how to build phone solar charger

requirement:
Glass surface
Solar cells
Soldering iron
Battery holder
Diode
1
Construct a backing out of glass
for the solar panels. One option
is to use an old window that you
have cleaned to ensure the light
can pass through.
2
Arrange the solar cells on the
window or glass to determine
the best configuration for your
surface. Solar cells usually will
have a backing that will allow
you to connect them to the glass
surface.
3
Solder the cells that are in a
single row together, soldering
the positive leads to the negative
leads. Connect the two rows of
cells by using a wire to connect
the positive lead on the front of
one row the negative lead on the
back of the other row. If you are
using more than two rows,
repeat this process.
4
Use a battery holder taken from
a broken appliance, such as a
radio or flashlight and attach the
positive end of the array to the
red lead of the battery holder and
the black lead to the negative end
of the battery holder.
5
Attach a blocking diode to the
negative lead attached to the
battery holder. This will prevent
outflow of the electricity from the
battery back to the solar array. It
can be attached by simply
twisting it onto the lead.

Hi Enginer! Please what is solar cells and can I get it? Secondly in number 3 you said "if you'r using more than one rows", what did you mean by that? Finally, is it the flashlight battery that will be charge or still have to connect it with mean battry?
