In order to get a better insight into the relationship between molecular structure and photovoltaic performance, six monoazo dye molecules containing benzoic and cinnamic acid moieties were synthesized and their photovoltaic properties were studied. Three of them have not been previously used in solar cells. Spectroscopic measurements of the investigated compounds coupled with theoretical calculations were performed. Short-circuit current density, open-circuit voltage, and fill-factor were determined.

Currently, with the disappearance of fossil energy sources, finding new alternative energy sources is very necessary such as: solar energy, wind energy, tidal energy, flow energy, ... However, these energy sources require high investment capital, large capacity, and bulky size. In circuits requiring small power sources (below 12V), it is not applicable, or only used through intermediate devices such as transformers, current transformers; Therefore, the application of energy from mechanical vibration has been proposed as an optimal measure compared to the above methods..

To this aim, ten physics-based models have been investigated to determine the cell temperature, and those models have been validated using measured PV cell temperatures by computing the Root Mean Square Error (RMSE). Then, the model with the lowest RMSE has been adopted in training a data-driven prediction model. The proposed prediction model is to use an ANN compared to the well-known benchmark model from the literature, i.e., Multiple Linear Regression (MLR).

This paper presents the preliminary analysis of ground-based measurements solar data in Umlazi, South Africa. From this analysis, data statistics and statistic models for the global horizontal irradiance (GHI), the direct horizontal irradiance (DHI) and the ultraviolet radiations (UVR) are obtained for Durban and surrounding areas. Those results can be used in the design and analysis of solar systems and can also be used as referential parameters for further assessment of solar energy potentials for those areas.

Photosynthesis is able to convert solar energy into chemical energy in the form of biomass, but the efficiency of photosynthetic solar energy conversion is low. Chlorophyll fluorescence measurements are rapid, nondestructive, and can provide a wealth of information about the efficiencies of the photosynthetic light reaction processes.

Catalyst TiO2 with N-doped, Mg-doped and N-Mg co-doped were created by impregnation method with Mg(NO3)2 (add Mg in) and mix method with urea (add N in). The XRD, SEM, DR, BET, FT-IR measurements were carried out for structural characterization of the TiO2 samples. The result performed, compared with the sample of initial TiO2-P25 particle size and specific surface area, samples of doped-catalyst changed insignificantly.

In this paper, we prepared CZTS nanoparticles by hydrothermal method and investigate the influence of hydrothermal temperature on the product. Raman scattering, X-ray diffraction, scanning electron microcopy, energy dispersive X-ray spectroscopy and diffusion reflective measurement were applied to characterize the products. The products are high quality nanocrystals of kesterite phase with uniform size which is applicable for solar absorber layer fabrication.

Among the potential renewable energies, solar photovoltaic (PV) power has recently experienced enormous utilizationin electrical power generation due to the advances of solar PV technologies. Various studies have been conducted in order to forecast solar PV power generation in different perspectives. Unfortunately, there is always a mismatch between the forecasted solar PV power data from the proposed methodologies and the measured generation data.

For retailers, success is easy to measure: it’s the ringing of the cash register. a state solar program’s marketing activities, to be effective, also must lead to an action: an application for a solar program’s financial incentive to purchase and install a solar energy system. While state solar programs are not directly “selling solar installations” to customers, nevertheless, they measure success in the form of megawatts of solar installed. therefore, the state mar- keting approaches and activities must lead the customer to the solar sale.

These days, it is impossible to think of an area of knowledge that can keep on developing without a collaboration in interdisciplinary fields. Electromotive force is a type of energy per unit of electric charge that is converted reversibly from chemical, mechanical, or other forms of energy into electrical energy by a dynamo, battery, electrochemical cells, thermoelectric devices, solar cells, transformers, and so on. The theory of electromotive Force is currently one of the most important research topics within the electrical engineering domain.

From its inception nearly 30 years ago, the optical subdiscipline now referred to as nonimaging optics, has experienced dramatic growth. The term nonimaging optics is concerned with applications where imaging formation is not important but where effective and efficient collection , concentration, transport and distribution of light energy is - i.e. solar energy conversion, signal detection, illumination optics, measurement and testing. This book will incorporate the substantial developments of the past decade in this field.
