Perovskite solar cells (PSCs), which developed from dye sensitized solar cells (DSCCs), have piqued the curiosity of the whole international scientific community since their inception in 2009. Some perovskites such as methylammonium, formamidinium and cesium lead iodide perovskites have emerged as exceptional options for decreasing the active layer thickness of photovoltaic systems to a few hundred nanometers for achieving solar conversion efficiency (PCE) of over 25%. The current focus is therefore on utilizing this novel and extremely promising class of materials in solar cells to improve their performance and ensure long-term stability. In order to clinch this goal, the research at AMDL is emphasized on molecular engineering of novel 3D/novel hybrid perovskite compositions, modifying their properties by applying different organic components, or designing two-dimensional (2D) and hybrid 2D/3D perovskite materials that can add to the stability of PSCs without reducing their remarkable photovoltaic capabilities.

Organic solar cells (OSCs) are one type of photovoltaic (PV) devices generating electricity by a layer made of a blending of donor and acceptor organic materials by collecting sunlight. As promising new PV technology, OSCs have a lot of potential because they are environmentally safe, flexible, lightweight, and exhibit affordable construction facilities. OSCs are manufactured from organic solvents using a solution processing technique by varying the kind of donor and acceptor small organic electronic materials, hole and electron transport layer, or metal electrode. Nowadays, AMDL is focused on designing and synthesis of novel and effective small organic electronic materials in large-scale with low-cost processes for high performance and stable OSCs.
