China Wholesale Diode laser Factory – LPT-5 Experimental System for Photocell Characterization – Labor

Features

• Vertical structure is adopted in design to avoid mutual distracting from transverse  light  source .

• In can descent lamp is used as  light  source  to  ensure  easy maintenance  and  replacement . The light i n tensity i s adjustable in 5 gear s.

• Equipped wit h 2 monocrystalline silicon solar cells and 2 polycrystalline in  sillicon solar cells .

• 5V Maximum open -circuit voltage, 80 m A maximum short -circuit current , 10K adjustable o ad resistance and 0 -5 V adjustable on - load voltage .

• the solar cells are pitch-adjustable to study the influence on the solar cell’s absorbing power under different lighting angles.

Experiments

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.
