Photovoltaic (PV) cell technology has made great progress over the past few decades, bringing the PV energy cost down to a point where it is competitive to conventional electricity prices. While monofacial panels have historically dominated the market, recent developments in the manufacturing of bifacial panels (collecting light from both faces) have made them accessible for commercial applications. It is therefore imperative to define the design principles so that the steeply expanding market of bifacial modules and PV farms stays on an efficient path. In this paper, we will discuss physics-based models for these next-generation bifacial PV farms for analyzing yield and costs. Besides the conventional farm configurations, tracking systems are gaining market shares aiming to enhance the yield at a lower cost. Within ± 30 ∘ latitudes, we predict a 20%-30% energy gain for fixed-tilt bifacial over monofacial modules and an additional 20%–40% gain for single-axis bifacial tracking. Compound systems such as agrophotovoltaics and floating PV applications may be the possible future for a sustainable merger of food-water-energy systems. We show a competing relation between active light collection on crops and energy yield in an agrophotovoltaics system vs panel density—the final design will be decided by the crop yield or light usage efficacy constraint. The output reliability in terms of soiling and module degradation is also explained in this paper. Solar farms are expected to see 2%–5% loss in revenue in Asia and the Middle East even after optimal cleaning. Additionally, the bifacial modules degrade ∼0.5%–0.6%/year. While there have been several physics-based degradation analyses, the bifacial technology lacks a large enough data set of long-term degradation studies for accurate predictions. The combined economics of reliability against yield will decide the viability of the next generation bifacial PV industry.

“…This practical value of R rear can be achieved through optimal height, elevation and orientation of solar modules etc. 44,45) For simplicity, we suppose that albedo has same solar spectrum as that of standard AM1.5G throughout the paper. Later in the paper, we also compare the results by using real albedo spectrum for various ground surfaces such as grass, sand, tiles, snow etc.…”

Although perovskite (PVK) and bifacial solar cell technologies have gained a rapid emergence in recent years, integration of PVK with low-cost high-efficiency subcell in a bifacial tandem structure is still an area of huge interest. In this work, the potential of FeSi2 thin film solar cell to be used as bottom subcell in a PVK based bifacial tandem cell structure is explored. We use self-consistent electrical-optical model to investigate various terminal topologies of PVK/FeSi2 bifacial tandem solar cell. In particular, we compare a novel three terminal four junction (3T-4J) tandem configuration termed as twin (or double) tandem cell with conventional monolithic two terminal (2T) and mechanically stacked four terminal (4T) bifacial tandem structures having two junction (2J) configuration. We show that the optimal thickness of PVK in 2T-2J tandem configuration is strongly dependent upon magnitude of albedo due to the current-matching constraint between the subcells, whereas both 4T-2J and 3T-4J tandem cells can perform optimally for a broad range of albedo. At optimal cell design, all tandem structures could exhibit efficiency >27.5% at average Earth albedo of ∼30%. Lastly, the results presented in this work provide a complete design space for optimal cell operations and would be beneficial for the development of low-cost high-efficiency PVK based bifacial tandem solar cell.

“…Apart from these main two parameters, front and back electrical/optical parameters, module orientation, module to module distance, NS/EW facing, will be considered in designing the system. The environmental conditions such as, intensity of sunlight, direct and diffuse sunlight, [17] ambient temperature, wind speed, dust and latitude will be influence on the energy production in the system [18]. When sitting the bifacial solar panels, the most two common configurations will be optimal tilted South/North-facing and vertical East/West-facing, and if there are any obstructions in the field view, the annual energy will be decrease [19].…”

“…In designing a PV power station, the main input data of irradiation in the given location will be taken from data bases which will be, National Solar Radiation Database (NSRDB) [22] and NASA surface meteorological and solar energy data base which has access for 40 years of solar meteorological data worldwide [23]. Also, Purdue University meteorological tool (PUMET) has come up with a new software of generating meteorological data files in any location and these details can be directly import into PV design software tools like PVSyst [17]. These obtained global irradiation at the specific location can be effect on bifacial panels rear side in four different ways, 1.Sky diffuse irradiance, 2.Ground reflected irradiance, 3.Structure reflected irradiance and 4.Direct irradiation on the back surface [24].…”

This paper is based and written on performance analysis of a 10kW Grid-connected solar power system with a comparison in integration of bifacial photovoltaic systems vs mono-facial photovoltaic systems. Thus, all these tastings were carried out on computer simulations using PVSyst6 software & MATLAB/Simulink. These simulations were done considering different albedos and tilt angles in order to identify power variations under different environmental conditions. The selected panels used monocrystalline type-high efficiency cells, both in bifacial and mono-facial and therefore, the technical parameters of both cell types will be the same in operating conditions. With the results obtained, it has shown the power gain in ground mounted-grid connected bifacial solar system is 23% more than the mono-facial solar power system and using these details, the researcher proposed a table that represents, most suitable PV panels for different site conditions.
