Electronics Applications in Nanotechnology

Copper Oxide Solar Cells

Power(Watts) = Voltage(Volts) x Current(Amps)

Measure the Surface Area of the copper oxide

Area(meter2) = Length(meter) x Width(meter)

Power of solar cell =______________ W

Surface Area of the copper oxide = ______m2

Sun’s Energy = 1000 W/m2

Calculate the Efficiency of the cell

%Efficiency = Power(watts)

Sun’s Energy(Watts/meter2) x Surface Area(meter2)

Efficiency = _______________%

Compare the Surface Areas of these cells

A= length x width + 2πrh = 20.78

A= length x width = 9

Although the Efficiency should stay the same, increasing the Surface Area is a valid strategy to make an inefficient cell usable.
