“…With a potential application in light emitting diodes [19][20][21], lasers [22][23][24], photodetectors [25][26][27] and other optoelectronic devices, all inorganic lead halide perovskite QDs (IPQDs) could become alternative materials for the down-shifting effect and photovoltaic applications due to their low cost synthesis method, long-time stability, high optical absorption coefficient, as well as controllable and high intensity PL [28][29][30]. Compared with a relatively low PL QY (<50%) in Si QDs [31,32], IPQDs have PL QYs of 80%, 95%, 70%, for red, green, and blue emissions [33].…”

Over the past couple of decades, extensive research has been conducted on silicon (Si) based solar cells, whose power conversion efficiency (PCE) still has limitations because of a mismatched solar spectrum. Recently, a down-shifting effect has provided a new way to improve cell performances by converting ultraviolet (UV) photons to visible light. In this work, caesium lead bromide perovskite quantum dots (CsPbBr3 QDs) are synthesized with a uniform size of 10 nm. Exhibiting strong absorption of near UV light and intense photoluminescence (PL) peak at 515 nm, CsPbBr3 QDs show a potential application of the down-shifting effect. CsPbBr3 QDs/multicrystalline silicon (mc-Si) hybrid structured solar cells are fabricated and systematically studied. Compared with mc-Si solar cells, CsPbBr3 QDs/mc-Si solar cells have obvious improvement in external quantum efficiency (EQE) within the wavelength ranges of both 300 to 500 nm and 700 to 1100 nm, which can be attributed to the down-shifting effect and the anti-reflection property of CsPbBr3 QDs through the formation of CsPbBr3 QDs/mc-Si structures. Furthermore, a detailed discussion of contact resistance and interface defects is provided. As a result, the coated CsPbBr3 QDs are optimized to be two layers and the solar cell exhibits a highest PCE of 14.52%.

“…In this case, PSCs are fabricated on top of a textured silicon solar cell. [8,14,17] A perovskite/silicon TSC is a solar cell in substrate configuration opposite to the superstrate solar cells described in the previous paragraphs of this manuscript. In the remaining section of the manuscript, we focus on solar cells in a substrate configuration.…”

“…(TSCs). [14][15][16][17] The hole transport material (HTM) is an essential element for realizing optimum photovoltaic parameters, particularly, the open-circuit voltage (V OC ) of the PSC. Currently, PSCs with high ECEs are made from organic HTMs (e.g., poly (3,4ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS), 2,2′,7,7′-tetrakis [N,N-di(4-methoxyphenyl) amino]-9,9′spirobifluorene (Spiro-OMeTAD), poly(triaryl amine) (PTAA), and poly(3-hexylthiophene) (P3HT)), which require additional dopant materials and adhesive ingredients (e.g., bathocuproine (BCP)).…”

Efficient hole transport layer (HTL) is crucial for realizing efficient perovskite solar cells (PSCs). In this study, nickel‐oxide (NiOX) thin‐films are investigated as a potential HTL for PSCs. The NiOX films are prepared by electron‐beam physical vapor deposition at low temperatures. The crystalline properties and the work function are determined by X‐ray diffraction and photoelectric yield spectroscopy. The transmission and the complex refractive index of the films are determined by optical spectroscopy and ellipsometry. Furthermore, PSCs are fabricated and characterized. The short‐circuit current density (Jsc) of the PSC is limited by the optical loss due to the NiOx front contact. The optical losses of the front contact are quantified by optical simulations using finite‐difference time‐domain simulations, and a solar cell structure with improved light incoupling is designed. Furthermore, the electrical characteristics of the solar cell are simulated by finite element method simulations. As a result, it is found that the optical losses can be reduced by 70%, and the light incoupling can be improved so that the JSC can be increased by up to 12%, allowing for the realization of PSCs with an energy conversion efficiency of 22%. Findings from the numerical simulations are compared with experimentally realized results.

Perovskite/silicon tandem solar cells (TSCs), especially two-terminal, with a record efficiency of 28% already realized, present great potential as low-cost and efficient substitutes for dominant silicon photovoltaics. Achieving efficiencies exceeding 30% is quite realistic, as indicated by extensive optical simulations. Super light management in monolithic perovskite/silicon TSCs is one of the prerequisites to make this a reality. In this Review, various forms of optical losses, such as reflection loss, parasitic absorption, and current mismatch, are analyzed systematically to provide a better understanding of the performance of perovskite/silicon TSCs. Particularly, a simple refractive index matching rule derived from the Fresnel equation is proposed as a basis for material selection and device design. Meanwhile, an overview of the current strategies and challenges in monolithic perovskite/silicon TSCs is provided, comprising bandgap engineering of perovskites and light trapping methods, aiming to provide guidance for further improvement of tandem devices.
