Design of Dismantling and Recycling Equipment for Junction Boxes of Waste Crystal Silicon Photovoltaic Modules

The dismantling and recycling of junction boxes,which is an important part of the photovoltaic module recycling process,was tested and designed scientifically.The equipment framework was built by three-dimensional simulation,and then the design of dismantling and recycling equipment for junction boxes of waste crystal silicon photovoltaic modules was completed through the experimental test and data analysis.The experimental results show that the initial idea of the dismantling scheme is correct,and the structure is feasible.However,some problems were not considered.This study provides reliable data support for the subsequent equipment development and ensures the smooth development of the subsequent design work.

Status quo on recycling of waste crystalline silicon for photovoltaic modules and its implications for China's photovoltaic industry

As a clean and efficient renewable energy source,solar energy has been rapidly applied worldwide.The growth rate of China's installed capacity ranks first in the world.However,the life span of photovoltaic(PV)modules is 25 to 30 years,and the rapid development of installed capacity indicates that a large number of PV modules will be decommissioned in the future.Therefore,the ongoing treatment of the scrapped PV waste cells in the near future requires urgent plans and countermeasures.Proper recycling and disposal of decommissioned PV modules is a practical requirement for the sustainable development of the country and industry.Crystalline silicon(c-Si)solar cells currently occupy 85%-90%of the market share,and some scholars have begun to seek the utilization pathways of the waste Si in and outside the PV industry.In this paper,the research status of the separation and recycling process of crystalline Si PV modules is reviewed,and the recycling ways of crystalline silicon are particularly focused on.In addition,the current bottlenecks in the PV recycling industry in China are analyzed and some suggestions on the sustainable development of the PV industry are proposed.

Photovoltaic waste management in sub-Saharan Africa:current practices in Burkina Faso

Sub-Saharan Africa is witnessing a proliferation of photovoltaic(PV)waste due to the increasing number of solar PV power plants.PV waste(panels,batteries,electrical cables,mounting structures,and inverters)consists of elements such as mercury,cadmium,chromium,lead,copper,aluminum,fluorinated compounds,and plastics that are toxic to human health and the environment if a proper management system is not available.Although many studies worldwide have focused on PV waste management,very few have been conducted in sub-Saharan Africa.This study aims to investigate the current PV waste management system in Burkina Faso,determine stakeholder profiles,and propose strategies to enhance the existing system.Documentary research,interviews,questionnaires,and field visits were used in the methodology.The survey showed that young people,mainly under 30 years of age and with a primary education,dominate(70%)in terms of PV waste collection and repair activities,while the more technical recycling and export activities are carried out mainly(88%)by stakeholders older than 40 years and with a secondary education(60%).Among the older stakeholders,100%are aware of the hazardous nature of PV waste,whereas 36%are young people.From an environmental perspective,the main source of contamination observed is the release of lead-rich sulfuric acids into water and soil during the collection and repair phases.During the recycling of batteries and electrical cables,toxic fumes are emitted into the air,and recycling residues rich in toxic substances are landfilled.To reduce risks to human health and the environment when managing PV waste,the introduction of legislation,the multiplication of collection points and appropriate infrastructures,the training and awareness-raising of stakeholders,and the extended responsibility of manufacturers are recommended.Studies on the economic feasibility of setting up formal management structures are needed to complete this work.
