ThermoElectric Device

Dhoni N

Designed and implementation of a setup to simulate underwater environment.
Underwater characterization using various solar simulators ( Xenon, LED, Mercury).
Characterization done with
- Different types of solar cells (monocrystalline, polycrystalline, amorphous, dye-sensitized, ferroelectric Heterojunction)
- Five different types of water like Normal water, DI water, Seawater, Prepared Seawater and Lake water.
- Different filters.
Key Validations/Observations:
- Power output of the solar cell decreases with increase in water depth because of the decrease in irradiation in all types of water.
- The power output of the solar cell decreases more with presence of high water impurities especially in case of lake water conditions.

a) Experimentation Scheme and Setups b) Study of Polycrystalline Si Solar cell
