An ideal photovoltaic cell absorbs light using a semiconductor with a bandgap equal to 1.5 eV in an AM 1.5, global tilt spectrum. (Note that in at least some of the tables one can download, the interval between wavelengths is not always a constant throughout the spectrum. Using a trapezoidal rule in a spreadsheet or the trapz function in matlab can easily take care of this.) Assume that any photon with energy greater than the bandgap is absorbed and contributes to the short circuit current. Find the short circuit current. Find the reverse saturation current using the Cuott's fit given in class, i. e. J_0 = 2.8 times 10^-11 T^3 e^BE_g/kT_e^-Eg/kT mA/cm2 where B = 0.504. Find the maximum power this cell could provide Find the maximum theoretical efficiency of the device.

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.
