Engineers at the University of
                   Florida are developing an
                   inexpensive method of making a
                   new type of exceptionally thin and
                   inexpensive solar cell they expect
                   will make solar power the main source of electricity
for the new millennium.

 ...and since it's been just over 4 years since that announcement was made,
there's now less than 6 years to go before all our electic problems will be
solved!

but it makes sense to paint outside walls of your house with
solar-cell-paint given invented, to make you forget your energy bills
forever.
 
1 , 2 or even 6 year-time is not so distant for an owner of new house
still under construction.

so should we right now forget solar-cell panels and build our new
hourses entirely as one GIANT SOLAR-PANEL ?

I suspect the "paint" is being a bit hyped.
I have not actually read the articles in question (net problems)
however, while it may sort-of be paint, applied in layers, to make solar
cells, it's going to be really hard to get it working so you can apply
it directly to walls, rather than to flat panels in a factory.
For example, to get power out, you need a couple of electrodes on either
side.
Shorts caused by pinholes through the cell, and opens caused by cracks
in the current collection layers will both cause inefficiancies.

It's not going to be something you can simply paint on house walls,
somewhat like you can't get "Mona Lisa" paint that you roll on and
out comes a copy of a famous picture.
