This is why you need to cover your whole roof with cells to power your light bulbs, and why solar power plants would have to occupy tens of square miles of desert to produce as much power as a nuclear power plant. To combat this issue, MIT has built 3D stacks of photovoltaic cells.
Basically, photovoltaic cells themselves aren't all that expensive -- according to MIT, they're only around 35% of the total cost of a solar power installation. The main issue with solar power (and its main cost) is its low energy density, and thus the sheer surface area required to generate a sizable amount of electricity.
