Hello, I have a question on simulating microgrid solar cell for photovoltaic performance (ex. Jsc, Voc, etc.)<\/div>\n
I questioned a similar topic before. But I think it is more related to CHARGE than FDTD so I start a new post. <\/div>\n
Here’s the link to my previous post:  <\/div>\n
x-y metalgrid of solar cell in CHARGE (ansys.com)<\/a><\/div>\n
 <\/div>\n
In my question, the microgrid solar cell represents a planar silicon solar cell that has a grid metal electrode and the spacing of the grid is micro-scale (max 500 μm).<\/div>\n
My final goal is to get the photovoltaic performance of the microgrid solar cell.<\/div>\n
 <\/div>\n
It is not difficult to calculate optical generation rate of 500 μm microgrid solar cells. Using the feature ‘periods’ in the analysis group, I can obtain the optical generation rate, which is very long on the x-axis (500 μm) but narrow on the y-axis (0.01 μm).<\/div>\n
<\/a><\/div>\n
<\/a><\/div>\n
Then, this optical generation rate file is imported to CHARGE. In the CHARGE, I set the dimension of CHARGE simulation region to 2D Y-Normal and it makes the width of y from 0.001 μm to 500 μm by using the feature ‘norm length’.<\/div>\n
Originally, the memory requirements of this microgrid solar cell simulation are approximately 30,000 GB even though the mesh accuracy is 1.. But, the memory requirements can be significantly reduced with ‘period’ in FDTD and ‘norm length’ in CHARGE.<\/div>\n
 <\/div>\n
However, the point of this simulation is the collection of carriers into the microgrid electrode and the analysis of the electrical properties of the solar cells. If I use the ‘norm length’ in the CHARGE, I can’t set the electrode in the x-axis because it is 2D-Y Normal. Microgrid solar cell in the 2D-Y Normal has only a parallel metal grid and the carrier is collected only 2-ways (in the x-axis).  <\/div>\n
<\/a><\/div>\n
 <\/div>\n
How can I design the metal grid solar cells that collect carriers in four ways? If I set the dimension of the CHARGE simulation to 3D, optical generation data should also be based on the 3D.<\/div>\n
And, as I said previously, it requires 30,000 GB of memory to run the FDTD simulation even though the mesh accuracy is 1.<\/div>\n
 <\/div>\n
I don’t know all the features of CHARGE and lumerical script, so I guess the solution can be from CHARGE that I didn’t know.<\/div>\n","protected":false},"template":"","class_list":["post-346949","topic","type-topic","status-closed","hentry","topic-tag-charge"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["27993","18532"],"_bbp_author_ip":["23.206.193.146"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["236"],"_bbp_topic_status":["unanswered"],"_edit_lock":["1706517216:229976"],"_bbp_topic_id":["346949"],"_bbp_forum_id":["27833"],"_bbp_engagement":["18532","27993"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["347313"],"_bbp_last_active_id":["347313"],"_bbp_last_active_time":["2024-01-30 14:40:36"]},"test":"handonseas-harvard-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/346949","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":2,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/346949\/revisions"}],"predecessor-version":[{"id":346951,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/346949\/revisions\/346951"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=346949"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
