Single (1T)- and dual (2T)-axis tracking systems adapt the orientation of PV modules to track the sun''s position, minimizing sunlight angle incidence on PV modules. A combination of bifacial modules with single-axis trackers produces the cheapest electricity, by significantly boosting energy production (35% more than conventional systems).
The literature provides some examples to prove this fact in the field of nano photovoltaics i.e. quantum dot-based thin film solar PV cells, QDSSC (quantum dot-sensitized solar PV cells), hybrid bulk-heterojunction solar PV cells and CdSe nanoparticles based QDSSC having an efficiency of about 4.54% [15], [16], [17].

Working Principle of Photovoltaic Cells. A photovoltaic cell essentially consists of a large planar p–n junction, i.e., a region of contact between layers of n- and p-doped semiconductor material, where both layers are electrically contacted (see below). The junction extends over the entire active area of the device.
2.1 Solar photovoltaic systems. Solar energy is used in two different ways: one through the solar thermal route using solar collectors, heaters, dryers, etc., and the other through the solar electricity route using SPV, as shown in Fig. 1.A SPV system consists of arrays and combinations of PV panels, a charge controller for direct current (DC) and alternating current

Similarly, to photovoltaic cells, the absorbance of the plant leaf depends on the spectral distribution of the incident light.

Enhancing Solar Energy Harvesting Efficiency: A Dual-Axis Solar Tracking System Abstract: The photovoltaic effect has permanently transformed the landscape of renewable sources by making it possible to convert solar energy into useable power.
This paper presents an optimisation methodology that takes into account the most important design variables of single-axis photovoltaic plants, including irregular land shape, size and configuration of the mounting system, row spacing, and operating periods (for backtracking mode, limited range of motion, and normal tracking mode).
This consists of the following steps: (i) Inter-row spacing design; (ii) Determination of operating periods of the P V system; (iii) Optimal number of solar trackers; and (iv) Determination of the effective annual incident energy on photovoltaic modules. A flowchart outlining the proposed methodology is shown in Fig. 2.
The optimal layout of single-axis solar trackers in large-scale PV plants. A detailed analysis of the design of the inter-row spacing and operating periods. The optimal layout of the mounting systems increases the amount of energy by 91%. Also has the best levelised cost of energy efficiency, 1.09.
The design of the row spacing always avoids shading between the photovoltaic modules, contributing to the increase of generated energy, and reducing the appearance of hot spots. A comprehensive study of the operating periods has been carried out, classifying them broadly into backtracking mode, limited range of motion and normal tracking mode.
The larger the width of the mounting system, the larger the total area of the photovoltaic field. The cost of the mounting system is strongly influenced by the type of configuration. The larger its width, the higher the cost of the mounting system, because the size of the profiles of the purlins and pillars increases due to the wind loads.
For this purpose, codes and standards have been used for the structural analysis of these mounting systems. In the structural analysis, the weight of the structure, the weight of the photovoltaic modules, snow loads, wind loads and their combinations have been calculated.
