Solar energy has certainly gotten much, much cheaper compared to decades ago, but there's only so much cheaper left to go before it reaches market price of plain sheet glass.
Collection efficiency is occasionally climbing a percentage point or two, but that's not an open end like a gut feeling raised on Moore's law might suggest. Even the hypothetical 100% cell that will never exist would not be a single order of magnitude better than what we have.

On retail, photovoltaics already passed glass in lots of places. But it doesn't need a lot of change to make it unequivocally cheaper than plants. Just the little margin of what we can do with the current design suffices.
