“…Note also that the top side of the triangular receiver is able to absorb both beam and diffuse radiation, whereas PV layers can only convert the concentrated beam radiation. In summary, the system considered in this work is basically the same as the one shown in references [24,28] with two main differences: (i) there is no covering glass; (ii) the PV layer is based on InGaP/InGaAs/Ge triple-junction solar cells [15]. These two modifications increase significantly the electrical efficiency of the system with respect to the values reported in [24,28].…”

“…Therefore, the overall energy balance on a control volume that included the entire triangular receiver is: (15) Among the terms on the right hand side, the first one is the useful thermal energy, the second one is the electrical power produced and all the remaining terms are losses. As discussed in the following section, this energy balance is dominated by the radiative terms, as the convection losses are low due to the small receiver area, typical of concentrating solar collectors.…”

“…Conversely, for high concentration ratios, the PVT operating temperature and the corresponding inefficiencies may significantly increase (for silicon cells, the voltage drops to zero at 270 °C) [4]. Therefore, the use of CPVT may be improved adopting novel PV materials, such as multi-junction solar cells which can approach a nominal efficiency of 40% [14,15]. The adoption of such materials in CPVT may lead to a system operating up to 240 °C at reasonable conversion efficiency (slightly lower than 20%) [14].…”

This paper presents a design procedure and a simulation model of a novel concentrating PVT collector. The layout of the PVT system under investigation was derived from a prototype recently presented in literature and commercially available. The prototype consisted in a parabolic trough concentrator and a linear triangular receiver. In that prototype, the bottom surfaces of the receiver are equipped with mono-crystalline silicon cells whereas the top surface is covered by an absorbing surface. The aperture area of the parabola was covered by a glass in order to improve the thermal efficiency of the system. In the modified version of the collector considered in this paper, two changes are implemented: the cover glass was eliminated and the mono-crystalline silicon cells were replaced by triple-junction cells. In order to analyze PVT performance, a detailed mathematical model was implemented. This model is based on zero-dimensional energy balances. The simulation model calculates the temperatures of the main components of the system and the main energy flows Results showed that the performance of the system is excellent even when the fluid temperature is very high (>100 °C). Conversely, both electrical and thermal efficiencies dramatically decrease when the incident beam radiation decreases.

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.

Corresponding author: nc13005@student.miyazaki-u.ac.jpAbstract. Concentrator photovoltaic (CPV) technology has the potential to decrease the cost of systems in the near future by using less expensive optical elements in the system which replace the receiving surface aperture and concentrate the sunlight onto small solar cells. One of the main concerns of CPV is the need for high precision tracking system and the relation to the acceptance angle. In this paper, we proposed a CPV module with concentration ratio larger than 100 times and wide acceptance angle. An optical simulation for the module with S-TIM2 glass as a lens material was conducted to estimate the optical performance of the module. Thermal and electrical simulation was also conducted using COMSOL Multiphysics and SPICE respectively to evaluate the working temperature and electrical characteristics of the multijunction solar cell under concentration conditions.
