a b s t r a c tThe high conversion efficiency of perovskite solar cells has opened a potential market for solar cells based on low cost manufacturing techniques which could change the photovoltaic (PV) production road map. Although the 9% efficient 10 cm x 10 cm perovskite mini module has been reported, in depth analysis of the longevity of perovskite modules is required before being introduced to the market. Apart from the impressive demonstrated conversion efficiencies, these cells need to be tested under real climatic conditions in order to understand the integrity of their performance. This article briefly outlines significant spectral dependence at selected locations with varying parameters such as air mass, aerosol optical depth and precipitable water. Perovskite solar cells have shown significant dependence on the incident spectrum due to their strong absorption in the visible region. The influences of spectral variations on the performance of perovskite solar cells were studied under different atmospheric conditions. The demonstrated spectral losses by the perovskite solar cells in different climatic conditions are vital for the perovskite solar cell community to further improve their stability.

“…Of course, wind falling on the back side of passively cooled HCPV modules improves heat dissipation and decreases T c , which increases the module's efficiency. Another effect of wind is originating temperature differences between the solar cells in an HCPV module depending on its direction and the orientation of the module [29,30].…”

High-concentrator photovoltaic (HCPV) modules incorporate solar cells, optical devices, cooling mechanisms, and other elements in an assembly to provide the functions required to concentrate sunlight and obtain electricity. The variety of designs for configuring HCPV modules is introduced in this chapter. Thermal management, an important aspect to be considered in the design of these modules, is discussed, as are the possibilities and innovations for implementing cooling mechanisms. The behavior of HCPV modules is complex because of the different interdependent elements and involved processes and because of the changing operating conditions in the field. The experimental analysis of available modules has motivated progress in understanding this complex behavior. The influence of different atmospheric parameters on such behavior is analyzed in this chapter. In addition, existing models for the electrical characterization of HCPV modules are reviewed. Many of these models have been recently developed and are intended for a more accurate simulation of the behavior, for easier implementation, or for meeting specific needs of the HCPV industry. The availability of reliable models to predict the energy harvested by HCPV is important to promote this photovoltaic technology.

“…Ideally, these monitor cells offer the same spectral response as the subcells in the MJ cell of the HCPV module or system under study. This approach has been used to define spectral matching ratio [10] and the Z spectral parameter, which can be used as spectral indexes for the electrical characterization of HCPV systems [19,42]. • Ground-based measurements of atmospheric parameters.…”

Actual and forecast high-concentrator photovoltaic (HCPV) systems efficiencies may provide a scenario where HCPV represents a potential alternative to flat PV technology. The present status of HCPV efficiencies will be studied, and, on this basis, future trends regarding HCPV cells, modules, and systems efficiencies will be forecast. It will be shown that HCPV technology represents a real alternative to the current PV systems. Guidelines and normalized documents are needed to assess the overall performance of HCPV systems and to provide a general assessment of the potential of HCPV technology. The International Standard IEC 61724 publication, Photovoltaic System Performance Monitoring-Guidelines for Measurement Data Exchange and Analysis, will be highlighted. Because these guidelines are specially addressed to flat-PV technology, some suggestions, especially those adapted to the particularities of HCPV systems on both monitored and derived parameters, will be covered. Moreover, different indices of performance and losses that intend to provide comparisons between different HCPV installations will be offered adapted to the HCPV idiosyncrasy. These comparisons may be extremely useful when it comes to optimizing HCPV installation technology.
