“…Although much effort has devoted to improving the fabrication techniques of C/Si heterojunction PV cells ( Table 1 ) and adjusting the bandgap of a‐C, the application of a‐C/Si heterojunction PV cells have developed slowly due to the high density of defects, the difficulty of controlling the sp 2 /sp 3 ratio of the a‐C, the inhomogeneity of dopants, and the extreme growth process of a‐C …”

In the last few decades, advances and breakthroughs of carbon materials have been witnessed in both scientific fundamentals and potential applications. The combination of carbon materials with traditional silicon semiconductors to fabricate solar cells has been a promising field of carbon science. The power conversion efficiency has reached 15-17% with an astonishing speed, and the diversity of systems stimulates interest in further research. Here, the historical development and state-of-the-art carbon/silicon heterojunction solar cells are covered. Firstly, the basic concept and mechanism of carbon/silicon solar cells are introduced with a specific focus on solar cells assembled with carbon nanotubes and graphene due to their unique structures and properties. Then, several key technologies with special electrical and optical designs are introduced to improve the cell performance, such as chemical doping, interface passivation, anti-reflection coatings, and textured surfaces. Finally, potential pathways and opportunities based on the carbon/silicon heterojunction are envisaged. The aspects discussed here may enable researchers to better understand the photovoltaic effect of carbon/silicon heterojunctions and to optimize the design of graphene-based photodevices for a wide range of applications.

“…5. The result shows the optical band gap of a-C:I thin film at 1.0 g is lowest compared to that of other samples which regarding the sample becomes more graphitic [11]. The increased in optical band gap with the iodine incorporation can be explained due to the formation of C-I network in the thin films which lead to increase the sp 2 bonded.…”

odine incorporation to amorphous carbon (a-C) thin films offers many advantages and a full understanding of the properties of iodine doped amorphous carbon (a-C:I) thin films which is necessary for applications like optoelectronics devices and photovoltaic solar cells. Iodine doped amorphous carbon thin films have been doped by thermal chemical vapour deposition (CVD) technique at different amount of iodine. The effects of iodine amount on the properties of a-C:I thin films have been investigated using standard measurement techniques and discussed. FESEM studies have been performed on the doped films for the surface morphology studies. Raman studies have been carried out on the doped samples for the chemical bonding of carbon atoms. The sp2 and sp3 contents have found to be dependent on the amount of iodine. For evaluation of the electrical and optical properties of the doped films, the current-voltage (I-V) measurement and UV-Vis-NIR spectroscopy have been performed on the a-C:I thin films. It has been observed that the a-C:I thin films doped with 1g has higher electrical conductivity and lowest optical band gap.

“…The as-deposited (undoped) a-C has low photoconductivity and shows weakly p-type semiconducting nature [5,6], but to realize the utilization of carbon material as alternative material in optoelectronic devices, controlling the conduction type of the thin film is necessary. Taken into account is the n-C/p-Si hetero-junctions which have been recognize through n-type doping using phosphorus and nitrogen [7] and p-C/n-Si hetero-junctions from the p-type doping of using boron and iodine [8,9].Other than that, in order to increase the efficiency of the cell, a-C films can also be used as a protective anti-reflecting coating for regular silicon solar cells [10].…”

Pure amorphous Carbon (a-C) thin films had been deposited by Aerosol-Assisted CVD (AACVD) onto glass substrate in Argon atmosphere. The camphor oil was chosen as the carbon precursor to prepare the a-C thin films with the deposition time of 15 minutes, 30 minutes, 45 minutes, 60 minutes and 75 minutes. The electrical, optical and structural properties of the deposited a-C were discussed by using the current-voltage solar simulator system, UV-Vis-Nir spectrophotometer and Raman spectroscope respectively. For the electrical characterization, the samples showed the photoresponse performance when being illuminated under AM 1.5 illuminations: 100 mW/cm2, 25°C. Transmittance value for the a-C thin films was also considered high ~80% and the structural analysis by using Raman spectroscope exhibit two main peaks known as the D-peak and G-peak which is typical for the a-C.
