    Vehicle integrated photovoltaics (VIPV) is gathering attention by researchers and industry alike to help in decarbonization of transport industry. While PV panels have been integrated to the vehicles to support auxiliary functions, their wide scale implementation is limited by their size, weight and rigidity. In this work we present a proof-of-concept method to produce bi-facial PV panels with fibre-glass reinforced composite fabric (GRCF) using vacuum resin infusion process. These modules are specifically designed for integrating with an electric car and to be used as a power source to charge the batteries. Mini modules are fabricated using two interdigitated back contact solar cells sandwiched between layers of GRCF sheets. The modules are prepared by drawing the resin under a suitable vacuum through the different GRCF layers and allowing the resin to cure at room temperature. The modules are prepared at room temperature without using a stringer or laminator. Three different metal end-strips are used to assess their performance in the finally prepared module. The modules are subjected to the damp-heat test to analyse the degradation in the modules and the suitability of the fabrication process. Results show that resistance losses and optical losses play a vital role in the final losses resulting from degradation of the modules. Finally, we have shown in this work that it is possible to fabricate such modules using low-cost technology. By fine tuning and scaling-up the process, it is possible to produce modules of any size which could further help in the rapid integration of c-Si PV modules in vehicles.

    The cumulative PV panel waste is expected to reach ≈8 million tonnes by 2030 and ≈ 80 million tonnes by 2050. This presents an opportunity to pursue new avenues in terms of recycling and improving the circularity of the PV panels. In this work we present experimental results for recycling c-Si PV panels using recently developed electrohydraulic shock-wave fragmentation (EHF) of PV panels. The EHF process allows for the recovery of all materials used in the manufacturing of PV panels. We use different types of panels for the recycling process and analyse the material recoverability in each condition. Further, we analyse the effectiveness of chemical treatment in isolating metals from the silicon obtained from recycled c-Si PV panels, providing an opportunity of recovering high quality metal and silicon. The separation process allows for the high-quality material recovery and could potentially improve the economic feasibility of the overall recycling process.

    The exponential increased use of PV panels for energy production would also lead to enormous volumes of PV waste that need to be dealt with in an environmentally responsible manner. In this work we present experimental results for recycling crystalline silicon (c-Si) PV panels using recently developed electrohydraulic shock wave-based fragmentation of PV panels. The electrohydraulic fragmentation process allows for the efficient delamination of the modules and subsequent recovery of almost all valuable materials used in the manufacturing of PV panels, without thermally decomposing the polymers and eliminates creation of any toxic or hazardous waste during the process. We study the impact of the type of panel, size of the feed material and process duration on the quantity and quality of material recovered after the process.

    Recycling end-of-life (EOL) silicon (Si) PV modules have gathered recent attention from researchers. PV modules can be recycled using a closed loop cycle where the materials recovered are reinjected into the supply chain for producing new modules. However, such solutions are extremely complex, expensive and could lead to further generation of harmful chemicals or emissions. Another way to recycle c-Si PV modules is by using them to produce other commercially important materials, for example ferrosilicon, using an easy and inexpensive route. Ferrosilicon is produced by reduction of silica using carbonaceous sources, which generates planet warming greenhouse gases. In this work, we present a simple method to use recycled Si (reSi) obtained from EOL PV modules to produce FeSi using induction furnace and no carbonaceous source. Along with reSi, metallurgical grade Si and commercial FeSi75 were also used to produce FeSi samples for comparison. FeSi samples with different silicon content were prepared. We also investigate the effect of the oxygen in the processing atmosphere, by preparing samples in arc furnace under argon atmosphere. The samples were characterized using scanning electron microscope coupled with Energy dispersive X-ray spectroscopy, to analyse the microstructure. X-ray diffraction was also used to identify and compare the phases formed in different samples. Hardness of the samples was also determined to understand the ease in the mechanical processing of the samples for potential commercial applications. Through the experimental results we have shown that silicon recovered from EOL PV panels could be used in the fabrication of FeSi.

    Global PV installations recently crossed the terawatt scale. The growth of photovoltaic (PV) installations is an important and desirable element in generating clean electricity and combating climate change. However, with increased use of PV panels for energy production enormous volumes of PV waste would be generated that would need to be dealt with in an environmentally responsible manner. In this work we present early-stage research results based on experiments conducted with recycling end-of-life (EOL) crystalline silicon (c-Si) PV panels promoting resource efficiency and circularity. We explore experimental pathways for both close-loop and open-loop recycling of EOL PV panels. For closed-loop recycling we present experimental results using the recently developed electrohydraulic shock wave-based fragmentation (EHF) of PV panels. The EHF process allows for the recovery of almost all valuable materials used in the manufacturing of PV panels. We further provide a succinct literature review for further downstream treatment of the end products obtained after EHF processing of EOL PV panels to recover precious metals such as Silver. For open-loop recycling, we propose using the panels in the production of ferrosilicon compounds, thereby reducing the emissions of greenhouse gases accompanied with their production. Through experiments it was onbserved that the size of the recycled Si does not impact the microstructure of the FeSi produced, which means that the technology could be easily used to handle different sizes of Si source. Through careful experiments and analysis we provide recycling methods to improve the circularity and resource efficiency in the management of end-of-life c-Si PV panels. Both experimental recycling pathways discussed in this work could potentially provide sustainable technical pathways to recycle EOL PV modules, which does not involve producing harmful greenhouse gases.
