I Have a Research Support System

"Is it a problem with the filter? The X-ray filter rate is too high?" Xu Qiu asked.

"Filters, filter magnification..." Meng Ren muttered for a while, and then analyzed:

"The signal strength is just about 10 times worse, and each stop of the filter is also reduced to 10% of the previous stop. This is probably the reason."

He typed the query code of the current filter gear into the computer, and the computer screen popped up soon:

filter 6

Prompt that the current filter gear is 6 gears.

Meng Ren keyed in the code again, adjusted the filter position to 5 levels, and then checked the signal strength.

This time the signal strength value changed to 32156.

This data is within the normal range.

"The problem is solved," Meng Ren admired, "Brother, you can't hide it."

Chen Wanqing and Han Jiaying also looked at Xu Qiu curiously.

Xu Qiu smiled and said nothing.

...

Afterwards, there were no other problems with Meng Ren's operation, and his condition gradually improved, and he was not as nervous as he was at the beginning.

After cutting the light, Meng Ren explained the precautions, left a contact information, and left.

The personnel inside their light sources have their own laboratories and offices. The on-duty work at the online station is considered a voluntary job, and they are scheduled on a weekly basis.

It is a bit similar to the teaching task of professors in colleges and universities, who need to take one or two classes every week, and light source researchers also have the task of assisting user testing.

Almost an hour and a half passed, and the teacher still didn't come.

Fortunately, I chose to start debugging directly, otherwise, if people came over in the afternoon, the experiment would be delayed for a long time.

The three began to divide the work.

Similar to the light source test last time, Chen Wanqing was in charge of operating the computer, and Xu Qiu took Han Jiaying to change samples.

In the test cabin, there were only Xu Qiu and Han Jiaying.

"Brother, you can complete the light cutting operation by yourself just now."

"you guess."

"..."

It seems that the school girl's intuition is relatively sharp, but it is impossible for him to admit it.

The first few samples were all based on the Xu Qiu system. From the sample signal, the data is still good.

When changing samples one time, he heard Han Jiaying's stomach growl.

Looking at the time, it was almost half past twelve noon, Xu Qiu said:

"Hungry? Going to eat?"

"Hmm..." Han Jiaying whispered in embarrassment:

"I didn't eat much for breakfast."

"It's okay, I'm a little hungry too." Xu Qiu said:

"It's just that there is no commercial street here, and eating is a problem. I guess there is a cafeteria inside the light source."

"It should be, let's ask Senior Sister."

"Okay, pack this sample up, don't test it first."

Back in the next office, Xu Qiu said:

"Let's go have lunch, is there a canteen near the light source?"

"Of course there is. In such a big research institute, the employees inside also have to eat," Chen Wanqing said:

"However, employees have employee cards and can order food at will. Users like us can only buy meal coupons and set meals."

The three packed up and left the main building.

Chen Wanqing walked ahead and led the way.

The cafeteria is still a bit far from the main building, about one kilometer away.

Coming to the canteen, it has only one floor, but there is another building next to it, which seems to be able to provide accommodation.

Following the signs, the three of them came to a place similar to the front desk of a hotel.

Xu Qiu asked the clerk:

"Are the meal coupons bought here?"

"Yes."

"Buy three."

"A total of 30 yuan."

After scanning the QR code to pay, the clerk handed over three meal coupons.

On a thin piece of paper, there are three large characters "dining coupon" marked in the center, and an oval red stamp is also stamped on it. The small characters below it say that it is dedicated to the light source of the city, and it was printed three years ago.

If you don't look carefully, it looks like the kind of certificate placed at the bottom of the food box.

The canteen is not big, and there are not many people dining, which may be due to the coincidence of the peak dining period.

The price is quite cheap. One big meat, one small meat, one vegetarian dish, one bowl of soup, and one bowl of rice only cost 10 yuan, which should be subsidized like the canteens of colleges and universities.

The dishes have been served in small bowls in advance, and there are only two or three choices for each, and there is not much room for choice.

Auntie Dacai took Xu Qiu's meal coupons and inserted the three meal coupons on an iron stick.

The three of them packed their meals and found a table to sit down.

"It tastes good, but it's a bit cold." Xu Qiu said after taking a bite of the smoked fish.

"It's late, the canteen here should open after eleven o'clock." Chen Wanqing said.

Han Jiaying nodded in agreement, then took a sip of the soup:

"The soup is hot, you can drink some soup first."

...

After lunch, return to the BL14B1 line station.

After a short break, the three began to discuss the next division of labor.

Considering that Han Jiaying has basically learned how to change samples, she will be responsible for this.

Chen Wanqing was still in charge of operating the computer, while Xu Qiu was in charge of processing the test data in real time.

Although some information can be seen from the raw data, for example, the crystallization performance of the Xu Qiu system is very good, but it is still not intuitive enough.

Moreover, after data processing, if it is found that a sample is not tested well, it can be re-tested on the spot.

Otherwise, in case there is a problem with a key data and needs to be retested, it will have to wait for the next light source machine, which may take more than a month.

Xu Qiu first processed the data of 1# and 2# samples, which are based on the system with the best photoelectric performance.

Respectively, PBFBT4T-2OD single component film, and its blend film with PCBM acceptor.

Data processing is complete.

The background of sample 1# is clean and bright blue, and the sample signal mainly appears on the horizontal and vertical axes.

There are three signals on the vertical axis, that is, crystal signals perpendicular to the substrate surface, corresponding to the crystal plane indices (100), (200) and (300), and the positions are about the negative power of 0.27, 0.54 and 0.81 angstroms.

There is only one signal on the horizontal axis, that is, the crystal signal on the substrate surface, corresponding to the crystal plane index (010), and the position is about the negative power of 1.60 angstroms.

The 2# sample also has all the sample signals of the 1# sample, but it is weaker than the 1# sample.

In addition, a ring-shaped signal belonging to PCBM appeared, which was approximately at the negative power of 1.40 angstroms.

This shows that the PBFBT4T-2OD material is a standard face-on structure, and charge carriers are easily transported in the vertical direction. Such materials are very suitable for solar photovoltaic devices.

On the contrary, if the (100) signal appears on the horizontal axis and the (010) signal appears on the vertical axis, it corresponds to an edge-on structure, and charge carriers are easily transported in the horizontal direction. Such materials are suitable for Organic Field Effect Transistor OLED.

"Perfect."

Seeing such a result, Xu Qiu was determined.

Different characterization test results can be mutually confirmed, which finally explains the reason for the high performance of the device.

The last piece of the jigsaw puzzle of this work just fits perfectly, with almost no flaws.
