Full transcript

1. 0:06hello everyone
2. 0:07a very warm welcome from edu supplement
3. 0:10today we are here for another tutorial
4. 0:14on scaps 1d simulation program
5. 0:18in this video i will show you how you
6. 0:21can
7. 0:21vary the material parameters or
8. 0:24different properties of the structure
9. 0:27and get results from it to get the best
10. 0:30out of it
11. 0:31it will be convenient if you see our
12. 0:34previous video
13. 0:36which is scaps 1d tutorial a first look
14. 0:40beginner's guide
15. 0:41because it will cover the structural
16. 0:43ideas
17. 0:44and the basic ideas scaps 1d tutorial
18. 0:48okay let's start so today what i'm going
19. 0:51to show you
20. 0:52is how you can vary the thickness of the
21. 0:55absorber layer
22. 0:56of this simple peripheral sky solar cell
23. 0:59that
24. 1:00we discussed in the previous video and
25. 1:03get
26. 1:03the all solar cell parameters that means
27. 1:06open circuit voltage short circuit
28. 1:08current field factor
29. 1:09and efficiency for different thickness
30. 1:13in a single run rather by running it
31. 1:16multiple times
32. 1:18so after uh getting the data you can
33. 1:21plot
34. 1:21them and or you can and analyze them
35. 1:25and you can expect to have such kind of
36. 1:29result
37. 1:29that is the result shown here that is
38. 1:32here
39. 1:33this is the thickness and this is open
40. 1:36circuit voltage
41. 1:37thickness short circuit current then
42. 1:39thickness
43. 1:40field factor and thickness efficiency
44. 1:43so let's begin our simulation
45. 1:49so first you need to load the structure
46. 1:52that we have already done so this is our
47. 1:55structure
48. 1:56and this is the structure we worked in
49. 1:58the previous video
50. 2:00so today our target is to change the
51. 2:02thickness
52. 2:03of the absorber layer what is purpose
53. 2:06cut layer here
54. 2:08what we can do we can manually change
55. 2:10the thickness
56. 2:11of this layer and take the data but it
57. 2:13will be very tedious isn't it
58. 2:16so caps gives us the opportunity to vary
59. 2:19these
60. 2:19parameters in a single run so today we
61. 2:22will
62. 2:24learn how to do that so for doing this
63. 2:28what you have to do is that you need to
64. 2:32go to
65. 2:32that setup then you need
66. 2:36to press add and there here you will get
67. 2:40all the layers and interfaces
68. 2:43associated with your structure that has
69. 2:45been loaded
70. 2:46or are taken in scaps
71. 2:49here our target layer is pair of skype
72. 2:52layer
73. 2:53and in peripheral skype layer you will
74. 2:56get
75. 2:56all the material parameters
76. 2:59associated with this perovskite layer
77. 3:02and uh today
78. 3:03our target material parameter should be
79. 3:06thickness
80. 3:07please carefully note that here the
81. 3:09thickness is in micrometer
82. 3:11so you need to give the variation data
83. 3:15according to this unit so our today our
84. 3:18target
85. 3:18is to vary the material parameters from
86. 3:21100 nanometer
87. 3:23to 1500 nanometer so
88. 3:26today if we want to change it from 100
89. 3:29nanometer in micrometer that should be
90. 3:310.1
91. 3:32micrometer and if we want to end our
92. 3:35simulation
93. 3:36at 1500 nanometer so it should be
94. 3:391.5 micrometer now comes
95. 3:43important steps that is how what should
96. 3:45be the
97. 3:46interval or of the change that is
98. 3:49in which interval you wanna take the
99. 3:52data
100. 3:52here today we wanna take the data at
101. 3:55hundred nanometer interval
102. 3:57so from hundred nanometer to 1500
103. 4:00nanometer
104. 4:01if you give 100 nanometer interval then
105. 4:04there should be 15 points
106. 4:06so here you cannot give interval rather
107. 4:08you can give how many steps
108. 4:11you want to consider between this start
109. 4:13and end
110. 4:15so here we wanna work with the linear
111. 4:18scale
112. 4:18uh but when you need to work with log
113. 4:22scale i will show you in some other
114. 4:24video
115. 4:24uh the same it goes for custom list when
116. 4:27you need to use custom list and how to
117. 4:30use custom list i will show you in some
118. 4:32other video
119. 4:34so these are the parameters so let me
120. 4:36refresh again so first you will go
121. 4:38add then you will select the layer and
122. 4:40in
123. 4:41that layer or interface will select you
124. 4:44will select the
125. 4:45proper parameter that you want you want
126. 4:47to vary and then you will set the
127. 4:50starting point then the end point and
128. 4:53the interval will be set
129. 4:55by the steps so go to okay
130. 4:58now we need to uh set up the simulation
131. 5:01environment we give
132. 5:02we need to give light to the solar cell
133. 5:05then
134. 5:06today we are interested only for typhi
135. 5:09characteristic of the solar cell
136. 5:11then let's give the starting value of
137. 5:13the voltage as zero
138. 5:15the end value is around two uh please
139. 5:18note that
140. 5:18why we are giving two is discussed in
141. 5:21our previous video
142. 5:22and we want to stop our simulation
143. 5:25at voc so now
144. 5:29what we will do is that we will
145. 5:32do the batch calculation so we will
146. 5:34start our batch calculation that is
147. 5:36caps will change the thickness of the
148. 5:40peripheral sky
149. 5:41layer and give us the data but please
150. 5:43keep
151. 5:44a very careful notion here because there
152. 5:48will be some
153. 5:49issues that you may find and get
154. 5:51confused
155. 5:52so let's start the batch calculation
156. 5:58oops the calculation didn't work
157. 6:01it may happen when you are varying data
158. 6:04there are cert
159. 6:05for certain values the simulation may
160. 6:07not convert because it is a numerical
161. 6:09process and it is very much prone
162. 6:12not to converge so for such kind of
163. 6:14situation you don't need to get
164. 6:16panic rather what you need to do is that
165. 6:19you just ignore it
166. 6:20and see if if this becomes
167. 6:23um so it if it's resolved in the further
168. 6:28variations so here for 100 nanometer the
169. 6:31simulation didn't work
170. 6:34so press ok that means you are you're
171. 6:36ignoring it
172. 6:38so for now we are 200 nanometer
173. 6:41again the simulation isn't working so
174. 6:44it's little bit concerning
175. 6:46so let's see what happens when we ignore
176. 6:48it
177. 6:49so let's ignore it now 300 nanometer
178. 6:53it's working 400 nanometer
179. 6:56working 500 nanometer working
180. 7:00600 700
181. 7:06800 900
182. 7:121 micrometer that is thousand
183. 7:15eleven hundred twelve hundred
184. 7:20thirteen hundred fourteen hundred
185. 7:25and last but not the least fifteen
186. 7:28hundred
187. 7:29well so it didn't work for the initial
188. 7:32initial values that is for two values
189. 7:34but
190. 7:35finally we got result from 300 nanometer
191. 7:38thickness to 1500 nanometer thickness
192. 7:42so let's see how the results came so
193. 7:45here we are interested for iv
194. 7:46characteristic
195. 7:47so let's go to iv characteristic yes so
196. 7:50these are my data
197. 7:53so now where we can find the data so
198. 7:55total 15 simulations has been done
199. 7:58but yes we didn't get uh first
200. 8:01and the second so out of 15 simulations
201. 8:03we have got from
202. 8:04three to fifteen that is total two uh 13
203. 8:07simulations
204. 8:09so to get this data you
205. 8:12need to press show so
206. 8:15to get the data you need to press show
207. 8:17so it will show all the
208. 8:19simulation data it has extracted for
209. 8:22this iv characteristic
210. 8:24so you just can extract this data
211. 8:27in some other video maybe i will show
212. 8:29you how you can extract data in a very
213. 8:32efficient way
214. 8:33but not today so after extracting all
215. 8:37these data
216. 8:38you will have this this table
217. 8:41so here is thickness for every thickness
218. 8:44you are having
219. 8:45open circuit voltage short circuit
220. 8:47current fill factor
221. 8:49and efficiency now with this data you
222. 8:52can do further analysis
223. 8:54like you can take them to any data
224. 8:56related software
225. 8:57and plot them or do uh some
226. 9:00uh further analysis for your solar cell
227. 9:03or characterize
228. 9:05your solar cell in a different way or
229. 9:07optimize your
230. 9:08solar cell in some other video i will
231. 9:11show you
232. 9:11how you can read these data
233. 9:14in different kinds of data related
234. 9:17software like one of them what i
235. 9:19use mostly is matlab and i will show you
236. 9:23how you can read data in matlab
237. 9:25and then plot it so that
238. 9:28is all about today's video that we have
239. 9:31learned today
240. 9:32how you can do batch simulation and
241. 9:36you can have data by varying
242. 9:39thickness of any layer of
243. 9:42your solar cell but you can do it by
244. 9:44varying
245. 9:45all other parameters in the same way
246. 9:50the next video i will show you how you
247. 9:53can work with different kinds of
248. 9:55bulk defects and different kinds of
249. 9:57interface defects and how you can
250. 10:00vary them so thank you very much
