In many technological applications the mankind mimics the nature. One of the excellent examples is photosynthesis. The knowledge of the natural photosynthesis mechanisms is extremely useful in understanding of molecular processes occurring in photovoltaics. In this review article the photophysical fundamental aspects of photosynthetic units are presented. The similarity and dissimilarity between photosynthesis processes and photovoltaic ones is also shown. This paper is based first of all on the results of the investigations of corroles and corrole-fullerene dyads. The results of spectroscopic examinations supported by chemical calculations are presented.
