Question

A panel consists of (top to bottom) a 3-mm-thick ceria-doped glass (k = 1.4 W/m ), a 0.1-mm thick optical grade a very thin layer of within which solar energy is converted to electrical energy, a 0.1-mm thick solder layer and a 2-mm thick aluminum nitride The solar to electrical conversion efficiency within the silicon layer n decreases with increasing silicon temperature and is described by the expression where a = 0.553 and b = 0.001 K-1. The temperature T is expressed in Kelvins over the range 300 K Ts 525 K. Of the solar G = 700 W/m2, 7% is reflected from the top surface of the glass, 10% is absorbed at the top surface of the glass, and 83% is transmitted to and absorbed within the silicon layer. Part of the solar irradiation absorbed in the silicon is converted to thermal energy, and the remainder is converted to electrical energy. The glass has an of and the bottom, as well as the sides of the panel are insulted. Determine the electric power P Produced y an L = 1 wide solar panel for conditions characterized h = 35 W/m2 K and T = = 20 degree C.
