This experiment was done to find out how the efficiency of the solar cell will change at different temperature conditions.
Procedure preview:
For this experiment, the independent variable is the operating temperature of the solar cell. The dependent variable is the power output from the solar cell. This is determined by measuring the voltage and current. The constants (control variables) are the resistor, lighting conditions and the solar cell type. The solar cells are assembled as shown in figure 1. The first solar cell is placed on a metal plate. The metal plate will become hot and increase the operating temperature of the solar cell The second solar cell is assembled using 4 pieces of 50mm screws, 4 nuts and 1 .....
