Photo-voltaic (PV) devices such as a Dye-Sensitized Solar Cell (DSSC) is a source of energy that converts incident photon or solar radiation to usable electricity. DSSCs are fast becoming a viable and interesting alternative to the traditional inorganic photo-voltaic devices to address the demerits of the inorganic PV devices like the use of expensive noble metals and high-cost chemical synthesis processes. A DSSC functions with two main components, i.e., a photo-sensitizer that absorbs incident light and a semiconductor onto which it is adhered to and a conductive glass housing such as Florine-doped Tin Oxide (FTO) or Indium-doped Tin Oxide (ITO), between which the sensitizer, semiconductor and an electrolyte are sandwiched. The semiconductor is preferably a wide-band semiconductor, of which the commonly used semiconductors in a DSSC are made of a nanoparticle layer of Titanium dioxide (TiO2), Zinc oxide (ZnO) and Tin oxide (SnO2). The utility of these solar cells with a diverse number of natural photo-sensitizers for use as an alternative PV device is described. Currently, there are an abundance of natural sources that could be used to obtain photo-sensitizers from, such as, micro and macro algae, plants, bacteria, etc. leading to increased importance in renewable energy sector and has gained traction to be a viable renewable energy resource. In addition to the functioning of an organic DSSC, various characteristics of the pigments used as photo-sensitizers are described here. Patents filed regarding eco-friendly and natural Dye-Sensitized Solar Cells have been increasing as of late and holds substantial promise.

Background: Energy crisis is a vital issue worldwide and it will be increased tremendously in future. Alternative energy sources have been sought for the betterment of the future world. Solar energy is an alternative energy resource with plenty of opportunities. To make user- friendly and cheaper solar cells, dye-sensitized solar cells are tried to develop in this aspect. Objective: Single dye is not good enough to capture a wide range of solar light. The blending of different dyes is an alternative approach to harvest a wider range of solar lights on solar cells. Here, N719 and IR dyes were utilized to get UV-VIS and NIR ranges of solar lights in dye-sensitized solar cells. Methods: Dye-sensitized solar cells (DSSCs) were fabricated by using mixed dyes with various combinations of N719 (dye A) and IR dyes (dye B). The mixed dyes solutions were adsorbed on titanium dioxide (TiO2) and revealed significant light absorption & photosensitization compared with the individual dye solutions. The DSSCs fabricated with more percentage of IR dyes exhibited the best sensitization and broader spectrum. Results: The light absorption spectrum of the blended dyes solutions was confined peaks resultant of both N719 and IR dyes. The maximum efficiencies of 7.91% and 7.77% were obtained with 70% and 80% of IR dyes, respectively. Conclusion: Both N719 and IR mixed dyes solar cells were fabricated successfully for the first time. The relevant reasons behind the working of N719 and IR mixed dyes solar cells have been discussed. It was also noted that only IR dyes sensitized cells did not function under the simulated sunlight.

One of the considerations for renewable energy that can be accepted by society is energy based on nature (green future) and environmentally friendly (local wisdom). Dye-sensitized solar cells give to the world, easily and simple implemented technology for future renewable energy. This research was conducted by simulating the performance of DSSC using dye based on green future and local wisdom. Dye is one of the most important components influencing solar cell performance because dye determines the photoresponse of the DSSC. Several dyes that used in this research included Vasica nees, W. fruticose L, U. dioical L, R. arborium, Myrica nagi, Curcuma angustifiola dan Berberies aristate. The reason for this choice of dye included it is easily found in Indonesia, does not cause environmental pollution, and is thought to have good prospects to be applied to DSSC. The best performance results produced by DSSC are using dye W.fruticose L with an efficiency of 1.6%, and the lowest performance are using dye R. arborium with an efficiency of 1 %.

Our planet’s community largely depends on a snug energy supply, and non-renewable energy such as fossil fuel has been serving as the most trustworthy energy source from its discovery time of 1673 till to the current century. However, non-renewable energy resources are rapidly decreased per year due to increasing the energy consumption rate. To address this issue, renewable energy chiefly photovoltaic energy has attracted much though, because it directly converts solar energy into electrical without environment pollution. For the past several years, different photovoltaic devices like inorganic organic, and hybrid solar cells are invented for different application purposes. Regardless of its high conversion rate of silicon based solar cells, the high module cost and complicated production process restricted their application. Research has been focused on alternative organic solar cells for their inherent low module cost and easy fabrication processes. From all organic solar cells, Dye-Sensitized Solar Cells (DSSCs) are the most efficient, low cost and easily implemented technology. This review paper focus on clarifying the technological meaning of DSSCs, Types of DSSCs materials, working principle, advantages, power full applications area of DSSCs, the efficiency and challenges for R&D of DSSCs to upgrade the current efficiency.
