 AGRIVOLTAIC: Challenges and Opportunities Kunal Chowdhury, Assistant Professor, Department of Renewable Energy, MAKAUT,WB.   Sustainability refers to ability of avoiding depletion of natural resources.   Considering different natural resources, fossil fuels are one of the key resources which are depleting continuously. Therefore, rigorous R&D activities on renewable energy resources are going on all around the world. One of the drawbacks of renewable energy is its distributiveness which leads to large area requirement. On the contrary for a population dense country, land is a prime natural resource and two basic needs related to land are energy and food. Energy is one of the central parameters of life after food. Even in food preparation the role of energy is inevitable. Access to the energy resources controlled by four parameters and these are availability, adaptability, acceptability and affordability. Solar power has the potential to meet all these requirements....

    SOLAR DESALINATION PLANT Sanjay Prasad, PG Student Department of Renewable Energy   1.     Introduction:   Desalination means the process that removes excess salt and other minerals from water in order to obtain fresh water suitable for human consumption and irrigation. Sometimes the process produces table salt as a byproduct.   2.     Need of Renewable energy for Desalination: The origin and continuation of humanity based on water. Water is one of the most abundant resources on the earth, covering three-fourths of the planet’s surface. However, 97% of the earth's water is the salt water in the oceans and 3% is fresh water. Population growth is one factor, not only the need for drinking water and sanitation but also the need to produce food. As climate change makes rainfall less predictable and drought more common, a growing number of countries are turning to desalination. The separation of salts from seawater re...

  Multi-Junction Solar Cells Iftikar Ahmed, PG Student, Department of Renewable Energy, MAKAUT   A multi-junction solar cell is a tandem solar cell with more than one p-n junction. In practice, this means that there are multiple layers of different semiconductor materials, each of which produces electric currents in response to different wavelengths of light. This means that, theoretically, multi-junction solar cells are capable of converting more sunlight that hits them to electricity when compared to single-junction cells. Multi-junction solar cells are capable of absorbing different wavelengths of incoming sunlight by using different layers, making them more efficient at converting sunlight into electricity than single-junction cells. While they have the potential to be many times more efficient than traditional solar cells,  The materials that go into a photovoltaic cell make a large difference on the cell's efficiency, as the band gap varies based on the mat...
