Resumen

Una nueva molécula, 2TPA-SP, aumenta el rendimiento y la estabilidad de las células solares de perovskita (PSC) al mejorar el contacto interfacial y la pasivación de defectos. Esto conduce a mayores eficiencias de conversión de energía (PCE) y fiabilidad operativa a largo plazo para la próxima generación de sistemas fotovoltaicos.

P-N junction

A p-n junction is formed when p-type and n-type semiconductor materials are joined together. At the interface of the p-n junction, holes from the p-side and electrons from the n-side begin to diffuse into the opposite sides due to the concentration gradient. This diffusion of carriers leads to a region around the junction where there are no free charge carriers, known as the depletion region. The charge density within the depletion region for the n-side and p-side can be described by the...
