“…The formation of voids in the hybrid solar cell led to a high R s of 6.03 × 10 −1 Ω·cm 2 and a low R sh of 1.58 × 10 Ω·cm 2 as compared to the values at higher spin speeds, resulting in lower V oc and FF. Yang, et al reported that voids are likely to form local shunts, which cause the deterioration of V oc and FF [22]. This trend is in accord with our results.…”

Silicon (Si)/organic polymer hybrid solar cells have great potential for becoming cost-effective and efficient energy-harvesting devices. We report herein on the effects of polymer coverage and the rear electrode on the device performance of Si/poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate) (PEDOT:PSS) hybrid solar cells with micro-pyramidal structures. These hybrid solar cells provided adequate generation of charge carriers owing to the suppression of reflectance to below 13%. Additionally, the separation of the photogenerated charge carriers at the micro-pyramidal-structured Si/PEDOT:PSS interface regions and their collection at the electrodes were dramatically improved by tuning the adhesion areas of the PEDOT:PSS layer and the rear electrode materials, thereby attaining a power conversion efficiency of 8.25%. These findings suggest that it is important to control the PEDOT:PSS coverage and to optimize the rear electrode materials in order to achieve highly efficient separation of the charge carriers and their effective collection in micro-textured hybrid solar cells.

“…[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.

“…Yang, Liu, and Du et al, have reported on the influence of voids on the photovoltaic performance of micro-pyramidal-structured Si/PEDOT:PSS hybrid solar cells. They have also suggested that the occurrence of the voids at the Si/PEDOT:PSS interface is likely to form local shunts, which cause the deterioration of the V oc and FF values [24] . From these factors, the honeycomb structured hybrid solar cell resulted in low V oc and FF values, thereby leading to the degradation of the PCE.…”
