Solar photovoltaics (SPV) forms an integral part of renewable energy systems that are crucial for combating global warming. Written to serve as an ideal text for students, researchers and industrial personnel, it discusses the principles of operation of photovoltaic devices, their limitations, choice of materials, and maximum efficiencies. It covers in depth discussion of new materials and devices based on organics and perovskites, and a flow-chart of the manufacture of Si, GaAs and CdTe cells, their characterization and testing. It highlights characterization, testing and reliability of solar PV modules, comparison of fixed and tracking SPV systems using concentrator cells. Economical aspects of grid-connected and stand-alone systems and a wide range of applications, from solar pumps, and street lighting to large power plants is covered in the text. Several aspects such as cell and module manufacture, characterization, testing, reliability, and system design are described considering commercial SPV manufacturing plants.

Islam is the complete code of life. It addresses issues, pertaining to almost every walk of life. Polity, economy, society, family, education human rights, self and national defence, inheritance, science, philosophy, religion spirituality, moral values, communal harmony etc. In fact, not a single subject has been spared, which does not find mention in Holy Quran and Traditions of Prophet Muhammad (Pbuh). Prophet''s teachings are all based on the Divine Revelations, made by Allah, the Exalted, through the medium of archangel Jibrael from time to time. The first revelation was made in the cave of Hira, when the Prophet (Pbuh) had completed four decades of his life. The cave event is, in fact, the manifestation and systematic declaration of the prophethood, which he had been endowed since birth. Completion of forty years of age is the time, when as a principle, prophethood is systematically declared and pronounced. Since the Prophet (Pbuh) was not formally literate, he never said anything on his own. Select criteria helped in sorting out his sayings, with authenticity and genuineness from amongst a plethora of mix sayings. Finally, about one lakh and fifty thousand sayings were sorted out, which have been collected into six books, based on Prophet''s teachings. Encyclopaedia of Prophet Muhammad''s Teachings is a multi-volume work, based on research and meticulous findings. Comprehensive, extensive exclusive and holistic, as it is, it must create an urge in all quarters of Islamic scholars to possess it.
