Say you want to power your house with solar panels. You find in a catalog 10cm10cm solar cells made of doped crystalline silicon: bandgap = 1.1eV, estimated output voltage = 0.6V, photogeneration efficiency = 70% (e.g. 30% photogenerated electron-hole pairs recombine), loss due to heat generated by photons with energy greater than the bandgap = 50.89%, cost per panel including all electronics = $36.00 You know that the intensity spectrum of the sun can be modeled as that of a 6000K blackbody radiation, normalized to 1000 W/m 2 (AM1.5). Also, knowing that your house requires on average 6000W during the 5 h of good sunshine period every day in your area at 120V. How to design a system of solar cells to power your house (e.g. how to make connections in series and/or in parallel)? How much will it cost? Will you buy this system?
