“…The performance of the same sensitizing dye in DSSC was achieved under the management of fill factor (FF), energy conversion efficiency (η), open-circuit voltage (Voc), and short-circuit current (Jsc). Many parts of a plant have been affected by differences in the dyes that belong to natural substances such as photosensitizers for DSSC [14]. Figure 2 shows the general molecular structure of anthocyanins.…”

“…The beetroot dye was not the main focus in either of the articles since each one uses a second dye to form the union. However, in the document [14], the use of purple cabbage as a second dye for their research is exposed and by combining it, an efficiency of 0.38% is obtained. On the other hand, the paper [15] presents spinach as a base for its second dye and reports an efficiency of 0.99% using 80% red dye and 20% green dye, in the combination of these two.…”

Human beings are attempting to take advantage of renewable natural resources by using solar cells. These devices take the sun’s radiation and convert it into electrical energy. The issue with traditional silicon-based solar cells is their manufacturing costs and environmental problems. For this reason, alternatives have been developed within the solar cell field. One of these alternatives is the dye-sensitized solar cell (DSSC), also known as Grätzel solar cells. DSSCs are a type of solar cell that mimics photosynthesis. They have a photoanode, which is formed by a semiconductor film sensitized with a dye. Some of their advantages include low-cost manufacturing, eco-friendly materials use, and suitability for most environments. This review discusses four important aspects, with two related to the dye, which can be natural or synthetic. Herein, only natural dyes and their extraction methods were selected. On the other hand, this paper discusses the nanostructures used for DSSCs, the TiO2 nanostructure being the most reported; it recently reached an efficiency level of 10.3%. Finally, a review on the novelties in DSSCs technology is presented, where it is observed that the use of Catrin protein (cow brain) shows 1.45% of efficiency, which is significantly lower if compared to Ag nanoparticles doped with graphene that report 9.9% efficiency.

Solar energy is the most promising sources of energy in KSA due to the constant high solar radiation throughout the year. This not used effectively due to the solar cells rising costs. Nano solar cells are the promising alternative in comparison to silicon solar cells due to its lower cost. leaves of green cabbage and orange plant used as sensitizers. The effect of extracted temperatures, and immersed periods on the energy conversion efficiency is obtained. Among the previous dyes, orange showed the best efficiency. The Nano dye sensitized solar cells (NDSSC’s) performance improved through controlling the extraction solution temperature and both the pre-treatments of the Nano zinc oxide glass substrate and its post-treatments films using hydrochloric, phosphoric, and nitric acids. The max. conversion efficiency is 0.141 at 60OC and 0.11 at 45OC for both orange and green cabbage respectively. The pre-treatment of the FTO with HCL, HNO3 and H3PO4 showed an efficiency improvement of 214%, 180% and 140% at 8 hrs using orange leaves dye, and 207%, 184% and 152% respectively at 6 hrs using green cabbage .
