К 125-летию со дня рождения лауреата Нобелевской премии академика Николая Николаевича Семенова Высокоэффективные фотоэлектрические модули с концентраторами солнечного излучения

The paper outlines the results of research and development of solar concentrated photovoltaic modules with an aperture area of 0.5 m^2. Module design was based on Fresnel lenses with inverted pyramids as secondary concentrators of solar irradiance, and multijunction solar cells located in the focus of Fresnel lens. The developed modules are characterized with up to 700X solar concentration ratio and optimal operational thermal regime for solar cells. The efficiency of developed photovoltaic modules exceeds 32% which makes them on par with modules of the similar design developed and manufactured globally.

Solar Cell Performance

The present work aims at decrease the cost of the photovoltaic (PV) solar system by decreasing the area of expensive solar cells by low cost optical concentrators that give the same output power. Output power of two types’ monocrystalline and polycrystalline silicon solar cells has been measured with and without presence of linear focus Fresnel lenses (FL) with different concentration ratios. Cooling system has been used to decrease the effect of temperature on solar cell performance. The results indicated that the increase in the output power is about 5.3 times by using Fresnel lens concentrator without using cooling system in comparison with solar cell without concentrator, while it is about 14.6 times by using cooling system. The efficiency of monocrystalline solar cell without cooling system is about 11.2% for solar irradiance 0.698 kW/m2, this value decrease to 3.3% for solar irradiance 12.4 kW/m2 and concentration ratio 17.7 by using Fresnel lens concentrator, while when using cooling system the efficiency enhance to 12.9% and 8.8% for solar irradiance 0.698 and 12.4, respectively.

Concise Overview

Concentrator Photovoltaic (CPV) technology, by using efficient optical elements, small sizes and high efficiency multi-junction solar cells, can be seen as a bright energy source to produce more cost-effective electricity. The main and basic idea is to replace the use of expensive solar cells with less expensive optical elements made from different materials. This paper aims to give to the readers a rapid and concise overview of CPV and the main characteristics to be considered when designing a CPV system. It reviews the main optical configurations presented in the literature, their advantages and drawbacks, as well as the recent progress in the concentration ratio and the major performances achieved in the field. The paper considers the more recent works, their optical designs, as well as their optical and electrical performances. It also relates the major achievements on the industrial side with the major milestones in CPV developments.

Ray Tracing Model

Abstract In the present work, a ray tracing model based on Snell’s law of refraction is developed using MATLAB for the design of Fresnel lens with spherical facets of equal height. In practice, the facet curvature is approximated by straight line, which causes an increase in spherical aberrations and reduction in concentration ratio. The proposed model takes facet curvature into consideration, which will result in effective utilization of incident solar radiations. Fresnel lenses are available with facets having constant width and facets with constant height. A comparison of spherical aberrations in the two cases has also been presented using different f - numbers (ratio of focal length to aperture diameter). Effect of different parameters like number of facets and refractive index of lens material on concentration ratio is also presented in present study. The proposed ray tracing model is validated with the model developed in SolTrace, an open access software. The predictions from the proposed model are in good agreement with the results of SolTrace model with an average deviations of 6.8% for concentration ratio and 2.2% for focal length.

Fresnel Lenses

A work on development of the high concentration photovoltaic (HCPV) modules with Fresnel lens panels and III-V multijunction cells is presented. A composite structure of the small-aperture area 40x40 (or 60x60) mm2 Fresnel lenses, united in a panel, was realized. A silicate glass sheet (front side of a module) serves as a superstrate for transparent microprisms formed in silicone. Small averaged thickness of the prisms ensures low IR absorption of sunlight in comparison with acrylic Fresnel lenses. Temperature dependences of the optical properties in such a type of the solar concentrators and PV properties of the cells in passive heat dissipation conditions are under consideration. The solar cells are the triple-junction InGaP/(In)GaAs/Ge cells with designated illumination area 1.7-2.3 mm in diameter. A HCPV module consists of the 144 (or 64) sub-modules in 12x12 (or 8x8) configuration. Solar cells are protected from environment in different ways: by side walls of a module body, or by a rear glass sheet at integrated sealing the cells in a back-side module panel. Module design includes refractive smooth-surface secondary lenses. The cell strings are glued to the rear glass surface of the module body using lamination process. Proper quality of the solar cells in a multistage module assembling procedure is ensured owing to specially developed contactless test method, based on analyzing the electroluminescent signals at local photoexitation. For arrangement of the HCPV modules in a solar installation, a number of the solar trackers have been developed and realized for 1-3-5 kWp of the installed power.

Energy Conversion Process

The solar cell photoelectric efficiency is a concept introduced to assess the energy conversion process of photons into electron-hole pairs. A study on the correlation between photoelectric efficiency and semiconductor materials band gap of multijunction solar cells is presented. This is based on an integrated computer model used to perform the simulations over solar standard spectrum AM1.5G as well as a non-standard case, which includes the cells operating in outdoor conditions. We find that over a diffuse solar flux, the solar cell photoelectric efficiency increases whenever the cells are made from a semiconductor material with band gap higher than that optimized over the AM1.5G spectrum. Consequently, this opens a new possibility to increase the photovoltaic modules efficiency.
