Have you ever wondered how to make a solar cell in a research lab? We have put together a video for an in depth peek into the Solar Power Lab and shows how we make our record breaking solar cells. We describe the process from the bare silicon wafer to the final solar cell for our heterojunction cells, which have a record high open circuit voltage over 750 mV. Most cells made in indutry have a much lower voltage at 640-650 mV and use a process called phosphorus diffusion with rear aluminum back surface field (we have a pilot line for that too). Thanks to Dr Andre Augusto for putting this together, our final year high school intern Zoe Ellison for providing the narration and all the students who work in the lab making better solar cells..
