We developed and designed a bifacial four-terminal perovskite (PVK)/crystalline silicon (c-Si) heterojunction (HJ) tandem solar cell configuration albedo reflection in which the c-Si HJ bottom sub-cell absorbs the solar spectrum from both the front and rear sides (reflected light from the background such as green grass, white sand, red brick, roofing shingle, snow, etc.). Using the albedo reflection and the subsequent short-circuit current density, the conversion efficiency of the PVK-filtered c-Si HJ bottom sub-cell was improved regardless of the PVK top sub-cell properties. This approach achieved a conversion efficiency exceeding 30%, which is higher than those of both the top and bottom sub-cells. Notably, this efficiency is also greater than the Schockley–Quiesser limit of the c-Si solar cell (approximately 29.43%). The proposed approach has the potential to lower industrial solar cell production costs in the near future.

“…[122] Bifacial perovskite/Si tandem solar cells allow the use of the perovskite top cell with a lower bandgap than that used in a monofacial tandem, enabling enhanced PCE and elongating stability due to reduced halide phase segregation. [122] Because of the higher power generation enabled by the bifacial feature, the cost benefits of bifacial perovskite/c-Si tandem cells are expected to be larger than their monofacial equivalent, [107,115] or the real-world application of bifacial perovskite/Si modules, the installation type, and geological conditions of the installation site need to be taken into consideration to maximize the solar power generation gains (Figure 11g).

PV technologies need to advance further in terms of a substantial increase in PV module power generation, reduction in module prices, and improvement in long-term reliability, eventually realizing low levelized costs of electricity (LCOE) that are compatible with standard electricity prices in the energy market. The PV industry's future development necessitates increased attention to emerging techniques with the potential to achieve high power generation at low costs.Increasing the power output per unit area of solar panels at low additional manufacturing costs is crucial for further lowering the PV-generated electricity price. One of the simplest and inexpensive strategies for increasing the power output density of a solar panel is to harvest reflected and diffuse sunlight from the ground by employing bifacial designs. The concept of bifacial solar cells can date back to the 1960s, but the momentum to bring bifacial solar panels to the market has been gradually realized in the last decade as one of the latest technological advances in PV manufacturing. [4] The mainstream crystalline silicon (c-Si) PV module manufacturers are now producing bifacial silicon solar modules based on different cell technologies. The trend shows that bifacial solar cells and modules are increasingly important in today's PV market and may soon become the cost-effective PV standard. [5] Unlike c-Si solar cells, efficient bifacial designs have not been demonstrated in commercial inorganic thin-film PV technologies because the polycrystalline inorganic thin films suffer from short carrier lifetimes and high rear surface recombination, limiting their bifacial PV performance. Metal halide perovskite solar cells (PSCs) have generated great interest in the PV research and industry, owing to their fast-growing power conversion efficiencies (PCEs), [6] outstanding optoelectronic properties, [7] ease of production, [8] low estimated manufacturing costs, [9] and readiness to take steps toward commercialization. [10] Within a decade, PSCs have rapidly evolved from a newcomer to a leading competitor to rival other established PV technologies.The development of PSCs opens up a golden opportunity to realize efficient bifacial thin-film solar cells. Figure 1 depicts the bifacial architecture for PSCs, summarizes the unique optoelectronic properties of perovskites that enable high bifacial performance, and highlights the advantages of bifacial Bifacial solar cells hold the potential to achieve a higher power output per unit area than conventional monofacial devices without significantly increasing manufacturing costs. However, efficient bifacial designs are challenging to implement in inorganic thin-film solar cells because of their short carrier lifetimes and high rear surface recombination. The emergence of perovskite photovoltaic (PV) technology creates a golden opportunity to realize efficient bifacial thin-film solar cells, owing to their outstanding optoelectronic properties and unique features of device physics. More importantly, transparent cond...

“…The former has recently been achieved by perovskite/silicon tandem cells. [ 119 ] The later will require the development of low temperature processes and inexpensive novel materials for passivation and carrier‐selective contacts. To this end research must be directed toward the replacement of the doped silicon layer with dopant free heterocontacts which can be evaporated, spin, and spray coated.…”

All other nanotube conformations (0° < θ < 30°) are referred to as being chiral. In this 1D system, circumferential electron confinement results in SWCNTs that are either metallic (m) or semiconducting (s) and the innate ability of small changes in diameter to impart large changes in the spectral position (size) of absorption maxima (bandgap) of the SWCNTs. [1a,2] For each chiral species these maxima appear as sets of discrete excitonic transitions (S 11 , S 22 , S 33 …etc.) in the infrared, visible, and ultraviolet and the ability to tune them with structure has made SWCNTs one of the most intensively studied nanomaterials of the past two decades. [3] SWCNTs meet all of the requirements for next generation technology to become flexible and potentially made entirely from carbon to aid disposal at the end of the product life-cycle. Applications for SWCNTs can be found across all fields of science including photonics, [4] telecommunications, [5] batteries, [6] fuel cells, [7] high frequency transistors, [8] biosensors, [9] novel memory devices, [10] molecular contacts, [11] and cancer research. [12] In particular, their chirality dependent bandgap, chemical stability, conductivity, and hole selectivity have made them attractive for new generation solar cells and light sensitive elements. [13] For example, there are 200 species in the dia meter range of 0.6-2 nm, which have first (S 11) and second (S 22) optical transitions ranging from 2.57 eV (visible) to 0.5 eV (near-infrared) and these already cover a majority of the solar spectrum (400-2000 nm), Figure 1d. [14] Being solutionprocessable and fiber-shaped, CNTs can easily be integrated into different types of solar cells with distinct functions. For example, as a photoactive layer in organic solar cell, a transparent electrode in silicon and perovskite solar cells or as counter electrode in dye-sensitized solar cells. [15] However, despite their promise, the number of real-world applications for SWCNTs in the photovoltaics (PV) industry continue to remain limited. The reasons for this are manifold and include the comparatively lower power conversion efficiency (PCE) and device area of SWCNT-based technologies, which drive simple cost-benefit arguments to retool existing production lines, ongoing challenges to orientate and control the structure of CNT films in a scalable manner, spurious health concerns associated with the use of CNTs [16] and importantly, the fact that it is still not possible to selectively synthesize SWCNTs of arbitrarily defined chirality. Most synthesis methods produce a 2:1 mixture of many semiconducting and metallic chiral types and even the CoMoCAT synthesis process, [17] which is well known to be highly enriched in small diameter (6,5), still contains at least 15 other chiral species in low concentration. Research efforts to achieve chiral specific growth are ongoing The use of carbon nanotubes (CNTs) in photovoltaics could have significant ramifications on the commercial solar cell market. Three interrelated research directions within t...
