The conversion process of solar radiation into electricity occurs in an open environment, under various climatic factors and temperature variations. Therefore, the effectiveness of silicon solar cells (SC) under such conditions can be said, bearing in mind the cheapness of the technology for the production of solar cells, the use of cheap materials, durability, stability and stability of their ...

Among the various organic photovoltaic devices, the conjugated polymer/fullerene approach has drawn the most research interest. The performance of these types of solar cells is greatly determined by the nanoscale morphology of the two components (donor/acceptor) and the molecular orientation/crystallinity in the photoactive layer. A vertically bicontinuous and interdigitized heterojunction betw...

introduction electrical performance of solar cells decreases with increasing cell temperature, basically because of growth of the internal charge carrier recombination rates, caused by increased carrier concentrations. hybrid photovoltaic/thermal (pvt) systems produce electrical and thermal energy simultaneously. pvt solar collectors convert the heat generated in the solar cells to low temperat...

Recently, Djurovic and Pâquet (1996) claimed to have found an oscillation with a period of about 5.5 years in several solar and solar-terrestrial parameters, in particular in solar activity as indicated by sunspot numbers. Since the temporal evolution of solar activity and solar-terrestrial environment is of great interest in many fields, we have examined their claim in detail. We show here tha...

Global energy consumption is on the rise and is projected to double by 2050, compared with worldwide energy consumption rates in 2001.1 Sustainable energy production based on the direct conversion of energy radiated from the sun into heat or electricity is expected to gain importance, as it may be the only renewable source capable of generating sufficient energy to meet the long-term worldwide ...

Motivation Policies to promote solar photovoltaic (PV) adoption have been gaining momentum throughout the world, as concerns over global climate change and national security externalities continue to grow. In the US: 30% solar energy federal investment tax credit. Yet we understand very little about the process of diffusion of this technology.

This paper presents a method of modeling and simulation of photovoltaic arrays in MATLAB® /Simulink® using solar cell block from SimElectronics® library. The method is used to determine the characteristic of a particular photovoltaic cell panel and to study the influence of different values of solar radiation at different temperatures concerning performance of photovoltaic cells. This model it ...

rticle as: R. Kap en.2011.11.002 Abstract Nanopillar photovoltaics present significant potential for fabrication of high-efficiency, low-cost solar cells. The advantages over planar cells, including wider materials choice, device geometries, and enhanced optical and electronic properties have been studied in detail over the past decade. Specifically, the 3-D geometry enables optimization of car...
