Abstract
AbstractThe 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 calculated to be around $0.36/W(DC) at a long‐term potential efficiency of 24%. The manufacturing cost for the TF‐VLS growth portion is estimated to be ~$23/m2, a significant reduction compared with traditional metalorganic chemical vapor deposition. The analysis here suggests the TF‐VLS growth mode could enable lower‐cost, high‐efficiency III‐V photovoltaics compared with manufacturing methods used today and open up possibilities for other optoelectronic applications as well.
