“…[259][260][261][262][263][264][265][266][267][268][269] Compared with the conventional fabrication process of crystalline Si solar cells these hybrid solar cells could be fabricated at significantly lower costs. Instead of the high-temperature diffusion or expensive implantation process to form a p-n junction, simply a polymer layer was added on top of a n-type Si wafer.…”

In hybrid photovoltaics, an organic and an inorganic semiconductor are combined in the active layer, with the advantages of both material classes in a single device. The organic component contributes towards the possibility for wet chemical device preparation with potentially low costs in combination with achieving flexible devices. From the inorganic component an increase in stability, as well as superior opto‐electronic properties, is added. Given the large diversity of organic and inorganic semiconductors, a large number of possible realizations of hybrid solar cells emerge. In the present review, we limit to hybrid solar cells which combine conjugated polymers with inorganic materials such as titanium dioxide, zinc oxide, silicon, germanium and quantum dots to keep focused. Particular emphasis is put on different routes to tailor nanostructures, such as the use of semiconductor block copolymers. The inorganic component is either synthesized directly in one of the blocks or added as a pre‐synthesized nanomaterial to form the hybrid material. Alternatively, the block copolymer is used as a structure‐directing template in a sol–gel synthesis approach to have tailored inorganic nanostructures, which are back‐filled with the organic component to fabricate the hybrid material. Hybrid solar cells based on crystalline Si are discussed for comparison.

“…[ 4,5 ] Besides, a thin active layer has the inherent advantages for enhanced charge carrier diffusion and collection, which can properly relax the requirement of the material quality for the equivalent device performance. [ 6 ] The c-Si thin fi lm solar cells are also attractive due to the potential for the lower Auger recombination and the improved open circuit voltage ( V oc ). [ 7 ] In consideration of simplifying procedures, recently developed organic/silicon hybrid solar cells, especially for the heterojunctions composed of the organic hole-transporting poly(3,4-ethylene dioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) on n-type c-Si provide a promising new concept with easy fabrication process and low energy cost.…”

Periodic nanocone–nanopillar dual‐structured arrays are wet chemical etched on 20 μm‐thick crystalline silicon substrates, enabling the realization of excellent light absorption properties and enhanced electrical contact with PEDOT:PSS. The finally textured silicon/PEDOT:PSS thin film hybrid solar cell shows a power conversion efficiency of 12.2%. These results provide a viable route toward high‐performance thin film silicon/polymer hybrid cells by shape‐controlled nanotexturing.

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.
