value of crystalline silicon PV panels?

The economic value of the valuable metals is $13.62/m 2, resulting in a profit of $1.19 per recycling of 1 m 2 of crystalline silicon PV panels. The breakdown of total revenue generated after selling the recovered valuable materials is as follows: 46% (aluminium), 25% (silver), 15% (glass), 11% (silicon), and 3% (copper).

What is the recycling process for silicon-based PV panels?

In this review article, the complete recycling process is systematically summarized into two main sections: disassembly and delamination treatment for silicon-based PV panels, involving physical, thermal, and chemical treatment, and the retrieval of valuable metals (silicon, silver, copper, tin, etc.).

How much e-waste will be produced from silicon PV panels in 2050?

Projections suggest that e-waste from silicon PV panels may reach 60 to 78 million tonnes by 2050 (Song et al., 2023; Guinée, 2002), with environmental and health risks due to the presence of aluminum, silicon, lead, cadmium, and tin (Tan et al., 2022; Jain et al., 2022).

What is crystalline silicon based PV industry?

Considering the wastes of silicon (Si) resources, silicon-based PV industry could be the biggest one, particularly crystalline silicon (c-Si) PV module (0.67 kg Si/module), which occupies over 93% of the total production. Among various parts of the PV module, PV cell is the most important part, which uses high-quality silicon wafers.

Can discarded silicon-based photovoltaic panels be recycled?

The increasing scrapped Si-based photovoltaic (PV) panels has become an urgent problem, and their disposal is essential for resources utilization and environment issues. This paper proposes a comprehensive process for recycling of discarded silicon-based PV panels economically, environmentally, and efficiently.
