The photogalvanic cell is mimic process of photosynthesis. The net conversion efficiency of photosynthesis is ~5.6% when quantum yields; dark media, photorespiration and absorption coefficient took in consideration . This value seems very low but it represents conversion of solar energy into chemical (stored) energy.
The results of electrical parameters (open circuit potential, short circuit current, power at power point, fill factor, conversion efficiency and storage capacity) of the photogalvanic cells containing dye, reductant and surfactants have given in a tabular form with comparison of more than 150 systems.
The VOC is mainly depending on the adopted process of manufacturing solar PV cell and temperature however, it has no influence of the intensity of incident light and surface area of the cell exposed to sunlight. Most commonly, the VOC of solar PV cells has been noticed between 0.5 and 0.6 V.
In this review we have proposed suitable classification of solar cell based on the excitation (direct or indirect) of electron and semiconductor used, in which the photogalvanic cell has potential to revolutionize the existing solar cells due to its low cost and inherent storage capacity.
