Day 10: 6/3

 Today was a pretty hectic day filled with lots of things that I learned. Firstly, I learned that I need to leave by 9:45 to get to the lab on time. 

Upon getting to the lab, I worked with John to get the perovskite scribing in place. We sanded/grinded down the aluminum of the robot plate to get a more even surface. We then looked at the heights of the robot arm and the attached razor blade to ensure that it was done properly. We made sure the height was right by using a Voltmeter (johns from 1975 lol), and seeing if there was any electrical conductivity.

John then taught me how to cut glass and we cut the 25mm x 25mm into 25x15 so we could PL map it. Felix then taught us how to use his PL mapping program and I wrote it down on my phone.

After lunch, I talked to John about our plans and we got some stuff planned out. We then worked on the scribing again and cut the 3D printed thing for some compliance.

Things I noted today:

• Need to glass encapsulate the cells and blow nitrogen into it if we life cycle it outside (perhaps 30 cells?)
• Cannot put it in a vacuum as it will mess with the Iodine
• Determine how strong is HTL vs the perovskite layer (can ask Xiaobing?)
• Ask Xiaobing to give us complete cells that has been scribed
• Determine our exact cell layout/ layer orders
• Ask Likai what thermal degradation occurs (also ask AI)
• How can we characterize the damage?
• How tall is the perovskite cell?
• How can we make a photolithographic wall?
