A Proposed Method for Safe Disposal of Consumed Photovoltaic Modules
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 3
Abstract
The growth of domestic and large-scale applications of solar energy, especially photovoltaic (PV) cells which reaches annually up to 40 % worldwide since 2000, means that the technology has stepped out from demonstration phase to large-scale deployment. Several countries have started to exploit this huge potential as part of their future energy supply. Photovoltaic cells are manufactured from various semiconductors; materials that are moderately good conductors for electricity but harmful to the environment. End-of-life disposal of PV modules can be an environmental issue. However, due to the long lifespan of PV modules (25 to 30 years), currently most PV modules have not reached the disposal stage. As a result, there is very little experience and knowledge with the disposal and/or recycling techniques of PV modules. This paper proposes a method for safe disposal of solar panels after the end of their life by burying the PV cells into concrete blocks that may be used in different civil applications. Two types of PV cells (mono-crystalline & multi-crystalline) are selected to be mixed with concrete components to investigate their effect on properties of concrete. The experimental results showed that the PV cells have an effect on the concrete properties. Reduction of concrete compressive strength and density, while an increase in the concrete porosity were observed. In General, this study showed the validity of the proposed method to be further investigated for safe disposal of consumed photovoltaic modules.
