p‐Toluenesulfonic acid/dimethyl sulfoxide (PTSA/DMSO)‐treated poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS)/crystalline‐silicon (c‐Si) hybrid solar cells with a solution‐processed anti‐reflection coating of TiO2 exhibit a record power conversion efficiency of 15.5%. Additionally, the performance stability of the hybrid device for both air storage and light exposure is improved due to removal of the PSS matrix from the PTSA/DMSO‐treated PEDOT:PSS thin film.

“…Applications to the front textured surface of silicon solar cells have recently led to Yang et al demonstrating open-circuit voltages (V oc ) of 634 mV and S of 100 cm/s [11] while Zhang et al have reported the same V oc of 634 mV applying the PEDOT:PSS passivating hole contact layer to the rear side of silicon-based solar cells [12]. In contrast, Schmidt et al have demonstrated better electronic properties for rear-passivated PEDOT:PSS solar cells, where an emitter saturation current density (J oe ) of 80 fA/cm 2 and an implied open-circuit voltage (iV oc ) of 690 mV have been reported [13], [14]. This was further improved by Zielke et al, who achieved J oe of 46 fA/cm 2 by optimizing the silicon surface treatment prior to the deposition of PEDOT:PSS [15].…”

While PEDOT: PSS and PSS films are promising approaches to contacting or passivating silicon, they do exhibit severe degradation under ambient conditions, and thus require capping films in order to inhibit degradation [13].…”

Organic-inorganic hybrid solar cells display potential to be high efficiency and low cost photovoltaics due to combined advantages of high stability, high mobility and well developed fabrication process from inorganic materials and the properties to adjust organic molecule structure, absorption spectrum and bandgap from solution processable organics. Heterojunction photovoltaics formed by silicon and organics at low temperature has drawn great interests over past five years and the reported highest power conversion efficiency (PCE) has achieved up to 13.8%. The emerging of nanotechnology allows for silicon micro/nano structures including silicon nanowires, pyramids and nanocones with excellent light absorption properties which can greatly reduce the consumption of silicon materials as well as the purity dependence. The micro/nano structures also exhibit the advantages to offer larger junction area and more effective separation pathways for charge carriers. It is noticeable that silicon nanowire-based flexible hybrid solar cells with tens of micrometers silicon substrate thickness have achieved the PCE of above 12% adopting the most popular commercialized conjugated polymer poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate) (PEDOT:PSS). With the rapid developments of new organic materials and interface engineering methods, different kinds of organic-silicon hybrid solar cells has been reported and shown superior photovoltaic characteristics. The adopted organics include PEDOT:PSS, poly(3-hexylthiophene) (P3HT), 2,2',7,7'-Tetrakis-(N,N-di-4-methoxyphenylamino)-9,9'-spirobifluorene (Spiro-OMeTAD), poly(3-octylthiophene) (P3OT), fullerene derivative and so on. This paper reviews the device structures of silicon-based hybrid solar cells, working mechanism and related organic molecular. The hybrid heterojunction with different materials and fabrication processes has been discussed. The last section summarizes the method used to improve the performance of the hybrid solar cells and depicts the challenges and prospects of the silicon-based hybrid solar cells in the near future.
