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
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...
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

because I've been getting 0V when the resistance box is turned on. but when i remove the resistance...
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
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...
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 ?
im trying to make a lantern float but what kind of formulas should i consider in trying to make it float? i want it to be like this. http://upload.wikimedia.org/wikipedia/commons/9/94/SkyLanternRichy01.jpg
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...
