Efficiency = energy out as electricity / energy in as light
At full sun, there is approximately 1000W/m^2
Since your solar cell is not a square meter, you have to scale the answer.
Step 1 : Convert the Cell Area (mm sq.) to Meter Square
Step 2 : Divide the known wattage by the area M square
Example : If it is 156 mm x 156 mm Sq. Cell , then the Area would be : 0.24336 M. Sq
Now, if the Wattage is 3.86 Wp , then the efficiency would be 3.86 divided by 0.24336, = 15.86%

Does the area of a solar cell effect the voltage output?
It does :)
Can solar cells used in mobile phones?
No, cell phones draw too much power to be supplied by solar cells, unless you used a large solar panel. But you certainly can't build a solar cell into the back of the phone like you would a solar calculator. For example, one web source says a cell phone draws about 1 W. Another web source says solar panels can put out about 1.2 W for 100 cm2 in bright sunlight. So to power the cell phone you'd need a solar panel at least as large as a CD, probably more like a sheet of paper.
Is photo voltaic cell is an active transducer?
A photovoltaic cell is an active transducer. This is commonly referred to as a strain gauge or simply known as a solar panel.
Define Maximum power point tracking of solar cell under partial shading conditions?
in shading conditions also the solar raditions will reach the earth i think this will not effect the solar panels and also the mppt in shading conditions also the solar raditions will reach the earth i think this will not effect the solar panels and also the mppt
Why current will vary in a solar cell?
The current will of course vary with the intensity of the imparted light and with the temperature of the panel.
