The present study introduces an analytical approach for predicting net power for highconcentrating photovoltaic systems (HCPV). Wind speed, surface radiation, and size of the backplate, which acts as a heat spreader, were found to be of high impact in increasing solar cell efficiency and maximum produced power. The efficiency increased by 5% as the wind shifted from light air (0.5 m/s) to fresh breeze (10 m/s). Also, it increased by 1.64% as the aluminium backplate shifted from a shiny (ɛ = 0) to a dark (ɛ = 1) surface. Furthermore, increasing heat-spreader length or wind velocity caused a logarithmic increase in solar cell efficiency. On the other hand, both parameters caused an exponential increase in consumed power due to the operation of a tracking system. Thus, optimal values of heat-spreader length at which maximum net power is produced exist. A case study based on the annual average values of the hourly-basis meteorological data for the period 2015 to 2018 for two cities in Saudi Arabia was conducted. It was found that the size of the heat spreader could be reduced by 36% for concentration ratio up to 2000 while concurrently increasing the net power by 2.6% and 6% for the systems built in Riyadh and Dammam, respectively.

“…In this technology, referring to concentrated solar power (CSP), sunlight focused on optical collectors is the origin of heat that drives an electrical power generator [5,6]. To eliminate disadvantages and highlight the advantages of solar power systems, concentrated photovoltaic (CPV) as a hybrid technology has been developed [7]. In comparison to conventional PV systems, the CPV is still a young and small player in the market for solar electricity generation, with a relatively small number of research works and operating installations [2].…”

Application of LCA to Determine Environmental Impact of Concentrated Photovoltaic Solar Panels—State-of-the-Art

Photovoltaic systems represent a leading part of the market in the renewable energies sector. Contemporary technology offers possibilities to improve systems converting sun energy, especially for the efficiency of modules. The paper focuses on current concentrated photovoltaic (CPV) technologies, presenting data for solar cells and modules working under lab conditions as well as in a real environment. In this paper, we consider up-to-date solutions for two types of concentrating photovoltaic systems: high-concentration photovoltaics (HCPV) and low-concentration photovoltaics (LCPV). The current status of CPV solar modules was complemented by the preliminary results of new hybrid photovoltaic technology achieving records in efficiency. Compared to traditional Si-PV panels, CPV modules achieve greater conversion efficiency as a result of the concentrator optics applied. Specific CPV technologies were described in terms of efficiency, new approaches of a multijunction solar cell, a tracking system, and durability. The results of the analysis prove intensive development in the field of CPV modules and the potential of achieving record system efficiency. The paper also presents methods for the determination of the environmental impact of CPV during the entire life cycle by life cycle assessment (LCA) analysis and possible waste management scenarios. Environmental performance is generally assessed based on standard indicators, such as energy payback time, CO2 footprint, or GHG emission.

High-Performance Luminescent Solar Concentrators Based on Poly(Cyclohexylmethacrylate) (PCHMA) Films

et al. 2020

In this study, we report on the use of poly(cyclohexylmethacrylate) (PCHMA) as an alternative to the commonly used poly(methylmethacrylate) (PMMA) for the design of efficient luminescent solar concentrators (LSCs). PCHMA was selected due to its less polar nature with respect to PMMA, a characteristic that was reported to be beneficial in promoting the fluorophore dispersibility in the matrix, thus maximizing the efficiency of LSCs also at high doping. In this sense, LSC thin films based on PCHMA and containing different contents of Lumogen F Red 305 (LR, 0.2–1.8 wt%) demonstrated optical efficiencies (ηopt) comprising between 9.5% and 10.0%, i.e., about 0.5–1% higher than those collected from the LR/PMMA systems. The higher LR/polymer interactions occurred using the PCHMA matrix maximized the solar harvesting characteristics of the fluorophore and limited the influence of the adverse dissipative phenomena on the fluorophore quantum efficiency. These effects were also reflected by varying the LSC film thickness and reaching maximum ηopt of about 11.5% in the case of PCHMA films of about 30 µm.
