Lab 11 Silicon Photovoltaics
supplies for this lab you will need cleaved pieces of boron doped silicon spin-on phosphorus dopent a pipetter or dropper glass etent cream cotton swabs solder wires Gallum indiia mctic and tweezers step step one applying the spin-on dopent this portion of the lab requires a spin coater and a hot plate and should be performed in a fume Hood first open the lid to the spin coater you will see a black o-ring on a vacuum Chuck that will hold your sample as it spins grab a piece of boron do silicon with your tweezers now place the Silicon piece on top of the vacuum Chuck the piece should be roughly centered on the Chuck and and must completely cover the black o-ring to ensure a good vacuum seal press the blue vacuum soft key to turn on the vacuum next open up the bottle of spin-on dopent and pipe it out a small volume of solution apply several drops of the spinon dopen to the Silicon piece the drops should completely cover the surface close the spin coater lid and press the st...
