I understand the photoelectric effect, but if such panels were powered by 
electron emission, how do they last so long? Why doesn't the material 
become completed ionised within a few months? And how we ensure that the 
incoming light is always above the required threshold frequency. Which 
materials are used for low energy work functions? Hope that's not too many 
questions. Thanks!
