Excitons play a crucial role in silicon solar cells and are involved in several processes that contribute to the generation of electricity. Here are some key roles of excitons in silicon solar cells:

1. Absorption of Photons: When photons from sunlight strike the silicon material of a solar cell, they can be absorbed by silicon atoms, promoting an electron from the valence band to the conduction band. This process creates an exciton—a bound electron-hole pair.

2. Exciton Diffusion: After absorption, excitons can diffuse through the silicon material, moving towards the region of the solar cell where charge separation occurs. This diffusion process allows excitons to reach the vicinity of the p-n junction, where the separation of charges takes place.

3. Exciton Dissociation: At the p-n junction of a silicon solar cell, excitons can undergo dissociation. The electric field created by the junction separates the electron and hole of the exciton, allowing them to move freely in opposite directions as charge carriers.

4. Electron and Hole Transport: Once the exciton is dissociated, the free electron and hole can move independently within the solar cell. They are transported through the silicon material to the respective electrodes, creating an electric current that can be harnessed for external use.

5. Recombination: Excitons can also undergo recombination, where the electron and hole recombine, releasing energy in the form of light or heat. Recombination is undesirable in solar cells as it reduces the overall efficiency of the device.

To enhance the efficiency of silicon solar cells, various strategies are employed to minimize exciton recombination and improve exciton dissociation and charge carrier transport. These include the use of anti-reflection coatings, surface passivation techniques, and optimization of the device structure.

Overall, excitons play a vital role in the absorption and conversion of sunlight into electrical energy in silicon solar cells. Understanding and controlling exciton dynamics are essential for improving the performance of solar cells and advancing the field of photovoltaics.

Answer:

Voltmeter reactance = 2π × 50 × 0.7 = 220ΩImpedance of voltmeter = 3000 + j220 = 3008Ω When the voltmeter range is doubled its impedance has also to be doubled in order to have the same current for full-scale deflection. If R is the required series resistance then 3000 + R2 + 2202 = 2 × 30082 ∴ R = 3012Ω When used on d.c. supply if the voltmeter reads 200 V the actual applied d.c. voltage would be = 200 × Total A.C. Impedance/total d.c. resistance = 200 × 2 × 3008/3000 + 3012 = 200 × 6016 × 6012 = 200.134V.

The correct answer is d. Built-up roofing (BUR),It consists of layers of overlapping roof felt with each layer set in a mopping of hot tar of asphalt.

Built-up roofing is a durable and reliable option containing asphalt roofs. It is a traditional roofing system that has been used for many decades. BUR consists of multiple layers of roof felt or roofing fabric, typically made of fiberglass or organic materials.

These layers are set in a mopping of hot tar or asphalt, which acts as an adhesive and creates a strong bond between the layers.The process of installing a BUR system involves alternating layers of roofing felt and hot tar.

Each layer is carefully mopped onto the roof surface, ensuring proper overlap and coverage. This layering process enhances the waterproofing capabilities of the roof, providing excellent protection against water infiltration.

The final layer of a BUR system is often topped with a layer of gravel or other surfacing material. This surfacing layer serves multiple purposes. It protects the underlying layers from UV radiation, helps to distribute the weight of foot traffic or equipment, and provides additional fire resistance.

One of the key advantages of built-up roofing is its longevity. When properly installed and maintained, a BUR system can last for several decades. It is also resistant to fire, making it a popular choice for commercial and industrial buildings.

In summary, built-up roofing is a layered roofing system that utilizes roof felt and hot tar to create a durable, watertight, and fire-resistant roof. Its proven track record and longevity make it a reliable option for flat or low-slope roofs.

In a situation where  the university's  administration wishes to use cellular manufacturing to simplify the arrangement of the social club kiosks in the main plaza. There are ten separate social club kiosks, with ESTIEM and EST having double the space.

At least 20 students will visit the kiosks, with some students visiting the same kiosk many times. What is the  minimal number of cell  necessary to fulfill demand  if each kiosk can handle three students at a time?

Now to the assuption:

What is  the solution?

because  we have been given the following :

The number of pupils is 20.

The number of kiosks is ten.

ESTIEM and EST kiosk area = 2 x (other kiosk space)

Let x be the number of needed cells.

(number of pupils) x (number of kiosk visits per student) = total number of visits

20 x 1 = 20 total number of visits

The maximum number of visits per cell is three.

Total number of visits / Maximum number of visits per cell = Minimum number of cells necessary

Minimum number of necessary cells = 20 / 3 = 7

Answer:

The right answer is "16.5 hrs".

Explanation:

Given values are:

\(x_1=2.6 \ mm\)

\(t_1=3 \ hrs\)

\(x_2=6.1 \ mm\)

As we know,

⇒ \(\frac{x^2}{Dt}=constant\)

or,

⇒ \(\frac{x_1^2}{t_1} =\frac{x_2^2}{t_2}\)

⇒ \(t_2=(\frac{x_2}{x_1})^2\times t_1\)

By putting the values, we get

       \(=(\frac{6.1}{2.6} )^2\times 3\)

       \(=5.5\times 3\)

The oxygen binding curve of hemoglobin devoid of BPG is comparable to that of myoglobin.

Option B is correct.

As an intermediate in the glycolysis process, 2,3-BPG is a naturally occurring molecule. It is a hemoglobin allosteric effector. Oxygen binding curve without 2,3-BPG In the absence of 2,3-BPG, this molecule will unbind in the center of the structure of hemoglobin. This will keep hemoglobin in its relaxed state and prevent it from rapidly changing into its tensed state.

That is, after unbinding with hemoglobin, 2,3-BPG raises hemoglobin's affinity for oxygen, causing the oxygen-binding curve to shift all the way to the left, just like myoglobin's. The T-state of deoxyhemoglobin causes the equilibrium to shift to the R-state, where the majority of hemoglobin will be bound to oxygen (i.e., have a high affinity for oxygen) and the deoxyhemoglobin will not exist for long.

For ε = 0.1, approximately 2.147 random inputs are needed for a collision. The number of inputs required for the hash functions producing outputs of lengths 128 and 160 bits using the same formula.

To determine the number of random inputs needed to achieve a specific probability of collision, we can use the birthday paradox principle. The birthday paradox states that in a group of people, the probability of two individuals having the same birthday is higher than expected due to the large number of possible pairs.

The formula to calculate the approximate number of inputs required for a given probability of collision (ε) is:

n ≈ √(2 * log(1/(1 - ε)))

Let's calculate the number of inputs needed for ε = 0.5 and ε = 0.1 for each hash function:

For a hash function producing a 64-bit output:

n ≈ √(2 * log(1/(1 - 0.5)))

n ≈ √(2 * log(2))

n ≈ √(2 * 0.693)

n ≈ √(1.386)

n ≈ 1.177

For ε = 0.5, approximately 1.177 random inputs are required to have a probability of collision.

For ε = 0.1:

n ≈ √(2 * log(1/(1 - 0.1)))

n ≈ √(2 * log(10))

n ≈ √(2 * 2.303)

n ≈ √(4.606)

n ≈ 2.147

For ε = 0.1, approximately 2.147 random inputs are needed for a collision.

Similarly, we can calculate the number of inputs required for the hash functions producing outputs of lengths 128 and 160 bits using the same formula.

Please note that these calculations provide approximate values based on the birthday paradox principle. The actual probability of collision may vary depending on the specific characteristics of the hash functions and the nature of the inputs.
