The rapid development of sustainable energy is today demand for the development of nation because of their vital role in development of solar, wind, and much renewable energy. Photovoltaic (PV) is natural inhabitant and support natural environment and reduce the harmful fuel consumption. In India there are nearly 256 days of clear sunny sky per year so enormous amounts of solar energy are available, but it is limited because of low efficiency. PV performance efficiency is drastically affected by variations in sun irradiation, shading effects, and excess temperature rise of solar cells. These are the prominent reasons behind the deflection of solar panel maximum power point (MPP) that causes a reduction of overall efficiency. In this chapter, we describe how the system efficiency can be monitored continuously to improve the output by using IoT and vision sensors [2].
The Fourth Phase of Water
Published in Aruna Bakhru, Nutrition and Integrative Medicine, 2018
Energy harvesting seems straightforward: light drives the separation of charge, and those separated charges constitute a battery. Harvesting electrical energy should be realizable with proper electrodes. This (patented) technology development has the potential to replace standard photovoltaic systems with simpler ones based on water. More detail on these practical applications can be found on the Pollack laboratory homepage: http://faculty.washington.edu/ghp/.
Saving the human race: environmental sustainability

An enormous additional advantage of photovoltaic modules is that they can be used to supply power in remote and sparsely populated areas where it would not be cost-effective to pipe in electricity. Not only would this be a major advantage to LDCs, which clearly cannot afford expensive power infrastructures, but also it would benefit temperate developed countries by creating the possibility of transferring power from tropical areas.

Nanotechnology has evolved as a seminal platform for drug packaging and delivery over the last few decades in biomedical science. Throughout these years, the versatility of nanoparticles (NPs) has contributed toward their functional capability as nano-drug carriers. NPs are particles between 1 and 100 nanometers in size, which can be classified as carbon-based, inorganic, and organic NPs [1–3]. Carbon-based NPs are nanoparticles solely made from carbon atoms [4]. They are commonly used in drug delivery [5], energy storage [6], bioimaging [7] and photovoltaic devices due to their distinctive electrical conductivity, high strength, electron affinity, optical and thermal properties [8,9]. Meanwhile, inorganic NPs are made of metals, ceramics, or semiconductors [1]. They are well-suited for theranostic applications due to their unique electrical, magnetic, and optical properties [10]. Organic NPs are nanoparticles made of proteins, lipids, carbohydrates, and polymers [11]. Typically, organic NPs are nontoxic and biodegradable, hence they are often used in targeted drug delivery [4] and cancer therapy [12]. However, these synthetic NPs have limited biocompatibility and efficiency in clinical applications [13].

There is a need to fully understand the ecotoxicological impact of cerium oxide thin films on the aquatic environment. Conflicting reports are published (Pelletier et al. 2010; Kuang et al. 2011; Leung et al. 2015) about CeO2 nanoparticle toxicity. Several groups report toxicity toward bacteria (Pelletier et al. 2010; Kuang et al. 2011), algae (Rodea-Palomares et al. 2011), plants (Cassee et al. 2011), soil nematodes (Roh et al. 2010), and epithelial and cancer cells in human lungs (Lin et al. 2006). It is also proposed (Asati et al. 2010) the possibility of controlling of toxicity of CeO2 by modulating the surface charge with a polymer coating. Due to their high chemical activity and stability, CeO2 was an excellent catalyst for the photodegradation of ciprofloxacin, widely used fluoroquinolone antibiotics (Liu et al. 2016; Oropesa et al. 2018). However, it should be noted that the above studies related to toxicity and antimicrobial properties of CeO2 have been done for nanoparticles only. No such study related to thin films CeO2 would be important in the photovoltaic and window applications.

Missions thinking builds on a systems approach by recognizing the interconnected nature of the economy, public sector and private enterprise. This approach does more than just scale AT, but rather creates and highlights an AT innovation ecosystem which supports economic and social change. Government is a key player in driving forward the economy if it is recognized and seen as such. An example would be that through a mission approach, AT demand could possibly be stimulated through the integration of services via the incorporation of procurement and provision of AT within health and social care systems. The focus of a mission is based in innovation economics. Rather than viewing AT only through the lens of health and social perspectives, it places AT from the vantage point of technological change and innovation. Directed innovation and growth within the AT sector, which would result in successive waves of further AT innovation, would result in cheaper and higher quality products. As was the case with investment and innovation in solar photovoltaics when there was national green economy investment (Mathews, 2019). Missions would help to address current challenges found within the innovation domains of product, supply and procurement by bringing together stakeholders and enhancing public sector interest and investment (Albala et al., 2021).
