Energy extraction characteristic study of solar photovoltaic cells and modules

Power Performance Analysis of PV Module with DC to DC Buck Converter

“…When the photovoltaic cell absorbs solar irradiations from the sun, these irradiations provide the electrons of P-type semi-conductor and the holes of N-type semi-conductor with more energy via the photons that hit them frequently. The particles, when charged with energy exceeding the band gap, can overcome the electric field of the depletion zone and can move each to the other side [6]. ISSN: 2456-7108 Available online at Journals.aijr.in Finally, the positive and negative charges accrued in the P type N-type semi-conductors, respectively, as a result of potential difference created at the ends of the PV cell as shown in figure 2.…”

Comparative study of maximum power point tracking control strategies for solar PV systems

“…Two of these extrinsic effects include: 1) current leaks proportional to the terminal voltage of a solar cell characterized by a parallel resistance R p and 2) losses of semiconductor itself and of the metal contacts with the semiconductor characterized by a series resistance R s (Fig. 2) [19]. ,…”

“…where I L is proportional to the sunlight illumination intensity, V d is the p-n junction diode voltage, V c represents the terminal voltage of the solar cell, m is the diode ideality factor (1 for an ideal diode), the diode reverse saturation current I 0 depends on temperature, q is the elementary charge, k is the Boltzmann's constant, and T is the absolute temperature [19]. If all the cells are identical and function under the same conditions of illumination and temperature, then, the current I a and terminal voltage V a produced by the solar array are a p c a s c c…”

“…First, without consideration of temperature impact by the irradiance levels, the short-circuit current of a solar cell is directly proportional to the irradiance intensity over a wide operating range [6,19]. Assume that S stands for the ratio of the present solar irradiation over the nominal irradiation of 1000W/m 2 and the short-circuit current of the solar cell at 1000W/m 2 is defined by I L1 .…”
