    Effect of panel materials on the performance of solar cells
    (Palarch’s Journal of Archaeology of Egypt/Egyptology, 2020) Thangalakshmi, S.; Ganesh Ram, V.; Sivasami, K.; Sathiyasekar, K.
    Electrical energy has become part and parcel of our life as all the domestic modern appliances use electricity because of its cleanliness, availability and ease of control. Also, conservation of such energy is paramount not only on economic aspect but also to extend the life of resources for further use. Presently, most of the electricity is generated using power generating plants that use coal as fuel. In addition to produce energy, they do contaminate the environs by discharging flue gases chiefly carbon dioxide. The extent of carbon dioxide discharged into the air as an end result of actions of a specific individual, group or public is referred as carbon footprint and globally there is a call for reducing this carbon foot print to curtail its unfavorableimpacts on the society. Hence, though there are other resources like oil and gases are available for producing electrical energy, they do have the same effect. They are unsustainable. More than conserving the energy, it is highly needed to use renewable and sustainable energies to produce electricity. The cheap, clean and available renewable energy is solar energy. Photovoltaics (PV) is a guileless and smart method of hitching the solar energy. PV cells/solar cells are exclusive in that they reliably deliver electricity through the solar radiation hitting them. All the solar radiation falling on a PV cell or panel is not completely converted as electrical energy but it is decided by the materials used for PV cells. There are various other factors that judge the outcome of a solar panel namely, the temperature, solar irradiance, fill factor etc. The aim of this study is to explore and relate the various materials used for PV panels based on their properties and other significant factors. This will serve as a guide for researchers for choosing a proper material for a particular application.

    Prevalent glitches in generation of solar power using PV panels - An Indian scenario
    (Journal of Advanced Research in Dynamical and Control Systems, 2020) Thangalakshmi, S.; Sivasami, K.; Sathiyasekar, K.; Preetha, M.
    There is a promising opportunity for the sustainable growth of solar power is in our nation. The distinctive energy from sun received by the earth for one year is only about five thousand trillion kilowatt-hour. It is perceived that mainstream of those areas get 4-7 kWh/m2 for every 24 hours. The accessible solar energy can be pragmatically used to warm system/space heating and even to structure electrical energy by means of solar-thermal and solar-photovoltaics. Besides, there is a massive prospective to proliferate the photovoltaic power in our country. The admiring quality of solar is that it can as well be manufactured as distributed power, which agrees for adding on to the standing capacity within a short extent of time. Electrifying the rural regions can be well implemented via solar distributed power and it is applied for heating and cooling of villages, communities, townships and metropolitan areas in addition to the supply of electricity. The solar is ultimately safer than other modes of generating electrical power. Rather, even a tiny portion of collected solar energy may feasibly oblige the needs of the entire nation though it allude to concrete intricacies. Thermal power manufacturing is widely applied in the present-day Indian condition using coal as base material because of its economic aspects. By the long-term and persistent research work and introduction of new-fangled skills, solar energy can be produced at considerably minimum cost. This paper projects the principal challenges/barricades in attaining solar power in India, predominantly through photovoltaics, which could help as a valuable guidance for the solar engineers and lay concrete on the way of fetching the solar electric power and other applications appropriately.
