This parameter is designed as a catch-all for any form of inefficiency internal to or around a system that manifests as a harmful effect on something around the system.  Can also mean any form of pollutant or environmental emission generated by a system or object.  This is a derivative of the 'loss of substance' definition above, the focus however is on "harmful emissions" this aspect is on the production of chemicals, etc. that was not one of the original substances contained within the system.

The system involves converting metals into halide perovskites (HaP) for solar applications.The primary metals used are lead, gold, and copper: Lead is initially tested for conversion into methylammonium lead iodide (MAPbI3), while gold and copper are considered safer alternatives. Chemical solutions such as methylammonium iodide (MAI) are used in various concentrations (25mM, 50mM, 250mM) along with additives like iodine (a free halogen), trifluoroacetic acid (TFA), and sodium hydroxide (NaOH). Two main conversion techniques are employed: <ol><li>dipping, where metal films are immersed in salt solutions, </li><li>spin coating, an alternative method for creating thin films.</li></ol> Characterization methods include X-ray diffraction (XRD) for analyzing diffraction patterns, scanning electron microscopy (SEM) for imaging, energy-dispersive X-ray spectroscopy (EDS) for compositional analysis, and photoluminescence (PL) and time-resolved photoluminescence (TRPL) for studying optical properties and carrier lifetimes. The system aims to efficiently and reproducibly convert metals like gold and copper into halide perovskites, reducing toxicity and enabling the production of efficient and environmentally friendly solar cells. Challenges include toxicity (especially with lead), ensuring reproducibility, and producing small, uniform crystals by controlling chemical parameters and reaction times.

✔️ Effective Brainstorming

The system we are analyzing involves the conversion of metals such as lead, gold, and copper into halide perovskites for solar applications. This process includes depositing metal films on substrates using techniques like magnetron sputtering and spin coating. These films undergo chemical reactions with methylammonium bromide (MABr) in various solvents under controlled conditions. The resulting perovskite films are characterized using methods like XRD, SEM, EDS, PL, and TRPL. The aim is to optimize parameters like MABrconcentration, reaction time, and the addition of halogens to produce stable, efficient, and reproducible perovskite films for solar cells while addressing challenges related to toxicity, cost, and process complexity.
