“…Presence of volatile elements causes the breakdown of CZTS which results in the formation of secondary phases which sometimes may be lost due to volatile nature. Some secondary phases formed will further react to form some other compounds [31,32]. The non-annealed samples synthesized at 45 kHz shows the presence of wurtzite and kesterite forms of CZTS [33][34][35].…”

Single-step ultrasound-assisted synthesis of Copper Zinc Tin Sulfide nanoparticles (CZTS) has been studied at two different frequencies. While the effects of frequency on the particle size of the CZTS nanoparticles were insignificant, a noticeable change was observed in composition. As-obtained particles presented the amorphous nature and spherical morphology with a high degree of agglomeration. Annealing of the synthesized CZTS nanoparticles increased the crystallinity while the sulfur content decreased considerably. The poly-dispersity and agglomeration of the nanoparticles increased upon annealing. The as-obtained CZTS nanoparticles synthesized at 45 kHz frequency presented a copper deprived and zinc-rich composition suitable for higher photo-conversion efficiency of the solar cells. The bandgap of the annealed and non-annealed particles ranged between 1.25 eV and 1.65 eV.

“…The first kesterite solar cell was built with vacuum techniques by Katagiri et al [8], showing a conversion efficiency of 0.66% in 1997 [8]; the current 12.6% record efficiency belonged to CZTSSe and was reported in 2014 [9]. Surprisingly, most of the record devices since 2009 have been made using a solution process for depositing the absorber film, contradicting the paradigm that the films deposited by wet chemistry generally generate lower performances compared to the similar ones deposited in vacuum [10]. Moreover, the non-vacuum technologies have the advantages of lowering the production costs and giving high uniformity of the final stoichiometry composition [5].…”

“…Above the AZO thin strips of Al or Ag / Al alloys are deposited which collect the current produced. Mo, ZnO and AZO are deposited by cathodic sputtering, while the aluminum contacts are made using a thermal evaporator[4,10]. Many of the defects at the interface between kesterite and adjacent materials are created during the annealing process, due to the inter-diffusion of the components.…”

The research on photovoltaics is focusing on developing solutions that involve the employment of abundant and non-toxic raw materials, along with simple production processes. Among the light-absorbing materials, which use earth abundant elements and are easily processable, there is the class of kesterite compounds. The efficiency record has been stopped at 12.6% for five years, but the research is fervent and dedicated to solving the limitations that make the device immature for the commercial market. The involvement and collaboration of researchers from multiple disciplinary areas are feeding the knowledge of this class of materials, promoting it as a possible next leader of the photovoltaic market.

“…Therefore, several research groups have studied fabrication of CuInSe2, CuIn(Se,S)2, and CIGS-based solar cells by electrodeposition [5]. So, several techniques have been developed to prepare CISSe thin film solar cells such as, mechanical milling [6], chemical bath deposition [7], evaporation [9], paste coating technologies [11], magnetron sputtering [11], microwave irradiation [12,13] and solvothermal method [14], electrodeposition [15], in order to improve their efficiencies. Some of these methods, in particular the chemical-based ones, have the advantages of simplicity, high throughput and inherent low investment requirements.…”

Annealing study of electrodeposited CuInSe2 and CuInS2 thin films

et al. 2018

In this study CuInSe2 and CuInS2 thin films were prepared onto ITO glass substrate using the electrodeposition technique in aqueous solution. The electrodeposited films were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive X-ray analysis (EDS). The annealing effects on electrodeposited precursors were investigated. The chalcopyrite structure of CuInSe2/CuInS2 showed an enhancement of crystallinity after subsequent selenization/sulfurization treatment in Se/S atmosphere, respectively. XRD and SEM studies revealed a dramatic improvement of the crystalline quality of CIS films after annealing treatments. Mott-Schottky measurements were used to assess the conductivity type of the films and their carrier concentration. The prepared samples underwent an etching process to remove the binary accumulated Cu2-x(Se,S) phases shown in FESEM pictures. This etching process has shown a noticeable decrease in both, the flat band potencial, Vfb (V), and the number of acceptors, NA (cm-3) in selenized CuInSe2 and sulfurized CuInS2 samples.
