A semiconductor component (50), in particular a solar cell, which has at least one semiconductor base material (40) consisting of a mono or a polycrystalline structure. The semiconductor base material (40) consists at least in part of pyrite with the chemical composition FeS2 and which is cleaned for the purpose of achieving a defined degree of purity. Maximum benefit is drawn from the semiconductor base material (40) when it is produced from at least one layer of pyrite (51), at least one layer of boron (52) and at least one layer of phosphorous (53). An optimum type is derived from this semiconductor component when it is used as a solar cell.

L'invention concerne un composant à semi-conducteur (50) se présentant en particulier sous forme de pile solaire, qui comporte au moins un matériau de base à semi-conducteur (40) comprenant une structure mono- ou polycristalline. Le matériau de base à semi-conducteur (40) se compose au moins en partie de pyrite avec la composition chimique FeS2, qui est purifiée pour obtenir un degré de pureté défini. Le matériau de base à semi-conducteur (40) se compose très avantageusement d'au moins une couche de pyrite (51), d'au moins une couche de bore (52) et d'au moins une couche de phosphore (53). Ce composant à semi-conducteur permet d'obtenir une réalisation optimale, notamment s'il est utilisé comme pile solaire.
