Summary of Photocell Research Characteristics

What are the basic characteristics of a photocell?

The basic characteristics of the photocell were tested and analysed through experiments by an optical control experimental platform, such as short circuit current, open circuit voltage, illumination characteristic, volt ampere characteristic, load characteristic, and spectral characteristic.

What is a photocell?

A photocell is a resistor that changes resistance depending on the amount of light incident on it. You might find these chapters and articles relevant to this topic. Ian Sinclair, in Passive Components for Circuit Design, 2001 A photocell is a light-to-electrical transducer, and there are many different types available.

How does the efficiency of a photocell differ from a real photocell?

and the efficiency is Observe that depends only on the spectral distribution and on the of the semiconductor. It completely ignores the manner in which the device operates. Unlike the efficiency of real photocells, does not depend on the level of illumination.

Why do photocells need a small series resistance?

Under such highly concentrated conditions and hence the existence of elevated current densities, the cells are required to have a sufficiently small series resistance so as to maintain an appropriately high fill factor; otherwise, photocells would suffer further undesired efficiency losses.

How does a photocell lens work?

The lens in this photocell experiment is placed at a distance of twice its focal length from both the light source and the photocell. This allows the same-sized light source to be focused onto the plane of the collector, keeping the amount of light incident on the collector as small as possible.

Are photocells responsive to the environment?

S. Esteban, in Consciousness Transitions, 2007 The capability to be responsive to the environment, i.e., to produce accurate reports is quite usual in simple animals and even in non-conscious entities. Photocells, for instance, readily report the amount of environmental light, a report which could be equalled to simple and unconscious reflexes.
