The transition to sustainable transportation has fueled the need for innovative electric vehicle (EV) charging solutions. Building Integrated Photovoltaics (BIPV) systems have emerged as a promising technology that combines renewable energy generation with the infra‐structure of buildings. This paper comprehensively reviews the BIPV system for EV charging, focusing on its technology, application, and performance. The review identifies the gaps in the existing literature, emphasizing the need for a thorough examination of BIPV systems in the context of EV charging. A detailed review of BIPV technology and its application in EV charging is presented, covering aspects such as the generation of solar cell technology, BIPV system installation, design options and influencing factors. Furthermore, the review examines the performance of BIPV systems for EV charging, focusing on energy, economic, and environmental parameters and their comparison with previous studies. Additionally, the paper explores current trends in energy management for BIPV and EV charging, highlighting the need for effective integration and recommending strategies to optimize energy utilization. Combining BIPV with EV charging provides a promising approach to power EV chargers, enhances building energy efficiency, optimizes the building space, reduces energy losses, and decreases grid dependence. Utilizing BIPV‐generated electricity for EV charging provides electricity and fuel savings, offers financial incentives, and increases the market value of the building infrastructure. It significantly lowers greenhouse gas emissions associated with grid and vehicle emissions. It creates a closed‐loop circular economic system where energy is produced, consumed, and stored within the building. The paper underscores the importance of effective integration between Building Integrated Photovoltaics (BIPV) and Electric Vehicle (EV) charging, emphasizing the necessity of innovative grid technologies, energy storage solutions, and demand‐response energy management strategies to overcome diverse challenges. Overall, the study contributes to the knowledge of BIPV systems for EV charging by presenting practical energy management, effectiveness and sustainability implications. It serves as a valuable resource for researchers, practitioners, and policymakers working towards sustainable transportation and energy systems.

“…The purpose of modifying the materials is to narrow the bandgap of the semiconductor and, consequently, increase its efficiency. Table 2 lists the semiconductor band gaps [12] and cell efficiencies under STC (Standard Test Conditions): the global AM 1.5 irradiance (1000 W/m 2 ) and at a cell temperature of 25 °C [13][14][15][16][17][18][19]. The width of the energy gap in semiconductors may vary ±10 % with temperature variation.…”

In today’s world, fossil fuels, including coal, oil, and gas, are the primary energy sources from which electricity is obtained. As they are exhaustible and their exploitation has a negative impact on the natural environment, they should be, at least partially, replaced by renewable energy sources. The implementation of this goal depends on a number of factors, including social and political, the existence of investment support programmes, and the need to lower electricity prices and ensuring energy security. One of these sources is solar energy. Each year, the Earth receives around 1 · 1018 kWh of solar energy, which is more than 1000 times the current global energy demand. This is therefore a vast source of energy that can be tapped to satisfy human energy requirements. The use of solar energy releases no CO2, SO2, or NO2 gases, and does not contribute to global warming. Photovoltaics is one of the technologies that makes it possible to generate electricity in an environmentally friendly manner. By using the energy of solar radiation, a photovoltaic cell converts energy without emitting harmful substances to the atmosphere, noise, and waste. Photovoltaics is the cleanest technology among all the technologies that use renewable energy. Considering the shorter and shorter times needed to generate energy equal to that required by the module production process, during its lifetime it will produce much more electricity than was used to produce it. This results in a reduction in greenhouse gas emissions. For example, during its lifetime, a 200 Wp module prevents the emission of over four tonnes (Mg = 106 g) of carbon dioxide. Although the technologies for the production of photovoltaic cells and modules entail a lower environmental burden compared to other sources of electricity, it is necessary to remember about the risks associated with the use of chemicals at the stage of module production, which threatens their release to groundwater or air, and the need to recycle modules after their disassembly. Also, the energy consumption in the production phase of PV systems significantly worsens the ecological balance. This article presents an analysis of the impact of the materials and technologies used on the result of the environmental analysis of PV installations. In the article a detailed energy balance analysis of the EPBT value has been carried out. The values of greenhouse gas emissions throughout the life cycle of the solar module were determined. Methods of limiting the impact of photovoltaic technologies on the natural environment were indicated.

These energetic particles, such as electrons, protons, neutrons, X-rays, or gamma rays, induced damage in materials (used in electronic devices) through total ionization and displacement, [4] which would affect the reliability of the electronic devices. [5][6][7] Electronics failure occurs in harsh and inaccessible environments through various paths, such as electromagnetic waves, nuclear reactions, and high-frequency communications systems. Therefore, the radiationhardened requirements of the deployed electronic technology depend on the specific high-energy photons and particles in the radiation environment. For example, Mars exploration requires a special proton anti-radiation in electronics. At the same time, the safety supervision and inspection of the contaminated nuclear area are suggested to be equipped with high resilience towards the alpha, beta, and gamma rays. The development of radiation-hard electric circuits over the years has led researchers to consider the application of functional anti-irradiation material to devices. The current focus is on developing complementary metal-oxide semiconductors (CMOS) with wide bandgap semiconductors (WBGs), which are well suited to large-area aerospace applications. [8][9][10] As shown in Figure 1, a notable material class of WBGs can be listed as metal oxides (MOS), transition-metal dichalcogenides (TMDs), silicon carbide, gallium nitride, and others. WBGs materials contribute robust properties under harsh conditions due to their strong electronic compliance, high-temperature competence, and strong atomic bond energy. [11][12][13][14][15][16] They have been proposed as favorable materials for aerospace and other radiation-hardened applications. Generally, the bandgap in the semiconductor reflects the extra energy that a valence electron must access to become a free electron. Its large bandgap of more than 3 eV guarantees inherent reliability in the semiconductors, providing transparency for the low-energy photons. The large, spherical nsorbitals in the conduction band (CB) of MOS also play a critical role in high dopability for hosting a high density of electrons, leading to the remarkably tolerance to various radiation fluences. [17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35] Understanding the apparent immunity of the WBGs to various radiation environments and radiation-hard electronic engineering would be critical for pushing the technology further and understanding its limitations. Efforts to address these issues have been underway over the past two decades. Substantial progress has also been made in designing radiation-hard thin films transistors (TFTs) with ZnO, Ga 2 O 3 , In 2 O 3 , SnO 2 , IGZO, SiC, GaN, and many other WBGs, The aspiration of electronic technologies that are resistant to high-energy cosmic radiation is essential for current harsh radiation environment exploration. Integrated circuits mostly require post-processing after designing, making their structures more complex than the standard systems. Thus, unique de...
