“…Therefore, interconnection schemes were investigated aiming for higher packaging factors in the dense array. The investigated options are front contacted solar cells, 176 back contacted cells (metal wrap around 177 or metal wrap through 178 ), monolithic interconnected modules (MIMs), [179][180][181] and interconnection by shingling cells. 182 In Fig.…”

Concentrator photovoltaics (CPV) is a special high efficiency system technology in the world of PV-technologies. The idea of CPV is to use optical light concentrators to increase the incident power on solar cells. The solar cell area is comparatively tiny, thus saving expensive semiconductor materials and allowing the use of more sophisticated and more costly multi-junction solar cells. The highest CPV module efficiency achieved is 38.9%. This CPV module uses four-junction III-Vbased solar cells. Moreover, mini-modules have already achieved an efficiency of 43.4%. The interaction between optics, cells, and layout of the module and tracker determines the overall field performance. Today, some utility scale CPV plants are installed. The CPV technology allows for many technical solutions for system designs and for optimizing performance while maintaining the economics. This paper will review the achievements and discuss the challenges for the CPV module technology and its components. We discuss the different components and the most important effects regarding the module design. Furthermore, we present the module designs that have shown the highest efficiencies.

“…However, still some issues concerning the metal-semiconductor contact and tunnel junction breakdown were detected in these devices. Loeckenhoff solved these problems [89] by changing the metallization from Ni/AuGe/Ni to Pd/Ge and improving the growth technique of the tunnel junction layers. Besides, a back surface Ti/Au reflector was incorporated to improve the heat management of the device.…”

The optimization of the selection of heliostat aim points in a solar power tower plant with the objective of an increased overall efficiency represents a NP-hard optimization problem of high dimension. This paper presents a universal procedure for the purpose of aim point optimization based on the ant colony optimization metaheuristic that uses the principles of swarm intelligence. The applicability of the developed aim point optimization procedure to central receiver systems is demonstrated on a test case, for which the electrical power of a concentrated photovoltaic (CPV) receiver is maximized for a selected operating point. The example of a CPV receiver was chosen due to its nonlinear and nonmonotonous dependency of efficiency and flux density. It is shown that the optimization result is very close to the theoretical maximum.
