1. estimate the relative efficiency between the bigand small solar cells using tungsten lamps. how do you make surethe measurement is as accurate as possible?
2. find the capacitance-frequency and capacitance-voltagecharacteristics of different types of solar cells. what does thedata means in terms of physical process within the solar cells andwhy it so different from each other? carry out the measurement inbright and dark environment.
3. measure the iv characteristics of different solar cells. whatare their open circuit voltage, closed circuit current and the fillfactors? why are these values so different between different typesof solar cells? (hints , answer might be able to be found from2)
