Article Citation - WoS: 3Boşluk İletim Tabakasız ve Esnek Organo Kurşun İyodür Perovskit Güneş Hücresinin Çevresel Etki Değerlendirmesi(Gazi Üniversitesi, 2022) Sarıaltın, HüseyinPerovskit güneş pilleri (PSC) esneklik ve düşük maliyetli rulodan ruloya üretim gibi avantajlarla birlikte son zamanlarda güç dönüşüm verimliliğinde de önemli bir ilerleme kat etmiştir. PSC'lerin ticarileştirilmesinden önce çevresel performansının yaşam döngüsü değerlendirme (LCA) yöntemi ile araştırılması önemlidir. Bu çalışmada, literatür verilerinden istifade edilerek, esnek Polietilen tereftalat (PET) alt tabaka ve boşluk iletim katmanı (HTL) eliminasyonunu içeren çözelti bazlı organo-kurşun iyodür perovskit güneş hücresinin beşikten kapıya yaşam döngüsü analizi (LCA) gerçekleştirilmiştir. 1 m2 hücre alanı üretiminden kaynaklanan çevresel etkiler altı Uluslararası Referans Yaşam Döngüsü Veri Sistemi (ILCD) kategorisinde belirlenmiştir. Analizin sonucunda, en fazla etki değerinin yüksek elektrik enerjisi tüketimine sahip vakum biriktirme işlemi gereksinimine sahip olan alüminyum metal elektrot tabakasının imalatından kaynaklandığı bulunmuştur. Ticari fotovoltaik teknolojilerle karşılaştırma yapabilmek için en yaygın kullanılan çevresel göstergelerden birisi olan küresel ısınma potansiyeli (GWP), birim kWh elektrik üretimi için hesaplanmıştır. Buna göre, bu çalışmada incelenen HTL'siz esnek (HFF) PSC'nin ticari PV'lerle rekabetçi GWP değerine ulaşmak için 15-20 yıl cihaz ömrüne ihtiyacı olduğu bulunmuştur.Article Citation - WoS: 3Citation - Scopus: 4Environmental Assessment of Transparent Conductive Oxide-Free Efficient Flexible Organo-Lead Halide Perovskite Solar Cell(Taylor & Francis, 2020) Sarıaltın, Hüseyin; Geyer, Roland; Zafer, CeylanPerovskite solar cells (PSCs), one of the third-generation photovoltaic (PV) technologies, have recently become a very popular topic in photovoltaic research. This technology, which is a candidate for commercialization in the future, needs to be evaluated from an environmental point of view. The amount of electricity consumption is the most important factor that directly determines the environmental impact values of photovoltaic cell manufacturing. Transparent conductive oxide (TCO) coated glass is one of the major contributors to electricity consumption in PSC architecture. It is therefore useful to investigate the environmental profile of TCO coated glass-free PSC architecture with conventional PVs. One of the solutions to this issue is manufacturing PSC on a flexible substrate. Flexible PVs are considered to be one of the most promising candidates for mass production with its advantages of low-temperature manufacturing, higher efficiency with a lower weight, portability, and compatibility with a roll to roll fabrication. In this work, we show that the environmental impacts of a representative PSCs with a flexible substrate. While the energy payback time (EPBT) of the flexible PSC is already competitive with commercial PVs, the device must reach a 25-year cell lifetime for its global warming potential (GWP) to reach a reasonable range.Article Citation - WoS: 14Citation - Scopus: 14Life Cycle Assessment of Hole Transport Free Planar-Mesoscopic Perovskite Solar Cells(American Institute of Physics, 2020) Sarıaltın, Hüseyin; Geyer, Roland; Zafer, CeylanOrgano-metal lead halide perovskite solar cells (PSCs) attract attention due to their low cost and high power conversion efficiency. Some weak points of this technology are short lifetime, instability, and expensive metal electrode deposition. Eliminating the unstable hole transport layer (HTL) and using carbon-based materials as the counter electrode would address both. In this work, we present a cradle-to-gate life cycle assessment of two HTL-free PSC designs, which use solution phase deposition to achieve mesoscopic and planar structures. Environmental impacts of producing 1 m(2) PSCs are converted to impacts per kWh electricity generation assuming 5years of operational lifetime. We find that major impacts come from fluorine doped tin oxide (FTO) glass patterning due to the electricity consumption of FTO patterning and glass cleaning processes. Even though the electricity consumption when manufacturing both PSCs is similar, their different efficiencies make the environmental impacts per kWh of electricity higher for the mesoscopic PSC than for the planar PSC. Energy payback time values of planar PSCs and mesoscopic PSCs are 0.58 and 0.74years, respectively, and these values are shorter than those of commercial first and second generation solar cells. However, the global warming potential (GWP) values of planar and mesoscopic PSCs are 75 and 94g CO2-eq/kWh, respectively, and these values are still higher than those of commercial solar cells. To reach the GWP of commercial cells, the operational lifetime would have to be 8 and 10years for planar and mesoscopic PSCs, respectively.Article Citation - WoS: 5Citation - Scopus: 6A Novel Enzymatic Delamination Method for Sustainable Recycling of Crystal Silicon Photovoltaic (c-Si Pv) Modules(Elsevier, 2025) Karagoz, Sadik Can; Gundogdu, Tugba Keskin; Sarialtin, Huseyin; Celiktas, Melih SonerDue to the growing effects of global warming, there has been a surge in the demand for renewable energy sources. In particular, the most important player in this increase is the installation of photovoltaic (PV) modules. At this critical stage, it has become a priority to identify strategic approaches for the recycling of end-of-life PV panels with a strong focus on environmental protection. This study examined the impact of enzymatic delamination on the separation of the EVA (Ethylne Viniyl Aceate Co polymer) layer, a crucial stage in the recycling process of PV panels. Notably, this investigation is the first of its kind in the existing literature. To investigate this, delamination effects of lipase, laccase, and lecitase enzymes were analyzed according to experimental design methods. Furthermore, sunflower oil was employed for the first time in the existing body of literature to facilitate delamination, resulting in a delamination rate of 100 %. The environmental impacts of these biotechnological techniques, which serve as alternatives to the commonly used toluene, were also comparatively assessed by life cycle assessment (LCA) method to analyze the environmental impact. LCA methodology was performed from gate to gate and the Recipe impact methodology was used. Oil assisted enzymatic delamination method was shown to be an alternative from environmental point of view to solvent based method such as toluene.Article Citation - WoS: 3Citation - Scopus: 2Environmental Assessment of the Hydrogen Combustion Process in Non-Premixed Gas Turbines(Pergamon-elsevier Science Ltd, 2024) Sarialtin, Huseyin; Korucu, AyseUsing cleaner fuels, such as hydrogen and developing more efficient combustion technologies are crucial in reducing NOx and N2O emissions, contributing to environmental concerns like air pollution and global warming. However, studies focusing on gas turbines using H-2 as fuel often overlook the emissions resulting from H-2 combustion. Given that gas turbines play a significant role in electricity generation globally, even minor improvements in their efficiency can lead to substantial cumulative benefits. Therefore, this study aims to address this gap by conducting a comprehensive environmental assessment using the life cycle assessment (LCA) methodology. By evaluating the environmental impacts of emissions from the combustion process of a conventional gas turbine and comparing them with potential emissions from H(2)combustion, this research seeks to provide valuable insights into the overall environmental performance of these technologies and contribute to sustainable energy development efforts. There have already been several LCA studies on H-2 production. In this study, we have identified the potential emissions and environmental impacts of H-2 combustion in gas turbines and compared them with the impact values of H-2 production regarding reference studies. The result shows that emissions during combustion should be considered in the identified life cycle impact categories.
