Improved Photovoltaic Cell Calculation

Energy Range for Efficiency Improvement
- Energy range: 1.5 × 10^-19 J to 6.00 × 10^-19 J
- Collection efficiency: 97%

Absorption Coefficient
- Absorption coefficient: 82%

Calculation of IL
To calculate the light-generated current (IL) for the improved photovoltaic cell, we need to consider the improved collection efficiency and absorption coefficient. The IL is given by the following formula:
IL = q * ∫ (Φ(E) * η(E) * A(E) * dE)
Where:
- IL is the light-generated current
- q is the charge of an electron (1.6 x 10^-19 C)
- Φ(E) is the frequency of photons as a function of energy
- η(E) is the collection efficiency
- A(E) is the absorption coefficient
- dE is the energy interval
By plugging in the given values of the collection efficiency (97%) and absorption coefficient (82%), and integrating over the energy range from 1.5 × 10^-19 J to 6.00 × 10^-19 J, we can calculate the IL for this improved photovoltaic cell.
This calculation will provide us with the light-generated current for the improved photovoltaic cell, taking into account the increased collection efficiency and absorption coefficient.
