Study on Diamond Like Carbon-Based Photovoltaic Devices

The objective of this proposed research is to develop carbon-based photovoltaic cells. Because of the diamond like carbon films used as the antireflective layer of solar cells, as well as nano carbon tube the applied on the field of solar photovoltaic were developed rapidly. In recent years, the carbon related materials used for solar applications becomes a promising research to dominate the new trend of photovoltaic area, and the future is full of potential. This aims of project is to study and develop the carbon-based photovoltaic cells. Approach focus on (1) doped and undoped carbon-based films prepared by electrodeposition (wet) and vacuum coating (dry) methods, . (2) Silicon, ITO and metal used as substrates for carbon-based films growth. The relationship between Growth parameters of DLC films and film properties are also studied(3) preparation of a variety of PV cells and analysis of optoelectronic characteristics, (4) investigating the effect of film thickness, heat stability and surface roughness on the PV properties. Research areas include: First year: (1) Study the nature of the DLC film grown on n-Si, p-Si, ITO and metallic substrates. (2)Build up the relevant relations among growth parameters and film’s properties. (3) Prepare photovoltaic cells with structures, such as: MIM/Sckottky types. (4) Explore the relationship among the growth parameters, film’s properties and characteristics of PV cells. Second year (1) Prepare photovoltaic cells with structures, such as: MIS & p-i-n type structure. (2) Build up the relevant relations among growth parameters and characteristics of PV cells, such as open circuit voltage and short circuit current. (3) Investigate of the characteristics of PV cells, such as: carrier transport phenomena, optical response and quantum efficiency. Third year (1) Preparation hetero-junction photovoltaic cells, Such as: Full Spectrum structure & Superlattice structure type. (2) Build up the relevant relations among growth parameters and characteristics of PV cells, such as open circuit voltage and short circuit current.. (3) Investigate of the characteristics of PV cells, such as: carrier transport phenomena, optical response and quantum efficiency.
