I remember from my second year Semiconductor course that you can't just use any sand to get silicon.
Though new solar cell materials are being found all the time. For instance, the material I work with for my PhD work has recently (In the last few years) has been found to generate an EMF upon heating etc. It's completely impractical at the moment as it's not the easiest material to work with though.
