“…5(b). 48,49,65 In contrast to common oxides, CZTS, as a direct band gap semiconductor, has the band gap energy of ∼1.4-1.5 eV and is close to the optimal band gap energy of 1.45 eV. In addition, CZTS has a high absorption coefficient >10 4 cm -1 along with intrinsic p-type conductivity of CZTS also makes it a suitable CE due to the fast transfer of photo-generated holes and further efficiency.…”

A contribution of counter electrode (CE) emphasis a great impact towards enhancement of a dye-sensitized solar cell's (DSSC) performance and Pt based CE sets a significant benchmark in this field. Owing to cost effective noble metal, less abundance and industrial large scale application purpose, an effective replacement for Pt is highly demanded. There are several approaches to improve the performance of a CE for enhancing the power conversion efficiency with a less costly and facile device. To address this issue, reasonable efforts execute to find out suitable replacement of Pt is becoming a challenge by keeping the same electrochemical properties of Pt in a cheaper and eco-friendlier manner. With this, cheaper element based quaternary chalcogenide, Cu2ZnSnS4 (CZTS) becomes a prominent alternative to Pt and used as a successful CE in DSSC also. This review presents brief discussion about the basic properties of CZTS including its synthesis strategy, physicochemical properties and morphology execution and ultimate application as an alternative Pt free CE for a low cost based enhanced DSSC device. It is therefore, imperative for engineering of CZTS material and optimization of the fabrication method for the improvement of DSSC performance.

“…Recently, extensive research has focused on developing alternative alloy-based materials for low-cost and effective CE. [3][4][5][6][7][8][9][10][11] The bimetallic configurations of alloy-based CE offer many synergistic effects which directly affect their catalytic activity, including tunable electronic structures and materialspecific ensemble effects. 12 Among them, Pt-based alloys have drawn considerabe attention, including PtAu, PtCo, PtRu, PtFe and PtSn alloys.…”

“…One promising method of improving the efficiency/price ratio is to replace the conventional materials with cheaper alternatives and to reduce the manufacturing cost while maintaining the state-of-the-art device efficiency. 5 The counter electrode (CE) is a crucial component of DSCs and functions as a catalyst in the regeneration of iodide from triiodide ions. The high electrical conductivity, long-term stability, excellent catalytic activity, and low fabrication cost of CEs are key requirements for the development of highly efficient DSCs.…”

“…A solar cell, SC, consists of a junction of p-and n-type semiconductors. At the interface the Fermi levels of both semiconductors are the same, generating depletion region, and therefore, a charge separation [10]. When photons are absorbed in the p-type region, an electron-hole pair is created [11].…”

A Titanium Dioxide-Roselle Dye sensitized solar cell with a dimension of 20 x 20 mm was fabricated using Doctor-Blade Method. Some of the samples were given annealing treatment at various temperatures of 250 0 C, 300 0 C, 350 0 C, 400 0 C and 450 0 C respectively with same annealing time of 30min. The device under test (DUT) were tested using a Kiethley 2400, source meter under A.M 1.5 (1000W/m 2 ) illumination from a Newport class A solar simulator. The results shows that at the various annealing temperatures, the open circuit voltage V oc = 0.091V, 0.79V, 0.78, 0.93 and 0.46V, the short circuit current density J sc =42µAcm -2 , 16µAcm -2 , 109µAcm -2 , 505µAcm -2 and 8µAcm -2 , the fill factor FF= 0.15, 0.06, 0.03, 0.02 and 0.14 and the energy conversion efficiency, η = 6 x10 -4 , 8 x10 -4 , 2 x10 -3 , 6 x10 -3 and 5 x10 -4 respectively. The best results of open circuit voltage V oc =0.93, short circuit current density J sc = 505µAcm -2 , fill factor FF= 0.02 and energy conversion efficiency η= 6 x10 -3 was at temperature T= 400 0 C at constant annealing time, t =30 minute compared to the other four samples annealed at temperatures 250 0 C, 300 0 C, 350 0 C and 450 0 C. These results shows that at temperature T= 400 0 C the annealing treatment shows some effects on the electrical properties of the TiO 2 -Roselle Dye Sensitized solar Cell produced.Copy Right, IJAR, 2016,.

Introduction:-A solar cell is an electronic device which convert direct solar energy into electricity using the process called photovoltaic effect. The process is achieved by shining light on the solar cell which creates an electrical current or voltage in the material that generate an electric power. Solar cell is becoming ever important as an alternative sources of energy that are both cheap, efficient and environmental friendly [1]. Compared to the fossil fuels -coal, oil, and natural gas, which were formed millions of years ago from the fossilized remains of plants and animals and are the main sources of energy today [2]. Based on the depletion of fossil fuel and the environmental hazards that it causes, the use of solar energy is certainly one of the most viable ways to solve the world's energy crisis [3]. More also, owing to the rapid consumption of conventional sources of energy through high demand despite their consequences due to pollution, solar energy is considered as promising alternative to the forecasted energy and societal challenges [4]. Renewable energy sources such as solar energy are considered as a practicable alternative because "More energy from sunlight strikes Earth per each hour than all of the energy consumed by humans in an
