They interpreted the obtained results by an existence of a strong built-in field at the interface between Pt QDs with MWNTs and P3OT polymer leading to efficient exciton dissociation and charge separation between P3OT and MWNT in the vicinity of Pt QDs. In addition, owing to the increase in optical electrical field inside the photoactive layer, the inclusion of Pt nanoparticles should enhance an optical absorption and consequently increase photoconversion efficiency. Overall, insufficient light absorption of QDs, charge recombination and trapping at interface with CNTs and polymer as a rule results in poor photovoltaic performance.

17 Left a UV–Vis–NIR spectrum of sediment and supernatant fraction from centrifugation process of SWNT films on glass. M11, S22, and S11 represents the band-gap transitions in metallic and semiconducting SWNTs; b normalized photocurrent spectra of the SWNT/n-Si solar cell devices (supernatant and sediment) showing a current band matching the S11 absorbance band. Right a schematic energy band diagram of SWNT/n-Si heterojunction based on the Anderson model. Electron affinity, χ, and conduction band offset, ΔEc, for SWNT and n-Si are shown in the energy band diagram; b SEM images of cross-sectional view of SWNT/n-Si interface [33].

Nevertheless, today a-Si solars attract growing interest as a light weigh, thin film, flexible and cost effective alternative to crystalline silicon photovoltaics. The research of CNT/a-Si hybrids is now in the beginning stage; however, recent studies already indicated a potential for future PV applications. Schriver et al. [250] examined the photoactive properties of MWNT networks in junction with a-Si undoped thin film. 25 mA/cm2) that can be associated with the use of MWNTs (instead of s-SWNTs) and undoped a-Si (instead of n-doped Si).
