“…Its mirror can be made of transparent fused silica glass, coated with a dielectric layer, functioning as a band pass filter. The high energy waves over 1.4 eV could be filtered out and routed to ultraviolent optimized solar cell [6]. The lower reflector mirror is made of silvered borosilicate as shown in Fig.…”

CSP (concentrated solar power) has been viewed as the technology that if properly developed could lead to a large scale conversion of solar energy into electricity. CSP is a type of solar energy converter that is classified as thermal converter because the output power produced is a function of the operating temperature. The main components of a CSP plant are the solar field which is made up of the heliostat arrays, the receiver tower, the heat transfer fluid, the molten salt thermal energy storage tanks and the power conversion unit, which is made up of the turbine and the generator. The main advantage of CSP is that of a cheap thermal storage (i.e., molten salt storage) which makes it possible to dispatch power at a cost comparable to the grid electricity. Simulations run with the SAM (systems advisory model) developed by NREL (National Renewable Energy Laboratory) showed that CSP is capable of delivering electricity at the cost of 17UScents per kWh for the 30-year life of the plant. The main disadvantage of CSP however, is that of low efficiency (8%-16%). There are ongoing research works to improve the efficiency of the CSP. One way to improve the efficiency is to increase the operating temperature of the system. In this paper, the authors discussed different modules of the CSP plant and suggested ways to improve on the conversion efficiencies of individual modules. Finally, an overall systems performance simulation is carried using SAM and the simulation results show that electricity can be produced using CSP at the cost of R1.05 per kWh.

“…Most of the today PV panels, with multicrystalline silicon technology, have efficiencies between 11% and 18%, while the use of mono-crystalline silicon allows to increase the conversion efficiency of about 4%. The recourse to multi-junction cells, with use of materials as Gallium Arsenide (Thilagam et al, 1998), and to concentrating technologies (Segal et al, 2004), has allowed to reach 40% of cell efficiency. Anyway, the cost of these latter solutions is still too high for a mass application on cars.…”

“…Reduction of number of solar cells and an increase in the conversion performance can be achieved by the application of concentrating PV. This solution uses reflective mirrors (or refractive optic lenses) to concentrate sunlight onto solar cells [3,4]. As the temperature of PV cell increases, the output voltage and conversion efficiency decrease.…”

Abstract. This article presents selected methods of converting solar energy into electricity: photovoltaic cells (PV), converters which use photon-enhanced thermionic emission (PETE), and near-field enhanced thermionic energy conversion systems (NETEC). PETE and NETEC systems are innovative solutions that use the thermionic emission phenomenon and can replace photovoltaic generation of electricity. We did a comparative analysis of such issues as: structure, principle of operation, working temperature and with particular emphasis -efficiency. A comparison of these parameters is shown in the graphs and summarized in the table. Based on the analysis, we have drawn conclusions about previous achievements and development perspectives in the field of converting methods.
