Who cares about efficiency or size?
I mean that seriously. Right now, pretty much all that matters is cost per watt. For normal terrestrial uses, a 20% efficient cell loses out to a 5% efficient cell that's 10x cheaper. (Numbers made up on the fly with no particular basis.) We're not currently hurting for space for these things, and sunlight is free.
