“…The most remarkable achievements in this category have obtained an efficiency of 24.91% by utilizing a SnO x transparent electrode as a substitute for the conventional indium‐based layer; [ 146 ] 2) Using a bilayer TCO structure consisting of both In‐rich and In‐free TCO. For example, an ITO capping layer can be applied on top of a thick AZO layer, which maintains conductivity while significantly minimizing the reliance on indium; [ 147 ] 3). Reducing TCO thickness and incorporating additional optical capping layers, such as MgF x , SiO x , and TiO x , to compensate for the poor antireflection.…”

Solar photovoltaics (PV) are poised to be crucial in limiting global warming by replacing traditional fossil fuel generation. Within the PV community, crystalline silicon (c‐Si) solar cells currently dominate, having made significant efficiency breakthroughs in recent years. These advancements are primarily due to innovations in solar cell technology, particularly in developing passivating contact schemes. As such, this review article comprehensively examines the evolution of high‐efficiency c‐Si solar cells, adopting a historical perspective to investigate the advancements in passivation contact techniques and materials to state‐of‐the‐art cell designs. Additionally, this work deeply studies the recent advances and critical design principles underlying each developed passivation scheme. Eventually, this work identifies existing challenges and proposes insights into future directions for c‐Si solar cells through diverse passivating contact strategies.

“…Low-cost transparent conducting electrodes (TCEs) have received increasing attention recently, which are essential building blocks for diverse optoelectronic devices such as light-emitting diodes, liquid crystal displays, touch screens, and other photonic devices including photovoltaic cells. − In the TCE industry, indium tin oxide (ITO) films are prevalent in commercial devices because ITO has very good electrical conductivity, reliability, and stability. , However, the production cost of the finished products that use ITO films is high because of the requirement of expensive ultrahigh vacuum techniques during the electrode deposition process. − In addition, the major constituent of ITO films is indium, and its demand has increased enormously while natural resources are decreasing over the years. ITO films are also brittle, which makes them unsuitable in flexible optoelectronic devices.…”

We report the significant improvement of the stability of a copper nanowire (Cu NW)-based transparent conducting electrode (TCE). Our study confirms that in contrast to the common use of poly(vinyl pyrrolidone) (PVP) as a surface passivation agent, PVP facilitates the surface oxidation of CuNWs, which, in turn, severely affects the stability and performance of TCEs. To mitigate this issue, polyimide (CPI) is used as a protective layer for the fabrication of the Cu NW TCEs in the absence of PVP, which shows exceptional stability. The conductivity (resistivity) measurement confirms the stability of TCEs over a period of 90 days without any major degradation, while the conductivity of the reference TCE degrades completely after ∼15 days. In addition, we also demonstrate the device application of our Cu NW TCEs by fabricating a thin-film transistor (TFT) and an organic solar cell showing good operational stability. This study provides an insight into the role of PVP in the poor stability of Cu NWs and offers an alternative for the fabrication of Cu NW-based TCEs with improved stability.

Silicon nanowires can improve broadband optical absorption and reduce the radial carrier collection distance in solar cell devices. The disordered nanowire arrays grown by the Plasma-Enhanced Chemical Vapor Deposition method are attractive because they can be embedded on low-cost substrates such as glass, and are compatible with large areas. Here, we experimentally demonstrate that reactive Hydrogen ions with increasing concentrations are doped to construct nanowire architectures in amorphous silicon solar cells. Similar to our investigated planar a-Si: H layers, the amorphous silicon nanowires exhibit a loss function coefficient of about 105/cm. From the reflectivity function, it can be shown that the nanostructures can offer a reliable carrier pool. Our results show that the addition of nanowires can increase the efficiency of a-Si solar cells from 1.11% to 1.57%. The input-photon-to-current conversion efficiency spectrum shows effective carrier collection from 1.2 to 2.2 eV of incident light and the nanowire devices show an increase in short-circuit current of 15% with amorphous Si and 26% with nanocrystalline Si compared to planar devices appropriate.
