Thin film solar cells based on the ternary compound Cu2SnS3

Thin-film Silicon Solar Cells

The simplest semiconductor junction that is used in solar cells for separating photogenerated charge carriers is the p-n junction, an interface between the p-type region and ntype region of one semiconductor. Therefore, the basic semiconductor property of a material, the possibility to vary its conductivity by doping, has to be demonstrated first before the material can be considered as a suita...

Electrochemical impedance analysis of SILAR deposited Cu2SnS3 (CTS) thin film

SILAR deposited copper tin sulfide (Cu2SnS3) thin films were used to analyze the study of electrochemical impedance, capacitancevoltage characteristics and currentvoltage characteristics. The photoconversion efficiency of SILAR deposited CTS thin film-based photoelectrochemical cell elucidate with the help of capacitance-Voltage (C-V) Characteristics study by MottSchottky plot and corresponding...

Improving the optical properties of thin film plasmonic solar cells of InP absorber layer using nanowires

In this paper, a thin-film InP-based solar cell designed and simulated. The proposed InP solar cell has a periodic array of plasmonic back-reflector, which consists of a silver layer and two silver nanowires. The indium tin oxide (ITO) layer also utilized as an anti-reflection coating (ARC) layer on top. The design creates a light-trapping structure by using a plasmonic back-reflector and an an...

CZTSSe Thin Film Solar Cells : Surface Treatments

Joglekar, Chinmay S. M.S.Ch.E., Purdue University, May 2014. CZTSSe Thin Film Solar Cells: Surface Treatments. Major Professor: Rakesh Agrawal. Chalcopyrite semiconducting materials, specifically CZTS, are a promising alternative to traditional silicon solar cell technology. Because of the high absorption coefficient; films of the order of 1 μm thickness are sufficient for the fabrication of so...
