This book deals with existing technologies of solar energy conversion as well as novel methods under consideration in academic and commercial R&D sites. The experimental results presented in the work are well crafted by both analytical and first-principle numerical simulations. The book highlights the real potential for economically justified use of solar energy at every household and/or commercial solar farms. The ever-improving methods of thin-film epitaxial growth combined with a better understanding of the sun light absorption and antireflection are highlighted. While there was a period when the material quality was considered to be cornerstone of the conversion efficiency followed by substantial efforts to optimize multiple-cell architecture, it became clear that many old ideas such as variable band gap, multi-junction intrinsic region, as well as solar tracking mechanisms offer new possibilities for improved harvesting of energy. Amplifying the importance of materialsselection efficient design of the photo-voltaic elements various aspects of the production cost and the impact on the environment are discussed. In addition, the eligibility of the proposed production technologies in the current photovoltaic market are evaluated and confirmed.

Presents the latest research on the subject of solar cell technology and energy harvesting Features designs of advanced photovoltaic units Discusses novel thin-film methods with high potential for solar energy harvesting

At age 23 he was the youngest professor of Semiconductor Electronics Department at Polytechnic College of Kherson (Ukraine). Working as a member of the research staff in the Institute of Solid State Physics, Russian Academy of Science, he received in 1971 the First Prize of ISSP of the Russian Academy of Science for the discovery of dislocation based p-n junctions in Si and Ge. In May 2015, for achievements in research, Prof. S. Mil'shtein was elected to be a member (Academician) of Academy of Science, Republic of Kazakhstan. Prof. S. Mil'shtein served as member of organizing committees at numerous international conferences on microelectronics and nanotechnology. His publication list carries over 300 publications, patents, and conference presentations. His current research work covers high speed quantum electronics, design of solar sell systems, imaging systems for biometrics and medical engineering applications. Dhawal Asthana graduated in 2017 from Madan Mohan Malaviya University of Technology (MMMUT), Gorakhpur, India with a bachelor's degree in Electrical Engineering. After completing MS in Electrical and Electronics Engineering from University of Massachusetts, Lowell, in 2019, he has been conducting research as a doctoral student of Electrical Engineering as an advisee of Prof. Samson Mil'shtein at the same university. While his doctoral dissertation focuses on integration and synchronization of solar PV and wind power generation for microgrid and DG scale systems; over the span of his academic career, he has co-authored 15 publications and co-invented 2 upcoming patents that cover the diverse fields of solar photovoltaics, electric vehicles, wind energy, machine learning, electronic devices- RF HBTs and GaN HEMTs and optoelectronic devices. As a graduate student at UMass Lowell, he was a recipient of the Provost Graduate Fellowship in 2017. Being a member of the Editorial Board (2014-2017) at MMMUT, Gorakhpur, he also served as an editor for the monthly newsletter and annual magazine of the university.
