Crystalline silicon (c‐Si) solar cells have dominated the photovoltaic market due to their superior mechanical and thermal robustness, nonhazardous nature, optimal energy bandgap, and the availability of established manufacturing techniques. However, conventional c‐Si solar cells fabricated through thermal doping processes present challenges such as high recombination rates and increased production costs. Recently, dopant‐free solar cells have emerged as a promising next‐generation approach; they offer numerous advantages, such as reduced recombination, cost‐effectiveness, environmental friendliness, and applicability to nano‐ and submicrometer structures. This review evaluates the strengths and weaknesses of dopant‐free passivating contact materials for emitters, tracing the development of dopant‐free solar cells from the earliest reports to the current state‐of‐the‐art. A systematic evaluation of these materials based on their electrical and optical properties, coating conformality, stability, and overall photovoltaic performance is presented. Moreover, the limitations of dopant‐free solar cells are identified and strategies to further enhance their efficiency are proposed.

“…Conductive PEDOT:PSS films exhibit lower mechanical stability due to the hydrophilic nature of PSS. Moisture due to PSS also decreases the cohesion among PEDOT grains resulting in lower conductivity. − In order to solve these problems, a lot of research has been carried out by researchers in the last several years by copolymerization, − mixing of suitable polymers, − ,, inorganic silanes, ,− and hydrophobic materials, , and protective overcoating. , Organosilicate derivatives are particularly interesting because they can act as a good bridging and compatible material between the inorganic ITO anode surface and the adjacent organic layer with good adhesion property. Recently, several studies reported organo-silicates with good mechanical hardness and hydrophobicity.…”

We report a simple approach to enhance the mechanical stability and the hydrophobic property of the poly(3,4ethylenedioxythiophene) (PEDOT) transparent conductive films (TCFs) by an in situ sol−gel hybrid approach. Poly-(styrenesulfonate-co-allyl methacrylate) [P(SS-co-AMA)] was used as a template material to synthesize PEDOT:P(SS-co-AMA) aqueous dispersion. PEDOT:P(SS-co-AMA)/silica hybrid films were then prepared by thiol−ene click and sol−gel reactions using silane precursors like 3-mercaptopropyltrimethoxysilane (MPTMS), tetraethyl orthosilicate (TEOS) and perfluorooctyltriethoxysilane (POTES). Pristine PEDOT:P(SS-co-AMA) films on glass showed the electrical conductivity (σ) of 0.07 S/cm, while secondary doping with 5% DMSO increased the conductivity to 77.13 S/cm (transmittance over 92%). As silica is introduced, the electrical conductivity of the PEDOT:P(SS-co-AMA)/silica hybrid films decreased and was in the range of 2.27−76.20 S/cm. Furthermore, the silica hybrid films showed transmittance, >92%; water contact angle, >100°; and pencil hardness, >6H indicating improved hydrophobic property and mechanical stability due to the cross-linked silica network, perfluoro octyl moiety and good compatibility between the organic/inorganic phases. The PEDOT-silica hybrid films with good transparency and electrical conductivity and superior hydrophobic and mechanical properties are suitable candidates for durable optoelectronic device applications.

“…[4] For the PEDOT:PSS/Si HHSCs with the structure of "front PEDOT:PSS" in which the PEDOT:PSS layer acts as the optical window and hole transport layer, efficiencies of 16-18% were achieved. [5][6][7] On the other hand, devices with the "back PEDOT:PSS" structure, where PEDOT: PSS hole transport layer was spin coated at backside of the Si substrates to prevent the parasitic absorption of PEDOT:PSS, have achieved the highest efficiencies of 18.8% on n-Si substrates and 20.6% on p-Si substrates. [8,9] However, research on p-Si-based low-temperature solutionprocessed high-efficiency solar cells has not been achieved yet.…”

With the introduction of the concept of dopant‐free carrier‐selective contact for c‐Si photovoltaics, Si‐based heterojunction solar cells can greatly reduce production costs by optimizing the manufacturing process while maintaining high power conversion efficiency. Compared with processes that rely on complex vacuum equipment, low‐temperature solution processing has many advantages over conventional silicon solar cells. However, research on low‐cost and high‐efficiency solar cells based on p‐type crystalline silicon is relatively rare. From the point of view regards energy band matching, the inorganic metal oxide semiconductor material ZnO is well suited for low‐cost solution method studies due to its easy preparation, very high transmittance in the visible spectrum, low cost, and suitable energy levels matching p‐Si. Herein, ZnO is spin coated on the back of p‐Si to form a heterojunction, together with spin coating of PEDOT:PSS on the front side as the hole transport layer and passivation layer, a PEDOT:PSS/p‐Si/ZnO‐structured p‐Si‐based backcontact hybrid solar cell is successfully fabricated at low temperature (≤135 °C) via solution process with a PCE of 9.77% (Voc = 0.56 V, Jsc = 25.99 mA cm−2, fill factor = 67.10%). This work provides a promising approach for fabricating high‐performance and low‐cost silicon‐based heterojunction solar cells.
