1. Calculate the filling factor of a photovoltaic cell whose dimensions are 15 cm per side, and a thickness of 200 µm of which 99% correspond to the “p” type absorbent layer and where there is also a amount of 13500 electrons. The thickness of the space loading region junction is 200 nm.
The cell is subjected to standard test conditions, which produces every second a generation of electron-hollow pairs of 2.0x10¹⁹ cm⁻³ and which translates into an increase in its density of 4.0x10¹³ cm⁻³. The efficiency of the cell is measured at 20%.
Consider that the cell is in thermal equilibrium (300K), its prohibited band is 1.12 eV and that the mobility coefficients are 1360 cm² / Vs for electrons and 450 cm² / Vs for holes.

Q =10, 15 m3/s and the slope will be S = 15 cm/km and the side slope, so Z =1. For a trapezoidal channel, given the flow rate, Q, the slope, S, the side slope, Z, n = 0.014, the channel is to be designed to have minimum cost. You are required to: a) What is the value of Q and S? b) What is the ratio of bottom width, b, to flow depth, y? c) Design and draw the...

1.) The femur of an elephant is about 90 cm long and 15 cm in diameter. This is a scaling problem. The largest dinosaur probably weighed about 10 times as much as a large elephant. In this problem we will be discussing scaling. For reference, areas scale as length squared(A=L^2 for a square and A=3.14*r^2 for a circle) and volume scales as length cubed. To describe the size of a dinosaur's femur compared to that of an elephant's, the dinosaur's...
