The hole transport layer (HTL) is a critical component in perovskite solar cells (PSCs), governing charge extraction efficiency and interfacial stability. Molybdenum trioxide (MoO₃), a wide-bandgap transition metal oxide, offers favorable energy alignment and high work function, yet its performance can be further optimized through controlled doping. In this work, lanthanum (La)-doped MoO₃ thin...

The rapid evolution of perovskite photovoltaic technology has positioned cesium lead iodide (CsPbI₃) as a promising candidate for next-generation solar cells due to its exceptional thermal stability, suitable bandgap, and long carrier diffusion length. However, achieving practical device efficiencies remains constrained by suboptimal layer configurations, defect-induced recombination, and...

Copper Iodide (CuI) thin films synthesized using monoethanolamine (MEA) as a green solvent exhibit high optical transparency and uniform planar morphology, supporting their function as efficient hole transport layers (HTLs) in perovskite solar cells. Using this low-temperature, additive-free method, γ-CuI with a zinc-blende structure was successfully obtained. Despite these promising outcomes,...

Perovskite solar cells (PSCs) are a leading candidate for next-generation photovoltaic technology, offering high-power conversion efficiency (PCE) and cost-effective fabrication. While is conventionally used as the electron transport layer (ETL), its required high-temperature crystallization (450) severely limits its integration into flexible devices built on heat-sensitive substrates. The...

Perovskite solar cells (PSCs) have rapidly advanced in recent years, achieving impressive power conversion efficiencies. However, challenges such as sensitivity to heat, moisture, and the need for high-temperature processing hinder their long-term stability and commercialization. Traditional PSCs typically use electron transport layers (ETLs) alongside hole transport layers (HTLs) to...
