Question

b) How much voltage can be developed and how much electricity can
be produced by one typical solar cell when exposed to the Sun ?​

Answer 1

Explanation:

Normally a single solar cell can produce upto 0.5 or 0.6 volts of voltage. A typical solar panel will comprise several solar cells, considering an example of a solar panel with dimensions of 25 by 54 inches, it normally contains around 36 solar cells and they can produce around 18 volts. The electricity depends on the load connected to the cell. If load is less, less current will be required and hence more margin in electricity

Answer 2

Production of Solar Cell

Explanation:

• Depends greatly on the cell (size, type etc), but a ballpark figure would be around 0.5 V for a typical, run of the mill Si solar cell
• Don’t confuse cells with panels though. Panels (also known as modules) are made from many cells that connected together in series and in parallel in order to reach the desired voltage and current
• 0.5V and 20% off 1000W/$m^{2}$ so a 100×100mm solar cell will deliver 0.01×0.1×1000=2W at 4A and 0.5V
• To be noted every degree C of temperature raised decreases efficiency with 0.5% Sounds not much but a temperature increased of 50C is not uncommon that is a 25% energy loss
