Hi guys,

I’m a sort of a newbie in solar cell and researching on the topic on solar cell technology.. I’ve read some wiki sites and google it but the explanation seems too hard for me to digest.. Can someone help me answer the following? Thanks

1) Identify the majority and minority carriers in p-type silicon with n-type silicon solar cell?

2) Explain the term diffusion and drift current?

3) List and explain two reasons why photovoltaic cell has low efficiency?

Thanks for replying!
