LEOI-36 Experimental System for Photocell Characterization

LEOI-36 Experimental System for Photocell Characterization

Features

  • Compact and vertical structure with low stray light impact

  • 4 photocells (monosilicon and polysilicon)

  • Pitch angle adjustable for different illumination angle of light








Introduction

This experimental system is designed to help understand the fundamental characteristics and primary parameters of a Silicon photocell. Students are required to design and build optical and electrical configurations to conduct various experiments so that their hands-on skills can be enhanced. This system can be used to conduct the following experiments with Silicon photocells:

 

1. Short-circuit current, open-circuit voltage, max output power, optimal load and fill factor under light illumination.

2. V-I characterization of photocells in the absence of light illumination with bias voltage applied.

3. Short-circuit current versus open-circuit voltage of photocells under different light intensities.

4. Open-circuit voltage versus short-circuit current of photocells under different illumination angles.

5. Serial and parallel characteristics of photocells.
