FLATCON® CPV module with 36.7% efficiency equipped with four‐junction solar cells

Abstract

In this paper we present the application of high efficiency four-junction solar cells using SOITEC bonding technology under a Fresnel lens optic and in a FLATCON W -type CPV module. We demonstrate very high performance. The measurement of a sub-module, consisting of a four-junction solar cell adjusted under a single Fresnel lens, showed an efficiency of 38.9%. An 829.6 cm 2 sized FLATCON W -type CPV module yielded in an efficiency of 35.0% and 36.7% at CSOC and CSTC, respectively. Thus, both, the sub-module and the CPV module showed record values, which prove the usefulness of high efficiency four-junction solar cells in CPV applications.

Solar energy for future world: - A review

“…A new record of 36.7% is reported for an 830 cm 2 photovoltaic module. Using a four cell stack [146]. This module was fabricated and measured at Fraunhofer Institute for Solar Energy Systems (FHG-ISE).…”

III-V Multi-junction solar cells and concentrating photovoltaic (CPV) systems

“…The modules are positioned on a two-axis tracker, which assures that the solar cells are in the focus of the lenses throughout the day (Figure 6, right). Fraunhofer ISE recently demonstrated a CPV module efficiency of 36.7% at Concentrator Standard Test Conditions (CSTC) [61].…”

Development and outdoor characterization of a hybrid bifacial HCPV module

“…In the following, we present the design, development, and characterization steps followed to upscale and transform our hybrid monofacial CPV submodule into an enhanced hybrid bifacial HCPV module ( A =1088 cm 2 , C geo =321x). It is important to note that we followed the manufacturing processes of the FLATCON® module , a proven CPV technology capable of converting up to 36.7% of DNI .…”
