چکیده
The work focuses on understanding and characterization of the thin-film vapor-liquid-solid (TFVLS) growth technique as a low-cost process technology for III-V thin film solar cells on metal/glass substrates. In the last review period, we have focused on understanding and controlling the nucleation events of TF-VLS InP. Furthermore, optoelectronic characterization of the grown InP has been performed in depth to shed light on the potential PV efficiencies that may be feasible to obtain using this growth technique. Collaboration with Purdue has been initiated to further understand the material performance limits of TF-VLS InP. Finally, in collaboration with NREL, a preliminary cost model is developed.

Deterministic Nucleation of InP on Metal Foils with the Thin-Film Vapor−Liquid−Solid Growth Mode
A method for growth of ultralarge grain (>100 μm) semiconductor thin-films on nonepitaxial substrates was developed via the thin-film vapor−liquid−solid growth mode. The resulting polycrystalline films exhibit similar optoelectronic quality as their single-crystal counterparts. Here, deterministic control of nucleation sites is presented by substrate engineering, enabling user-tuned internuclei...

The authors present a manufacturing cost analysis for producing thin-film indium phosphide modules by combining a novel thin-film vapor–liquid–solid (TF-VLS) growth process with a standard monolithic module platform. The example cell structure is ITO/n-TiO2/p-InP/Mo. For a benchmark scenario of 12% efficient modules, the module cost is estimated to be $0.66/W(DC) and the module cost is calculat...

However, it is often challenging to physically create t...
متن کاملA direct thin-film path towards low-cost large-area III-V photovoltaics
III-V photovoltaics (PVs) have demonstrated the highest power conversion efficiencies for both single- and multi-junction cells. However, expensive epitaxial growth substrates, low precursor utilization rates, long growth times, and large equipment investments restrict applications to concentrated and space photovoltaics (PVs). Here, we demonstrate the first vapor-liquid-solid (VLS) growth of h...
