Consider a typical I-V and P-V curve of a solar module as shown in the figure below.a) For any set of irradiance and temperature conditions, the PV module always has the \(P_{mpp} \gt V_{oc} \times I_{sc}\).b) The rest of the conditions remaining the same, if the irradiance falling on the PV module uniformly increases such that the new P-V curve has an MPP at \(P_{mpp}'\), then \(P_{mpp}' \gt P_{mpp}\).c) The rest of the conditions remaining the same, if the irradiance falling on the PV module uniformly increases such that the new P-V curve has an MPP at \(P_{mpp}'\), then \(P_{mpp}' \lt P_{mpp}\).d) For V=\(V_{mpp}\), \(\frac{dP}{dV} = 0\).Which of the above statements are true?

A. a) and b)
B. d) only
C. b) and d)
D. c) and d)

Consider a PV module with the following parameters as measured at STC (Standard Testing Conditions):\(V_{oc}\) = 50 V;\(I_{sc}\) = 4.5 A;\(I_{mpp}\) = 4 A;\(V_{mpp}\) = 40 V;Efficiency = 18%.Suppose that under normal operation at STC conditions, the module is not connected to an MPPT device, and is instead directly connected to a purely resistive, variable load 'R'. The load R can be tuned to give a resistance between 0 to \(1\;k\Omega\). What value of resistance will you keep the load at, if you wish to derive maximum power from the PV module under STC conditions?

A. R = \(11.11\;\Omega\).
B. R = \(10\;\Omega\).
C. R = \(100\;\Omega\).
D. Irrespective of the value R takes, the module can never be made to deliver maximum power under ST

Imagine you want to fabricate a triple junction solar cell that consists of three quantum dot-based solar cells (see figure below). Each cell consists of quantum dots of a certain diameter: 4nm, 6nm and 10nm. In which order (from top to bottom) would you put these cells in order to absorb the most part of the solar spectrum?

A. First, the 4 nm cell on the top. Then, the 6 nm cell. Finally, the 10 nm cell on the bottom.
B. First, the 6 nm cell on the top. Then, the 10 nm cell. Finally, the 4 nm cell on the bottom.
C. First, the 10 nm cell on the top. Then, the 6 nm cell. Finally, the 4 nm cell on the bottom.
D. First, the 10 nm cell on the top. Then, the 4 nm cell. Finally, the 6 nm cell on the bottom.
