Diffusion Based Ex-Situ Group V (P, AS, SB, BI) Doping in Polycrystalline CDTE Thin Film Solar Cells
­ The Problem: Cadmium Telluride (CdTe) solar cells are the second most common photovoltaic (PV) technology in the world, and they can be manufactured quickly and inexpensively, providing a lower‐cost alternative to conventional silicon‐based technologies. However, current commercial CdTe thin film solar cells, which are created using Group I...

Highly Efficient, Cost Effective and Hot-pressed Carbon-based Perovskite Solar Cell
The Problem: Organic-inorganic halide perovskite solar cells (PSCs) have been gaining a lot of attention since it was first fabricated in 2009 owing to their high-power conversion efficiency (PCE) and relatively simple fabrication process. The efficiency of PSCs has crossed 25.5% in just over a decade. A typical PSC has a structure that contains a...
