“…The V oc decreases while the J increases depending on the narrowing energy band gap when the temperature of a solar cell is increased [33]. The decrease of the V oc is greater than the increase of the J, and thus the η of the solar cell decreases with the increase of the temperature [34][35][36]. As can be seen in the figure, the η of the GaInP/GaInAs/Ge TJ solar cell decreases along with the increase of temperature.…”

The photovoltaic energy is one of the most popular topics of research in the field of clean energy sources. It benefits directly from the sun, and has been accepted as a promising technology for the future. To this end, GaInP/GaInAs/Ge TJ solar cells, capable of being grown with the molecular beam epitaxy device, are designed along with tunnel junction layers. In this work, the analytical solar cell model is used for the calculation of solar cell performance. The calculation for the photo-response of the radiation spectrum of the solar cells includes an analytical solution equation in the model, including the continuity equations based on both the minority and majority carriers, the Poisson equation, and the current equation. For these calculations, Fortran programming language is used with high data sensitivity. The J, Voc, and η values of the GaInP/GaInAs/Ge TJ solar cell are calculated for the AM1.5G solar spectrum at temperatures in the range 200-450 K. The η of the solar cell at room temperature under 1 sun is calculated as 35.114%. As a result, triple or higher junction solar cell structures need to be designed in order to obtain greater efficiency.

“…Some investigators have proposed different methods to obtain the parameters of the subcells by making different assumptions and simplifications. Examples of extraction methods based on the SEM scheme can be found in the literature [46,55,59,[66][67][68] as can results from those based on the DEM scheme [59,[69][70][71]. It is important to note that these studies usually estimate the parameters at a particular set of operating conditions.…”

High Concentrator Photovoltaics

Multijunction (MJ) concentrator solar cells are primarily constructed of III-V semiconductor materials. The high solar-conversion efficiencies of these devices are dependent on precise control of growth conditions using one of several techniques such as molecular beam epitaxy, metal organic chemical vapour, or metal organic vapour-phase epitaxy deposition. The use of several junctions in an MJ tandem stack allows these devices to achieve efficiencies that are not possible for single-junction devices. Their behaviour is consequently complex, but it can be understood through an examination of the external quantum efficiency and the temperature dependence of each cell in the stack. This chapter lays out a systematic approach for understanding the spectral and temperature dependence of the overall MJ device by way of consideration of its component subcells. The efficiency of the cell as a function of temperature and concentration is described for both lattice-matched and metamorphic triple-junction (TJ) solar cells. The electrical characteristics and current-voltage curves are described from these considerations, and the performance of MJ solar cells under real operating conditions are then presented by considering a term describing the overall thermal factor and another term for the spectral factor. These terms can be understood from the background presented in the previous sections. Finally, the power output for the complete cell incorporated into a Fresnel lens based high-concentration photovoltaic system is presented for a particular geographic location using meteorological data.

“…These two material parameters J 01 and J 02 are calculated using the equations published by Reinhardt et al [27] and using a procedure presented in detail in [28]. A similar procedure to derive J 01 and J 02 was published by Nishioka et al in [29], for instance.…”

In this work, we discuss three empirical models and introduce one more detailed model named YieldOpt. All models can be used to calculate the power output and energy yield of concentrating photovoltaic (CPV) modules under different ambient conditions. The YieldOpt model combines various modeling approaches: simple model of the atmospheric radiative transfer of sunshine for the spectral irradiance, a finite element method for thermal expansion, ray tracing for the optics, and a SPICE network model for the triple-junction solar cell. YieldOpt uses a number of constant and variable input parameters, for example, the external quantum efficiency of the cells, the temperature-dependent spectral optical efficiencies of the optics, the tracking accuracy, the direct normal irradiance, the aerosol optical depth, and the temperature of the lens and the solar cell. To verify the accuracy of the models, the I-V characteristics of five CPV modules have been measured in a 10-min interval over a period of 1year in Freiburg, Germany. Four modules equipped with industrial-standard lattice-matched triple-junction solar cells and one module equipped with metamorphic triple-junction solar cells are investigated. The higher accuracy of YieldOpt compared with the three empirical models in predicting the power output of all five CPV modules during this period is demonstrated. The energy yield over a period of 1year was predicted for all five CPV modules with a maximum deviation of 5% by the three empirical models and 3% by YieldOpt
