“…PhCs are designed in one, two, and three-dimensional structures, whose two-dimensional structure has been considered by researchers due to its greater applications and fabrication simplicity. Research groups designed a variety of structures using two-dimensional PhCs such as optical filters [1-5], logic gates [6][7][8], encoders and decoders [9][10][11][12], comparators [13,14], multiplexers and demultiplexers [15,16], adders and subtractors [17][18][19][20][21][22][23][24], registers [25,26], memories [27][28][29], splitters [30][31][32], analog-to-digital converters [33][34][35], optical fibers [36][37][38][39][40][41][42][43], sensors [44][45][46][47][48][49][50], PhC fibers [38,…”

In this study, we propose a refractive index sensor for the simultaneous detection of cancer and diabetes based on photonic crystals (PhC). The proposed PhC composed of silicon rods in the air bed arranged in a hexagonal lattice forms the fundamental structure, and two tubes are used to place the cancerous or diabetic samples for measurement. The sensor's transmission characteristics are simulated and analyzed by solving Maxwell's electromagnetic equations using the finite-difference time-domain method for samples under study. The diagnosis of three types of cancer and diabetes is based on changing the samples' refractive index by applying the laser source centered at 1550 nm. Our results demonstrate that the proposed structure's quality factor and sensitivity can be adjusted by changing the sensor's geometry. They reveal that the transmission power is between 91% ~ 100%, depending on the sample. The sensitivity range is also between 1294 and 3080 nm/RIU. The maximum figure of merit is about 1550.11 RIU -1 with a detection range of 31×10 -6 RIU. The small biosensor area of 61.56 µm 2 makes it a suitable device for various applications in compact photonic integrated circuits.

“…Various studies have also recently reported efficiency of around 23.4% of this module. [60][61][62] An important factor that impacts the output of the solar module is the temperature coefficient. It is a measure of the decrease in output power for every 1°C rise in temperature over 25°C of the temperature a solar module receives.…”

In Pakistan, around 58% of current electricity is generated from fossil fuels and only 2.4% is generated using renewable energy (RE) resources even though country is blessed with enormous RE potential. Among other RE resources, Pakistan's geographical location offers high solar energy potential, which implies that actual potential assessment should be undertaken. This study, as such, undertakes a comprehensive assessment of solar energy potential and prospects of solar photovoltaic (PV) systems for both off-grid and gridconnected systems. This study also estimates the future available capacity of rooftop and rural off-grid solar PV capacity. Three different types of solar PV modules of the same size, that is, thin-film, premium, and standard were modeled to compare energy outputs. NREL's System Advisor Model (SAM) is used to estimate the geographical and technical potential of solar PV considering updated data and geographical information. SAM results suggest that an average of 4.5 kWh/kWp/day is obtained from an installed capacity of 1 KWp. The logistic modeling equations are further used to forecast the solar PV penetration over a period until 2090. The research investigation concludes that 2.8 × 10 6 GWh of electricity can be generated annually in Pakistan. The estimated results prove that solar PV has the potential to meet the present as well as future energy needs of Pakistan.

“…Which predicts that increasing dipole moment state will increase optical nonlinearity. In a logic way, MTTHPC is a potential competitor for finest perovskite solar cells (MAPbI 3 ) embedded with Au nanospheres that possess a band offset (3.1 eV) with conversion-efficiency 24.84% (Tabrizi et al 2021). Figures 4 and 5 show computed band offsets and electronic density of states (DOS) for MTTHPC, respectively.…”

Both theoretical and experimental studies are briefly discussed to shed lights on crystal shape, FT-IR, electronic, and non-linear opto-response (NLO) characteristics of ethyl4-(3,4-dimethoxyphenyl)-6-methyl-2-thioxo-1,2,3,4-tetrahydropyrimidine-5-carboxylate (MTTHPC). Theoretical FT_IR results are in a proper concord with recorded measurements. MTTHPC has TDM (4.78 Debye) and a doublet spins that splits original FMOs into alpha(↑, 2.44 eV) and beta(↓, 1.28 eV) offsets, respectively. MTTHPC is a potential competitor for finest perovskite solar cells (MAPbI 3 /Au-nanospheres) that possess a band offset ( 3.1 eV ) with conversion-efficiency 24.84%. MTTHPC may be the next chapter for unique avalanche photodetectors (APD). MTTHPC 1st order hyperpolarizability is 14.15 * 10 −30 esu , surpass reference urea (≈ 40 urea , urea = 0.3728 * 10 −30 esu ). Briefly, MTTHPC may be admitted as the next stage in forthcoming NLO technology.
