Hello. I have been trying to set up a Lumerical FDTD simulation for running structure optimization and sweep of a solar cell. For this, I have declared a structure group of solar cell layers with the layer thickness value as input user-defined parameters. I have also tried to set the FDTD and monitor dimension based on the user-defined solar cell structure group properties. For the later part, I have added the following code in the model setup script.<\/p>\n

select(“PSC_pin”);<\/em><\/span>
set(“h_HTL_1”, HTL_zspan); #sweep variable <\/span><\/em><\/span>
set(“h_ABS”, PSC_zspan); #sweep variable <\/span><\/em><\/span>
runsetup;<\/em><\/span><\/p>\n

select(“PSC_pin::BC”);<\/em><\/span>
PSC_zbottom = get(“z min”);<\/em><\/span>
select(“PSC_pin::TCO”);<\/em><\/span>
PSC_ztop = get(“z max”);<\/em><\/span><\/p>\n

offset_src = 200e-9;<\/em><\/span>
src_z = PSC_ztop+offset_src;<\/em><\/span>
select(“source”);<\/em><\/span>
set(“z”, src_z);<\/em><\/span><\/p>\n

FDTD_offset = 100e-9;<\/em><\/span>
FDTD_zmax = src_z+FDTD_offset;<\/em><\/span>
FDTD_zmin = PSC_zbottom-FDTD_offset;<\/em><\/span>
select(“FDTD”);<\/em><\/span>
set(“z min”, FDTD_zmin);<\/em><\/span>
set(“z max”, FDTD_zmax);<\/em><\/span>
select(“PSC_pin::HTL_1”);<\/em><\/span>
solar_ztop = get(“z max”);<\/em><\/span><\/p>\n

select(“PSC_pin::ETL_1”);<\/em><\/span>
solar_zbottom = get(“z min”);<\/em><\/span>
solar_z = (solar_ztop + solar_zbottom)\/2;<\/em><\/span>
solar_zspan = solar_ztop – solar_zbottom;<\/em><\/span><\/p>\n

select(“solar_generation”);<\/em><\/span>
set(“z”, solar_z);<\/em><\/span>
set(“z span”, solar_zspan);<\/em><\/span>
runsetup;<\/em><\/span><\/p>\n

 <\/p>\n

When I ran the sweep, the structure, FDTD domain, and source position were updated in the newly created .fsp files but the monitor dimension remained the same. Outside of sweep, I tried changing the thickness parameters from the model’s setup variable section. But for the monitor to be updated properly, I had to click the ‘test’ twice.<\/p>\n

After clicking “test” first time, I had the message that the structure group script had run. After clicking “test” second time, I had the message that the solar generation analysis group script had run. <\/p>\n

What should I do to run the sweep using this setup properly?
