Don't "may be" or "if", show me your design, if you can't then we must assume the amount of Si or QD used in each solar panel of the same wattage output is the same except QD PV cells will be at least twice as efficient.
Take a Si PV cell 250-watt solar panel as an example, it contains 60 PV cells, each cell has 0.513 Volt and 7.82 Ampere output. The voltage output is proportional to the length of the track, the current output is the sum of the tracks connected in parallel. In the Si PV cell the track is thicker and generates higher current, in the QD PV cell the printed QD track is very thin and generates less current (if it will generate the same current as in Si, the fine track will be burn out), so more tracks connected in parallel is needed to generate the same current as in Si PV cell, as a result, the among of QD used per panel will be about the same as that in Si.
There is absolutely no way just one microscopic fine printed QD track can generate 7.82 amperes, just 0.5 ampere will burn out that track, it needs many tracks each generates only milliampere connected in parallel to generate 7.82 amperes, that means a lot of tracks and a lot of quantum dots.
