Reverse Bias in Solar Cells – Romiko Derbynew
With photocells, we need to apply a reverse bias in order to increase the effect of an internal electric field in the junction, thus causing an imbalance of drift and diffusion
Photocell
Thus the reverse bias voltage decreases switching time but reduces the sensitivity of the circuit. Figure 21.3. (Left) A photodiode. The cathode of a diode is the shorter leg, and the anode is the longer leg. Unlike the efficiency of real photocells, η ideal does not depend on the level of illumination. Again, for a black body, (14.24)
Unconscious bias
It does not mean that unconscious bias is an excuse for racism. We must all feel accountable for our actions and the things we say to our colleagues, patients and the people around us. Being more aware of what unconscious bias is and examining our own possible biases is crucial to advancing equity and fairness in our judgements and actions.

6 FAQs about [What does photocell bias mean ]
Why do photocells need a reverse bias?
With photocells, we need to apply a reverse bias in order to increase the effect of an internal electric field in the junction, thus causing an imbalance of drift and diffusion across the depletion region. For the photocell, the holes tend to enjoy staying in the p region and the electrons in the n region, reverse bias enhances this tendency.
How does a photocell work?
A photocell is a resistor that changes resistance depending on the amount of light incident on it. A photocell operates on semiconductor photoconductivity: the energy of photons hitting the semiconductor frees electrons to flow, decreasing the resistance. An example photocell is the Advanced Photonix PDV-P5002, shown in Figure 21.2.
How does a photocell change its resistance?
A photocell or photoresistor is a sensor that changes its resistance when light shines on it. The resistance generated varies depending on the light striking at his surface. A high intensity of light incident on the surface will cause a lower resistance, whereas a lower intensity of light will cause higher resistance.
What happens if a solar cell has a forward bias?
What about forward bias? In forward bias, the internal field would essentially be destroyed and the charge carriers would move very slowly and hence your solar cell would be less effective.
What is the sensitivity of a photocell?
The sensitivity of a photocell is defined as its resistance at a specific level of illumination. Since no two photocells are exactly alike, sensitivity is stated as a typical resistance value plus an allowable tolerance. Both the value of resistance and its tolerance are specified for only one light level.
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.
