“…5. This result is consistent with a previous report on Si/PEDOT:PSS hybrid cell 21 It is further noted that when the SiOx layer is fully removed by extended HF etching time of 150s, the V oc obtained is only about 0.54 V (support information, Fig. Consequently, the SiNWs without the ozone treatment have only a very thin SiOx layer on the SiNWs, as seen in Fig.…”

This may be due to the ozone treatment that has resulted in a more hydrophilic surface, which facilitates the better coverage of the PEDOT:PSS layer on the surface of the SiNWs 21. The PEDOT:PSS layer deposited on SiNWs subjected to surface treatment displays a smoother surface, as shown in theFig.…”

A simple two-step surface treatment process is proposed to boost the efficiency of silicon nanowire/PEDOT:PSS hybrid solar cells. The Si nanowires (SiNWs) are first subjected to a low temperature ozone treatment to form a surface sacrificial oxide, followed by a HF etching process to partially remove the oxide. TEM investigation demonstrates that a clean SiNW surface is achieved after the treatment, in contrast to untreated SiNWs that have Ag nanoparticles left on the surface from the metal-catalyzed etching process that is used to form the SiNWs. The cleaner SiNW surface achieved and the thin layer of residual SiO2 on the SiNWs have been found to improve the performance of the hybrid solar cells. Overall, the surface recombination of the hybrid SiNW solar cells is greatly suppressed, resulting in a remarkably improved open circuit voltage of 0.58 V. The power conversion efficiency has also increased from about 10% to 12.4%. The two-step surface treatment method is promising in enhancing the photovoltaic performance of the hybrid silicon solar cells, and can also be applied to other silicon nanostructure based solar cells.

This article focuses on the work which deals with the effect of introducing macroporous silicon as the cathode of hybrid solar cell. This work shows that the photocurrent of bulkheterojunction hybrid solar cell can be enhanced by using macroporous silicon (macroPSi) as the cathode that provided increased effective contact surface area at the interface of organic-inorganic material. The organic compound (3-hexylthiophene) (P3HT) and phenyl-C61-butyric acid methyl ester (PCBM) polymer blend at 1:1 ratio was used to fabricate the solar cell. It was found that the pore-diameter of the porous silicon plays an important role on short-circuit current of the fabricated hybrid solar cell. Huge enhancement of short-circuit current density (~ 73 times) was obtained when the average pore diameter of macro-PSi was comparable to the photogenerated carrier transport length of the photoactive polymer. The annealing of the whole structure further enhanced the overall performance of the fabricated hybrid solar cell.
