Why are we not using solar power cars?

I see cars every day ejecting their toxic fumes into the air, when I go to school. It strikes me why can’t everyday transport like cars be solar powered? I live in India, Kolkata to be precise and believe me there is plenty of sunlight on the road, but still diesel powered cars are used. I want to know is the cost of installation of such solar powered cars way more than the cost of diesel? Please help.
