Photonic devices such as solar cells and photodetectors that produce electricity play a vital role in our daily life for applications such as fibre optic communication systems, process control, and also in defence related applications. Today, two-dimensional perovskites that belong to the class of emerging materials show promising energy applications. 2D perovskites have been investigated for their exceptional properties such as high optical absorption coefficients, structural diversity and tuneable bandgaps which allow their application as active light absorbing materials to develop solar cells and photodetectors. Carbon-based nanomaterials have also found applications as transparent electrodes, charge acceptors and photosensitive layers in solar cells and photodetectors due to properties such as excellent electrical conductivity, high optical transparency, high surface area and remarkable mechanical strength. There has been growing interest in research on devices using these materials to improve their feasibility, ease of production and performance. With the growing urgency of switching to alternate sources of energy and increasing demands for highly accurate and fast sensors, the development and application of such novel materials are essential. Hence, the current state of understanding of these materials and their applications in the field of solar cells and photodetectors are summarized in this review article.

“…The influence of solar energy on the power sectors has increased its demand in the recent decades due to its abundant availability. A further help in terms of low cost production activities of photovoltaic/solar cells [1,2] is increasing its presence as a widespread one in the present scenario. These solar cells convert photon energy into electrical energy using photovoltaic effect and are made up of p-n semiconductor junctions.…”

“…One of the major advantages of photovoltaic cells is that they are highly modular and by proper scaling, they can be expected to provide adequate power for various loads. Literature studies [2][3][4][5][6][7][8][9][10] have proven the interest taken by researchers on photovoltaic cells, especially in developing models using various softwares. The accuracy in simulation depends principally on the modeling, which includes the estimation of values used for I-V as well as P-V characteristics.…”

In this paper, an analysis has been done on the effect of varying physical and environmental factors on the I-V (current voltage characteristics) of a photovoltaic cell using Matlab-Simulink. A standalone model has been created based on the mathematical relations between various parameters in photovoltaic cells made up of a single diode, a series resistance, and a shunt resistance. To validate the developed model, the values from I-V characteristics of this model have been compared with the experimental results. In addition, simulations have been done for I-V characteristics for different temperature and resistance values. The results obtained are analyzed and presented in this paper.

“…Fill factor is defined as the ratio of the maximum power from the solar cell to the product of Open Circuit Voltage V oc and Short-Circuit Current I sc . The typical fill factor for commercial solar cells is usually 0.70 [27].Classical solar cells require thicker materials to perform good optical absorption but loose carrier collection efficiency due to the higher minority carrier length [28]. …”

Reducing cost and improving conversion efficiency are the main tasks in order to make photovoltaic energy competitive and able to substitute traditional fossil energies.Nanotechnology seems to be the way by which photovoltaics can be developed, whether in inorganic or organic solar cells. Wide-bandgap nanostructured materials (nanomaterials) prepared from II-VI and III-V elements are attracting an increased attention for their potential applications in emerging energy. They can be prepared in different geometric shapes, including nanowires (NWs), nanobelts, nanosprings, nanocombs, and nanopagodas. Variations in the atom arrangements in order to minimize the electrostatic energy originated from the ionic charge on the polar surface are responsible for a wide range of nanostructures.This book chapter will focus on contribution of nanomaterials in solar cell technology advancement. KeywordsNanomaterials; Solar cells; Organic; Inorganic; Nanopillars; Nanowires; Nanobelts; Nanorods; Photocarrier collection IntroductionSolar cells have known a big expansion these last years due to the voluntary move to cleaner energies like photovoltaics. Table 1 summarizes the chronological evolution of photovoltaic cells with their main characteristics. After solid-state physics has shown its limits by reaching the maximum possible conversion efficiency for silicon, CdTe, and CuInSe 2, the highest conversion efficiency was obtained for triple-junction compound InGaP/GaAs/InGaAs solar cell with 37.9 % [6]. Chemistry seems to be another way by which an increase of the solar cell conversion efficiency is possible. Nanomaterials made by chemical ways present high opportunity in efficiency enhancement by increasing light trapping and photocarrier collection without additional cost in solar cell fabrication.The physical and chemical properties change from the bulk material to the nanomaterial. As an example, the melting point is lowest for the nanomaterial compared to its bulk one. This can be due to the high surface-to-volume ratio of atoms in a nanoparticle [7].The main nanomaterial physical property is the large surface-to-volume ratio [6] due to different forms created; nanowires [8,9], nanopillars [10,11], nanocones [12], quantum dots [13].It has been shown that light trapping is due to the increase of the photon path inside nanostructures [14][15][16] which enhance the electron-hole pair creation probability. Quantum dots (QDs) have the particularity to have a size-dependent bandgap [13,17,18] so it can be adjusted to fit the maximum solar spectrum. Classical Solar CellsBefore introducing the added value of nanomaterials in solar cells, a brief comeback should be presented to understand the work mechanism of solar cells.A solar cell is an electronic device, a P/N junction in its basic form, which has the ability to convert sunlight into electricity. This phenomenon was discovered by Edmond Becquerel in 1839 and is called the photovoltaic effect [19].Not all materials can be solar cell components. Because the main feature sho...
