“…1,2) Research on how to texture the surface effectively has been conducted for a long time. [3][4][5][6][7][8][9][10][11] In large-scale production, because of its lowest cost and highest yield, alkaline etching has been the most popular method. Owing to the relatively low boiling point of isopropanol (IPA), the instability of NaOH and IPA solutions often results in poor reproducibility of surface morphology.…”

Owing to the volatilization of isopropanol (IPA), instability in the alkaline texturization of monocrystalline silicon has been a big problem for a long time. Many additives were adapted to replace IPA, such as high boiling point alcohols. In this experiment, as a new attempt, sodium lauryl sulfate (SDS), a type of anionic surfactant, was used as the additive in NaOH solution. The etching properties of silicon in 2 wt % NaOH/15-30 mg/L SDS solution were analyzed. To improve the wettability of silicon, two types of metal salt, NaCl and Na 2 CO 3 with concentration from 2 to 15 wt %, were applied to the 2 wt % NaOH/15 mg/L SDS solution. The results showed that the effect of NaCl was better than that of Na 2 CO 3 . Finally, the role of the additive was discussed. #

“…For an external electrical contact, the backsided aluminum electrode was deposited (before growing SiNWs) by using the thermal deposition method onto the highly doped very thin layer inside the back of a silicon wafer. The detailed information about the fabrication of backsided electrode and SiNWs can be found in our already reported results [15,16]. For the fabrication of a stamped hybrid cell, a glass substrate was cleaned with detergent, distilled water, acetone and isopropyl alcohol.…”

A novel stamped hybrid solar cell was proposed using the stamping transfer technique by stamping an active PEDOT:PSS thin layer onto the top of silicon nanowires (SiNWs). Compared to a bulk-type counterpart that fully embeds SiNWs inside PEDOT:PSS, an increase in the photovoltaic efficiency was observed by a factor of ∼4.6, along with improvements in both electrical and optical responses for the stamped hybrid cell. Such improvements for hybrid cells was due to the formation of well-connected and linearly aligned active PEDOT:PSS channels at the top ends of the nanowires after the stamping process. These stamped channels facilitated not only to improve the charge transport, light absorption, but also to decrease the free carriers as well as exciton recombination losses for stamped hybrid solar cells.

“…For the top-down approach, SiNWs are carved (etched) from their substrate as shown in Figure 3. While lithography [64], direct reactive ion etching (DRIE) [65] and electroless etching (EE) [66][67][68][69] are the most frequently reported techniques for the top-bottom SiNW fabrication approach. Metal assisted chemical etching (MACE) method is comprehensively reported for the development of the SiNW array especially for PEDOT:PSS-SiNW solar cell application.…”

Among various photovoltaic devices, the poly 3, 4-ethylenedioxythiophene:poly styrenesulfonate (PEDOT:PSS) and silicon nanowire (SiNW)-based hybrid solar cell is getting momentum for the next generation solar cell. Although, the power-conversion efficiency of the PEDOT:PSS–SiNW hybrid solar cell has already been reported above 13% by many researchers, it is still at a primitive stage and requires comprehensive research and developments. When SiNWs interact with conjugate polymer PEDOT:PSS, the various aspects of SiNW array are required to optimize for high efficiency hybrid solar cell. Therefore, the designing of silicon nanowire (SiNW) array is a crucial aspect for an efficient PEDOT:PSS–SiNW hybrid solar cell, where PEDOT:PSS plays a role as a conductor with an transparent optical window just-like as metal-semiconductor Schottky solar cell. This short review mainly focuses on the current research trends for the general, electrical, optical and photovoltaic design issues associated with SiNW array for PEDOT:PSS–SiNW hybrid solar cells. The foremost features including the morphology, surface traps, doping of SiNW, which limit the efficiency of the PEDOT:PSS–SiNW hybrid solar cell, will be addressed and reviewed. Finally, the SiNW design issues for boosting up the fill-factor, short-circuit current and open-circuit voltage will be highlighted and discussed.
