    Fill factor of a photovoltaic cell

    alright, it seems that no one seems to know. but i just want to know that whether the maximum power of a photovoltaic cell can be obtained thru simple experiments or does it require some very high end equipments

    Fill factor of a photovoltaic cell

    I basically want to identify the fill-factor of a photo voltaic cell by calculating the ratio of maximum power (Vmp x Jmp) divided by the short-circuit current (Isc) and open-circuit voltage (Voc) in light current density. 1. How am i suppose to set up the circuit, should a voltmeter be...

    Calculating the energy of light

    im planning to measure the maximum power by plotting a graph of current against voltage. i don't think this circuit if mine is right http://img99.imageshack.us/img99/9167/97481115ua3.th.jpg because I've been getting 0V when the resistance box is turned on. but when i remove the resistance...

    Calculating the energy of light

    does solar cell the dimension of 10cm x 10 cm differ from a photocell ? when a solar cell that receives light from a sun is called solar cell and any other light source would be called photo cell , is that right ? thanks

    Calculating the energy of light

    Okay, I am doing experiments on calculating the energy of light by measuring the voltage on a voltmeter. Now, I am varying the wavelength of the light by using filters of different colours. Will i be able to get different readings if i use a milivoltmeter ? Also, once I've gotten the readings in...

    What property of light does the photoelectric effect display?

    how do i calculate the energy emitted by different wavelengths of light ? is it possible to do an experiment that uses a photovoltaic cell to measure the voltage produce by directing light of different wavelengths ?

    Effects of temperature towards conductivity

    Ok, i am given this task by my physics group leader and is required to do an experiment based on the following research question: To investigate the effect of temperature to the conductivity of a charcoal rod. i. How do i heat a charcoal rod to a desired temperature and make it remain...
