    Wow .. that is so green. Don't put all your eggs in one basket. Sadly, solar is going to be a dead end in that goal, as soon as the goverment funding fails. Solar heating (air, water, oil) is where the energy savings is, but it will still have to rely on something else as backup for cloudy days.

    Good luck with your project but I haven't got the foggiest idea. Doubt you will get many replies here as our members are generally oriented toward practical implementation and not the theory of solar PV.

    Thanks russ. My objective is: To obtain an Electrical Engineering integrating strong technical proficiency and contribute towards addressing the challenges of Global Warming by accomplishing energy efficient systems.
    I would be graduating after a year and would like to join a company which deals with renewable like solar. Can you suggest me a thread dealing with job prospective and if you can recommend me people with whom I can be in touch on linkedin or companies I sould follow. I really want to join in foirst solar as it is presented near my University.

    Question

    Hi Everyone:
    I am a undergraduate student I have a question from my course solar energy. I needed help in the following question . The question is:
    Q. Calculate the thicknesses of silver and silicon that will absorb  95% of 600 nm light that enters the surface. Do the results have any implications for silicon based solar cells?
    I am using the formula I=Io * exp(-alpha*x)
    where I=intensity of light (I)at any distance (x) into the material
    and Io is the light intensity at the top surface


    I calculated absorption coefficient(alpha) for silicon from the website http://www.cleanroom.byu.edu/OpticalCalc.phtml. and kept 'I' as 0.05 and Io as 1. and calculated x which came out to be 5.74 micrometer but I am not sure about the calculation and typically the solar cell has a thickness of 200 to 500 micrometer.

    Please let me know if I am right or wrong.
Working...
