“…As such the solar cell most commonly found on domestic rooftops is still the Al-BSF cell and this is due to its simple design and comparatively high PCE. [118] These cells usually cost 0.21 $/W but since 2018 they are slowly being displaced by the PERC design on industrial production lines. Figure 3a summarizes the development of silicon photovoltaic technology from 2010 to 2020 with the associated cost and global annual production.…”

All other nanotube conformations (0° < θ < 30°) are referred to as being chiral. In this 1D system, circumferential electron confinement results in SWCNTs that are either metallic (m) or semiconducting (s) and the innate ability of small changes in diameter to impart large changes in the spectral position (size) of absorption maxima (bandgap) of the SWCNTs. [1a,2] For each chiral species these maxima appear as sets of discrete excitonic transitions (S 11 , S 22 , S 33 …etc.) in the infrared, visible, and ultraviolet and the ability to tune them with structure has made SWCNTs one of the most intensively studied nanomaterials of the past two decades. [3] SWCNTs meet all of the requirements for next generation technology to become flexible and potentially made entirely from carbon to aid disposal at the end of the product life-cycle. Applications for SWCNTs can be found across all fields of science including photonics, [4] telecommunications, [5] batteries, [6] fuel cells, [7] high frequency transistors, [8] biosensors, [9] novel memory devices, [10] molecular contacts, [11] and cancer research. [12] In particular, their chirality dependent bandgap, chemical stability, conductivity, and hole selectivity have made them attractive for new generation solar cells and light sensitive elements. [13] For example, there are 200 species in the dia meter range of 0.6-2 nm, which have first (S 11) and second (S 22) optical transitions ranging from 2.57 eV (visible) to 0.5 eV (near-infrared) and these already cover a majority of the solar spectrum (400-2000 nm), Figure 1d. [14] Being solutionprocessable and fiber-shaped, CNTs can easily be integrated into different types of solar cells with distinct functions. For example, as a photoactive layer in organic solar cell, a transparent electrode in silicon and perovskite solar cells or as counter electrode in dye-sensitized solar cells. [15] However, despite their promise, the number of real-world applications for SWCNTs in the photovoltaics (PV) industry continue to remain limited. The reasons for this are manifold and include the comparatively lower power conversion efficiency (PCE) and device area of SWCNT-based technologies, which drive simple cost-benefit arguments to retool existing production lines, ongoing challenges to orientate and control the structure of CNT films in a scalable manner, spurious health concerns associated with the use of CNTs [16] and importantly, the fact that it is still not possible to selectively synthesize SWCNTs of arbitrarily defined chirality. Most synthesis methods produce a 2:1 mixture of many semiconducting and metallic chiral types and even the CoMoCAT synthesis process, [17] which is well known to be highly enriched in small diameter (6,5), still contains at least 15 other chiral species in low concentration. Research efforts to achieve chiral specific growth are ongoing The use of carbon nanotubes (CNTs) in photovoltaics could have significant ramifications on the commercial solar cell market. Three interrelated research directions within t...

Background: Recent advancements in solar power generation technology have paved the way for a vast number of photovoltaic (PV) systems integration into the grid network. The global installed capacity of rooftop PV systems has already surpassed a 50 GW mark in 2020, while the total installed capacity of all types of PV systems is reaching beyond 500 GW. The influx of distributed PV-generators must be equipped with sophisticated control to ensure grid stability, especially during grid faults. A devastating grid outage may occur if the grid-tied PV inverters are not equipped with the "fault-ride-through" mechanism. Many countries have already enforced a mandatory grid code which includes a low-voltage-ride through requirements for PV-generators. Aim and Objective: This paper reviews the design of a rooftop PV inverters in the light of low-voltage-ride-through requirements.Materials and Methods: For the implementation of low-voltage-ride-through (LVRT), the design of low-voltage-sag detection, grid-synchronization, filterselection, and power-controllers are examined through simulations and literature survey. LVRT implementation issues are highlighted with an emphasis on the current controller performance during grid sags.Results and Discussion: From the review and analysis conducted in this study, this paper concludes that ensuring a stable DC-link and appropriate control-reference-signals during the grid faults are the keys to the LVRT implementation. Conclusion:In addition to robust power control, an autonomous PV generator should promptly detect the grid conditions and fulfils the ancillary services

“…Maximum Power Point Tracking (MPPT) is designed to gain the maximum power and the PV system is somehow dependent on the temperature and irradiance for generation of current [10][11][12][13][14]. In recent years, researchers introduced various maximum power point tracking (MPPT) techniques [15,16]. There exist a difference as to convergence speed, flexibility, and intricacy to deliver optimum performance under steady-state oscillations [17,18].…”

The presented work in this paper deals with various step sizes used in incremental conductance (INC) related to the maximum power point tracking (MPPT) technique. In the solar photovoltaic system, the variable step size selection method for INC is proposed and compared. The MATLAB/Simulink and hardware setup are used for assessing and analyzing step size methods. The variable step size (DVS), fixed step size (DFS) are comprehensively studied and compared. This DVS method is having a lower ON delay time () as 148 msec as regard to 164 msec in the DFS method. On the other hand, the lowest peak-peak oscillations in load current as 0.04 amp for DVS as compared to 0.5A for the DFS method, lower peak current as 1.96A for DVS as compare to 2.37A for the DFS method. In this way, the performance of the DVS method is found superior as it is analyzed and compared with the DFS algorithm.
