High efficiency photovoltaic converter for high light intensities manufactured with optoelectronic technology

Abstract

The invention concerns photovolaic converters that work under high intensity light and provide high efficiency. Said converters generate photovoltaic electricity at low costs, which is a very interesting for the photovoltaic industry. They can be used in thermophotovoltaic systems and remote supply systems via optical fiber. The converter is characterized by the following features: a) its semiconductor layers are made of compounds III-V, b) photolithography is used to manufacture it and c) its size ranges from a few tenths to tens of square millimeters. Other optoelectronic techniques may be used for manufacturing such as wire welding, separation of the converters on one same wafer by sawing, point cutting and cleavage. Its design parameters are estimated by means of multivariable optimization. The situation in which the incident light has the shape of a cone and originates from a medium with any given refraction index is taken into account in the operating conditions.
