“…Further we subcategorize light management into (1) spectral beam splitting, which involves manipulating solar irradiation to distribute the light to more than one absorber/converter based on wavelength, and (2) spectral modification that involves changing the spectral distribution of solar irradiation using various methods such as upor down-conversion. The concept of beam splitting and the methodologies used for implementation are provided in the reviews of Imenes and Mills [2] and Mojiri et al [3]. While systems that facilitate spectral modification often add cost and complexity to standard solar converters such as solar parabolic troughs or flat plate PV for example, spectral management allows control of the proportion of solar energy that is converted into thermal, electric, or even chemical energy.…”

Due to the inherent broadband nature of the solar radiation, combined with the narrow spectral sensitivity range of direct solar to electricity devices, there is a massive opportunity to manipulate the solar spectrum to increase the functionality and efficiency of solar energy conversion devices. Spectral splitting or manipulation facilitates the efficient combination of both high-temperature solar thermal systems, which can absorb over the entire solar spectrum to create heat, and photovoltaic cells, which only convert a range of wavelengths to electricity. It has only recently been possible, with the development of nanofabrication techniques, to integrate micro-and nano-photonic structures as spectrum splitters/manipulators into solar energy conversion devices. In this paper, we summarize the recent developments in beam splitting techniques, and highlight some relevant applications including combined PV-thermal collectors and efficient algae production, and suggest paths for future development in this field.

In this work, we have analyzed the characteristic J-V of vertical multijunction (VMJ) solar cells. We offered a design of a monolithic compact solar module with cells electrically connected in series. The extracting the electrical parameters of multi-junction solar cells from characteristics data J-V which such as: J 0 , saturation current density; R s , series resistance; R sh , shunt resistance; n, ideality factor and J ph , photo current density are obtained with light concentration is given. We have developed the program code for the analysis with a nonlinear least-square method. We have found that the algorithm results in a stable convergence and the experimental results on the photo current voltage (J,V)characteristics can be reliably reproduced using the extraction electrical parameters using nonlinear least-square method. It was founded untraditional depends shunt resistance from sun concentration. We suggest some mechanism physics explaining of this phenomenon. We see when increase the concentration the efficiency η increasing. We have achieved high-voltage silicon solar modules with voltage up to 25.491 V at 500 suns.

“…After them, many studies have been carried out to explore the possibilities of exceeding this limit. Different technologies and methods were used for that purpose [2][3][4][5][6][7][8][9][10][11][12][13][14][15]. Among these approaches, we could cite tandem cells, concentrator cell, carrier multiplication, down conversion, hot carriers, etc.…”

Effect of external applied electric field on the silicon solar cell’s thermodynamic efficiency

et al. 2017

View full text Add to dashboard Cite

This paper presents a possible solution to improve the efficiency of photovoltaic solar cells. An external electric field is applied on a silicon photovoltaic solar cell, inducing band-trap ionization of charge carriers. Output current is then monitored and the thermodynamic efficiency is calculated. Results show on the one hand a significant increase in efficiency for a certain margin of applied electric field, and on the another hand the instabilities of efficiency. A simple approach is then suggested for the implementation of these results. An efficiency of 67% has been reached for an applied electric of 1586 V/ Cm.
