Introduction

The LEOI-36 Experimental System for Photocell Characterization is designed to provide students with a thorough understanding of the fundamental characteristics and primary parameters of a Silicon photocell. This system emphasizes hands-on learning and encourages students to design and build optical and electrical configurations to conduct a variety of experiments. By using this system, students can gain essential skills for characterizing and optimizing the performance of photocells under different conditions.

Photocells, also known as photoelectric cells or solar cells, are devices that convert light energy into electrical energy. They are widely used in solar power applications and photo-sensing technologies. Understanding their behavior under various light conditions and electrical configurations is key to optimizing their performance and making them suitable for different applications.

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.
