This paper investigates the energy performances of a hybrid system composed of a phase change materials-ventilated Trombe wall (PCMs-VTW) and a photovoltaic/thermal panel integrated with phase change material (PV/T-PCM). Equivalent overall output energy (QE) was proposed for energy performance evaluation regarding different energy forms, diversified conversions and hybrid thermal storages. This study focuses on parameters’ optimization of the PV/T-PCM system and parameters in the PCMs-VTW are kept optimal. Based on the experimentally validated numerical modelling, nine trial experiments have been conducted following Taguchi L9 (34) standard orthogonal array. The higher the better concept was implemented and the optimal combination of operating parameters was thereafter identified by using signal-to-noise (S/N) ratio and Analysis of Variance (ANOVA) method. The results show that QE is highly dependent on the mass flow rate, followed by the diameter of active cooling water pipe. However, the inlet cooling water temperature and the thickness of PCM have limited influence on QE. The optimal combination of each factor was identified as B3A3C2D1 (mass flow rate of 1 kg/s, diameter of water pipe of 0.6 m, inlet cooling water temperature of 15 °C and the thickness of PCM of 20 mm) with the highest QE of 20,700 kWh.

The production of electricity based on the conversion of the sunlight by photocells crystalline silicon is the most way using on technological and industrial plan. As a consequence, the development of the applications of energy production requires cells with high efficiency and low cost. We propose two models using either one or two exponentials allowing to simulate the characteristic current-voltage of a solar cell. The goal of our work is to present a comparative study between the model theoretical and experimental aiming at the improvement of the solar cell efficiency. We also determine the parameters of the solar cell from the current-voltage curve. Additionally, we provide a justification for using the two exponential models for improving the cell efficiency. The model with two exponential allowing to investigate the phenomena of recombination in zone of diffusion and space charge in the areas quasi-neutrals of the transmitter and the base. This study underlines the insufficiency of the model to exponential generally used by showing that it leads to the design of the ideal solar cells whereas structures characterized by a factor of quality greater outcome with high efficiency.

“…Owing to the dwindling fossil fuel supplies and the environmental consequences of their usage and the rising greenhouse gas emissions that have warmed the earth, discovering a new source of renewable, efficient and biocompatible energy is a problem confronting scientists and researchers today [1]. Attention to alternative energy sources such as solar energy, wind, hydro and tides, and biomass from fuel cells and hydrogen is of great interest in industrial and science communities today [2]. Solar energy, the world's biggest energy source, as a renewable energy source, inexpensive and free emissions, has a special role in energy supply.…”

Nanotechnology can help to address the existing efficiency hurdles and greatly increase the generation and storage of solar energy. A variety of physical processes have been established at the nanoscale that can improve the processing and transmission of solar energy. The application of nanotechnology in solar cells has opened the path to the development of a new generation of high-performance products. When competition for clean energy options is growing, a variety of potential approaches have been discussed in order to expand the prospects. New principles have been explored in the area of solar cell generation, multi-generation, spectrum modulation, thermo-photoelectric cells, hot carrier, the middle band, and many other techniques. Nanoparticles and nanostructures have been shown to enhance the absorption of light, increase the conversion of light to energy, and have improved thermal storage and transport.
