2 Experimental part

2.1 The experimental equipment

Figure 9.8 Electric sheme

Diagram of the experimental setup photocell is shown in Figure 9.8.

μA is a microammeter to measure the photocurrent; R₁ is potentiometer to control the voltage U₁ at the photocell; V₁ is voltmeter to measure the voltage U₁; V₂ is voltmeter to measure the voltage of the lamp L.

2.2 Performance of the experiment

Task 1. Definition of the current-voltage characteristics of solar cell and its sensitivity. 1. Turn on the scheme and set a specific voltage incandescent bulbs (eg, U₂ = 200V). This voltage is kept constant throughout the experiment.
