Abstract

Una estructura de celda solar de multiples capas incluye una apilamiento de capas semiconductoras de tipo-p y de tipo-n alternantes (10, 11, 12, 13, 14) instaladas para formar una pluralidad de uniones fotovoltáicas de rectificacion (15, 16, 17, 18). Se elaboran celdas de bajo costo a partir de material de baja calidad la cual se optimiza al emplear niveles de impurificacion muy elevados en capas delgadas. Típicamente, los niveles de impurificacion son mayores a 1017 átomos/cm3 y el grosor de las capas se relaciona con la longitud de difusion de la corriente portadora en grosor. Se hace contacto para soportar las capas por medio de una estructura de contacto subterráneo que comprende ranuras que se extienden por debajo a través de todas las capas activas, impurificándose las paredes de cada ranura (33, 34) con impurezas de tipo n o p dependiendo de las capas a las cuales éste por conectarse el contacto respectivo y rellenándose o llenándose parcialmente las ranuras con material de contacto metálico (31, 32).
