Practice Technical Speech

I thought I did an OK job on the practice technical. My slides were pretty good but I thought my topic was a little complicated (how solar cells work) and I should have simplified it more for the audience. I spent a lot of time explaining the chemistry of P[ositive] and N[egative] junctions which definitely confused some of the audience. In retrospect I probably should have spent more time talking about the basic principles of how PV cells work. A better approach would have been to talk about the basic function of PV cells, then mention the implications of improving the efficiency of these cells. Because solar energy is a vast and abundant source of renewable energy, improving the efficiency of solar cells would mean more sunlight could be converted into energy, thus making solar energy more competitive with non-renewable sources like fossil fuels. In terms of my presentation skills, I spoke a little fast and looked back at my slides a little too often. Luckily this is only the practice speech so I have time to make corrections before the next presentation. I liked how immediately following every practice speech, everyone received both negative and positive criticism. One finds out what worked and what didn't which was very helpful. I especially enjoyed the part when each of us met with another peer and redid our speeches based on the feedback. In my case, for example Adeboye reminded me not to gesticulate so much with my hands. He helped me by grabbing by hand and didn’t let it move.
