“…It is a process in which substrate is placed in a hot chemical solution stirring vigorously for specific time, positive and negative ions will reach and meet on the substrate and thin film is grown. The advantage of this technique is that neither vacuum and nor very high temperature is required for CBD [5,21].…”

“…Hence, a variety of methods have been applied for the synthesis of such materials, e.g., thermal evaporation [16], chemical pyrolysis deposition (CPD) [17], metal organic chemical-vapor deposition (MOCVD) [18][19][20], closed space sublimation (CSS) [21] and chemical bath deposition (CBD) [22][23][24][25]. CSS and CBD are known to produce optimal and encouraging results for CdTe/CdS based solar cells.…”

“…CdS is used as a window layer; it means more than 70% of light will pass through the first n-type layer of solar cells. Different techniques can be used for the manufacturing of thin film CdTe based solar cells [19][20][21][22][23][24][25][26]. It has some native defect cation vacancies (Vcd) that can behave as double accepters and anion vacancies (VTe) can behave as double donors.…”

We report CdTe, CdS, and ITO thin films on glass substrates for solar cell fabrication by closed space sublimation and chemical bath deposition. CdTe and CdS thin films were sublimated to chemical treatment at 25°C in a saturated CdCl 2 solution (1.04 g/100 ml methanol) and heat treated at 400°C for 30 minutes. Indium tin oxide and tellurium films were analyzed by spectrophotometer and scanning electron microscopy. It has been observed that solar cell performance can be improved by depositing a CdCl 2 layer on the CdTe/CdS layers. The optical, structural, and morphological changes of CdTe and CdS surfaces on CdTe/CdS/ITO/glass solar cells due to CdCl 2 solution treatment followed by annealing for 400°C were studied. Optical analysis showed about 15% decrease in transmittance after CdCl 2 heat treatment in case of CdTe thin film, whereas CdS thin film demonstrated an increase of about 10-15% transmittance after CdCl 2 heat treatment. Similarly, a decrease in band gap values was found for both CdTe and CdS thin films after CdCl 2 heat treatment. XRD and SEM results of CdCl 2 heat-treated CdTe and CdS samples showed recrystallization, reorientation, and progressive increase in grain size. The grain sizes of CdTe and CdS samples demonstrated an increase of about 0.2 µm.

Abstract. We present an innovative back contact for CdTe solar cell by the application of a transparent conducting oxide, typically ITO, as a back electrical contact on CdTe/CdS photovoltaic devices that acts as a free-Cu stable back contact and at the same time allows to realize bifacial CdTe solar cells, which can be illuminated from either or both sides. The controlled insertion of a very limited amount of copper into the ITO back contact permits to have reproducible devices with high efficiencies still keeping the bifacial configuration. Thin CdTe layer solar cells with ITO back contact have been realized with efficiencies exceeding 10%, the reduced thickness of CdTe allows to have a better performance on the back-side illumination and reduces the amount of CdTe material.
