1)What property of the space charge region contributes to the collection of charge carriers and which is not present in the neutral regions where movement and collection are by diffusion?
2)In a homojunction solar cell do light generated carriers have to go over barriers as do dark carriers to produce current?
3)For a solar cell with JSC = 20 mA/cm2 when a forward bias equal to the value of VOC is applied in the dark, what is the value of dark current(in mA/cm2 ) that flows?
4)We have discussed how the resistance of the grid lines is important to optimizing current flow. Which resistance term does this affect, series resistance, RS, or shunt resistance, RSH?
5)If all of the sun's energy were delivered at a single wavelength instead of the actual broad profile, would solar cells be more or less efficient?
