Efficient Inverted Perovskite Solar Cell with Indium-Doped NiOx

• Colombian researchers achieve 20.06% efficiency with innovative NiOxIn solar cell, offering stability and cost-effectiveness in renewable energy technology.

Researchers from Universidad de los Andes in Colombia have developed an efficient inverted perovskite solar cell using indium-doped nickel oxide as the hole transport layer (HTL). The champion device achieved an impressive efficiency of 20.06% with excellent stability. The NiOx material used in the cell offers high energy gap, chemical stability, low toxicity, and cost-effective processing.

The team utilized a one-step electrochemical deposition process to build the NiOxIn HTL, which allowed for precise control of thickness and structure. The cell consisted of layers including indium tin oxide substrate, NiOxIn HTL, perovskite absorber, PCBM electron transport layer, BCP buffer layer, and silver metal contact. The champion cell demonstrated a power conversion efficiency of 20.06% and maintained performance under real operating conditions for over 3,000 seconds. The researchers concluded that indium doping of NiOx is a novel and efficient method to enhance the photovoltaic performance of inverted perovskite solar cells.
