A 1 cm2 silicon solar cell has a saturation current of 10A and is illuminated with sunlight yielding a short-circuit photocurren
Yuki888 [10]

Answer:

The answer is "13% and 83%"

Explanation:

The highest power is generated for:

\to \frac{dP}{dV_a}=0= I_s(e^{\frac{V_m}{V_t}} -1)-I_{Ph} +\frac{V_m}{V_t} I_s e^{\frac{V_m}{V_t}}

 Where voltage, V_m, was its calculated maximum power wattage.  This same following transcend national stable coins the power output:

\to V_m=V_t \ In \frac{1+\frac{I_{ph}}{I_s}}{1+\frac{V_{m}}{V_t}}

The accompanying consecutive values of V_m are done utilizing iteration and an initial value of 0.5 V:

\to V_m = 0.5,\  0.542,\  0.540 \ V

Efficacy is equivalent to:

\eta = |\frac{V_{m} I_{m}}{p_{in}}| =\frac{0.54 \times 0.024}{0.1}=1.3\%

Currently, I_m was calculated with the formula of voltage V_m (4.6.1) as well as the sun is presumed to produce  100 \frac{mW}{cm^2} of power.

The fulfillment factor is equal to:

fill factor= \frac{V_{m} I_{m}}{V_{oc}I_{sc}}= \frac{0.54 \times 0.024}{0.62 \times 0.025}=83\%

where open circuit tension of equations (4.6.1) and I = 0. is calculated. The current is equal to the total current of the photo.

Liquid nitrogen boils at 77.2 k. what is this temperature in degrees celsius
Ratling [72]
<span>77.2 k is -195.95 C
       
To convert from Kelvin to Celsius, you simply subtract 273.15 from the temperature. So the expression becomes c = 77.2 - 273.15 = -195.95</span>
