Photovoltaic Characterization

Photovoltaic technology has a range of applications nowadays. Organic solar cell research has developed in recent years.  Common materials for organic solar cells are phthalocyanines. In this paper it is presented a discussion of the fundamentals of photovoltaic technology, photovoltaic effect, organic solar cells, phthalocyanines and Gallium Arsenide reconstructed surfaces. Also it is studied the behavior of lead pthalocyanine (PbPc) in substrates of Gallium Arsenide-GaAs (001) with reconstruction surface Arsenide (As) stoichiometric β2(2x4). It is an analysis and study of innovative organic solar cells. The reason for this study is that PbPc is an organic molecule with very good optoelectronic properties, promising to be used in organic thin film solar cells or combination of organic and inorganic layers solar cells. In research is the behavior of phthalocyanines according to the surfaces of the substrates. The experimental photovoltaic characterization of a solar cell from lead phthalocyanine is presented.  The efficiency of potential solar cells is estimated by measuring the photocurrent spectra. The understanding of the material and the samples combinations is important for potential applications and improvements for the use of solar cells.

AzaBenzannulated PDI (AzaBPDI) dyes were synthesized in high yields via a new reaction sequence involving an imine condensation followed by visible light-induced photocyclization. The large scope and efficiency of this alternative to the Pictet-Spengler reaction is demonstrated, and allows the easy preparation of dimeric AzaBPDI as potential non-fullerene acceptors for organic solar cells.

The Way

The electrophilic borylation of 2,5-diarylpyrazines results in the formation of boron-nitrogen doped dihydroindeno[1,2-<i>b</i>]fluorene which can be synthesized via mildly air-sensitive techniques and the end products handled readily under atmosphereic conditions. Through transmetallation via diarylzinc reagents a series of derivatives were sythesized which show broad absorption profiles that highlight the versatility of this backbone to be used in organic solar cell devices. These compounds can be synthesized in large yields, in alow number of steps and functionalized at many stages along the way providing a large depth of possibilities. Exploratory device paramaters were studied and show PCE of 2%.
