Solar Energy is the future in India and is already emerging as the present in Hyderabad as the GHIAL is already running 50% on Solar Power. Many organizations are adopting or fully running on solar resources. The scientists are already working extra hours and doing everything they can to be a part of the Indian government's plan to launch a deep ocean mission in 2022.
The researchers and scientists from Birla Institute of Technology(BITS) Pilani's Hyderabad campus have found that solar cells could be used in the monitoring sensors for commercial and defense purposes in Submarines. The researchers from IIT-Kanpur have also combined with the people from BITS Hyderabad and have studied the characteristics of silicon solar cells in different underwater settings.
This program is funded by Defence Materials and Stores Research and Development Establishment (DMSRDE), Defence Research and Development Organisation (DRDO). The Assistant Professor at the Department of Electrical and Electronics Engineering at BITS has claimed that there is enough solar energy to help run these submarines underwater. To identify and prove this claim, the researchers coated various solar cells with polydimethylsiloxane (PDMS).
This material is highly transparent and has high light absorption properties, and is hydrophobic. The researchers at BITS have done a lot of research on testing these solar cells. They created a mini water bed in their campus and filled it with de-ionized water, lake water, natural seawater, and artificial seawater and tested the efficiency of these cells in different conditions. The research is still on, and a deeper study of many other cells will be conducted before fixing the most efficient cells that can be employed.
