class jarvis.analysis.solarefficiency.solar.SolarEfficiency(formalism='slme')

Bases: object

Calculate theoretical solar-efficiency using SLME or SQ approach.

calculate_SQ(bandgap_ev, temperature=300, fr=1, plot_current_voltage=False, filename='sq.png')

Calcualte efficeincy using shockley queisser formalism.

Requires only two inputs unlike SLME. Args:

bandgap_ev: bandga in electron-volt

temperature: temperature in K

slme(material_energy_for_absorbance_data, material_absorbance_data, material_direct_allowed_gap, material_indirect_gap, thickness=5e-05, temperature=293.15, absorbance_in_inverse_centimeters=False, cut_off_absorbance_below_direct_allowed_gap=True, plot_current_voltage=False, filename='slme.png')

Calculate spectroscopic limited maximum efficiency.

Reuires more info than SQ. Args:

material_energy_for_absorbance_data: energy grid for absorbance data

material_absorbance_data: absorption coefficient in m^-1

material_direct_allowed_gap: direct bandgap in eV

material_indirect_gap: indirect bandgap in eV

thickness: thickness of the material in m

temperature: working temperature in K

absorbance_in_inverse_centimeters: whether the absorbance data is in the unit of cm^-1

cut_off_absorbance_below_direct_allowed_gap: whether to discard all absorption below bandgap

plot_current_voltage: whether to plot the current-voltage curve

Returns:

The calculated maximum efficiency.
