ABSTRACTPresently, Malaysia is fostering growth in the green energy sector in order to reduce its carbon emissions and contribute in the fight against global warming. Renewable Energy (RE) such as solar cell could no longer be considered as a green technology because at the end of their lifecycle, they become non- biodegradable waste which in turn constitutes pollution and contributes to global warming. Thus, the aim of this research is to study a self-sustaining solar module produced by upcycling solar cells from non- biodegradable waste. Several solar cells from electronic devices were reused in this study. The results obtained show that a combination of 4V, 3V and 2V reused solar cells produced 10.20V and 47.9mW of power. This indicates that the proposed upcycled solar module is feasible and has the potential to aid in the promotion of clean and renewable energy use in order to attain the desired sustainable development goals.Keywords: solar module, self-sustaining, solar cell, non-degradable waste

Abstract The tourism industry has been long blamed as the major driver to global warming due to it being the largest industry that uses more energy, most of which comes from sources that emits carbon-dioxide. However, despite all the blames on tourism for its negative effects on the environment, less work has been done to ascertain its impact on the environment. Unlike past studies that that alludes that tourism development exacerbates the emission of carbon-dioxide hence global warming, the current research shows that in the OECD countries, tourism does not have any significant link with greenhouse gasses emissions. This is so because OECD nations have long started to shift from fossil fuel use, as sources of energy, to renewable energy use which doesn’t exacerbates greenhouse gasses emissions. However, the current research concurs with the findings of past studies that renewable energy consumption significantly decreases greenhouse gases emissions. Using renewable energy sources of energy instead of fossil fuels should continue to be encouraged in all nations for the purpose of achieving low carbon in the future. The current study uses dynamic GMM model for 38 OECD countries from 2008 to 2019. Dynamic GMM model remains one of the best models since it corrects endogeneity problem in a model. GMM model overcomes autocorrelation, heteroskedasticity and normality problems, hence the robustness and reliability of results obtained. Gross Domestic Product and population size negatively affect greenhouse gasses emissions while inflation rate is observed to have a significant strong positive link with greenhouse gasses emissions.

Green Cities

This study aims to estimate and explore the experience of introducing renewable energy use in the context of the world’s smart cities. In this regard, the study points out that the use of green energy is an important part of sustainable development. Environmental problems are a matter of global concern. Hence sustainable development is one of the approaches to end the harmful anthropogenic impact. The work includes quantitative assessment methods, for example, statistics, quantitative analysis, analogy, and synthesis. As a result, the analysis confirms that the effective development of a smart green city is impossible without the introduction of several renewable energy sources, the integrated use of which will reduce the likelihood of problems with the city’s energy supply. Likewise, the outcome accentuates that the desire to fully switch to renewable energy sources (RES) can be accompanied by several problems as the creation of RES technologies does not always take the risk of abnormal situations into account. In conclusion, the research findings are recommended to be taken into consideration by researchers in the field of smart and sustainable cities development, as well as urbanists and economists for designing future smart green cities based on renewable energy sources.

The Impact

Purpose The purpose of this paper is to investigate the behavior of interconnections between solar cells in a glass-free solar modules. As glass weight can be a limitation, it is still interesting to investigate other types of systems, especially when the glass was replaced with a polymeric front sheet. Such systems can be more sensitive for the solar cell interconnection ribbon fatigue. Design/methodology/approach To examine this effect, the set of glass-based and glass-free modules were prepared using various ribbon thickness and treatment concerning its stretching or curving before lamination. Furthermore, additional reinforcement of the connection between the ribbon and the solar cell was proposed. The prepared modules were exposed to the cyclic temperature variation in the environment chamber. The number of cycles after which the interconnection maintains its conductivity was noted. Findings Changing the outer layers into more elastic ones requires additional care for the ribbon treatment because interconnections become more sensitive for a system relative displacement. To secure interconnection before fatigue an additional curving of ribbon between solar cells can be introduced whereas the best results were obtained for a system with aluminum plate laminated as an interlayer. Originality/value The paper presents a new system of a glass-free solar module based on epoxy-glass fiber composite as a backsheet. The glass front sheet was replaced with an elastic, transparent polymer. Such construction can be used in a system where the glass weight is a limitation. As glass has a structural function in traditional modules and limits fatigues of interconnections the proposed system requires additional ribbon treatment to preserve long module life-span.

Laser Scribing

Laser scribing is an important manufacturing process used to reduce photocurrent and resistance losses and increase solar cell efficiency through the formation of serial interconnections in large-area solar cells. High-quality scribing is crucial since the main impediment to large-scale adoption of solar power is its high-production cost (price-per-watt) compared to competing energy sources such as wind and fossil fuels. In recent years, the use of glass-side laser scribing processes has led to increased scribe quality and solar cell efficiencies; however, defects introduced during the process such as thermal effect, microcracks, film delamination, and removal uncleanliness keep the modules from reaching their theoretical efficiencies. Moreover, limited numerical work has been performed in predicting thin-film laser removal processes. In this study, a nanosecond (ns) laser with a wavelength at 532 nm is employed for pattern 2 (P2) scribing on CdTe (cadmium telluride) based thin-film solar cells. The film removal mechanism and defects caused by laser-induced micro-explosion process are studied. The relationship between those defects, removal geometry, laser fluences, and scribing speeds are also investigated. Thermal and mechanical numerical models are developed to analyze the laser-induced spatiotemporal temperature and pressure responsible for film removal. The simulation can well-predict the film removal geometries, transparent conducting oxide (TCO) layer thermal damage, generation of microcracks, film delamination, and residual materials. The characterization of removal qualities will enable the process optimization and design required to enhance solar module efficiency.
