florian galusha's come up with a new method of extracting even more power from sunlight. but. what we've done instead of using normal silicon solar cells which have a maximum laboratory efficiency of 26 to 27 percent is to use somewhat more exotic cells their maximum lab efficiency is over 47 percent but they're expensive and above his expensive solar super cells a panel of lenses each of which focuses sunlight on an individual cell throughout the day that boosts efficiency to 29 percent in real life conditions. the main challenge is making sure the light actually hits the cell if it doesn't and it won't produce any energy at all. and drop them in it you know. in gaelic celebratory we get my idea of how it works he uses a model to show how the lenses function each lens in the top panel focuses the sunlight on an exactly defined. radius covering a super cell. because those cells are tiny barely one millimeter across. and we use about $10000.00 cells per square meter and each has to have a high degree of tolerance. but now it's time for the engineers to put the lab behind them.
