An overview on the role of ZnTe as an efficient interface in CdTe thin film solar cells: a review

Abstract

Solar energy may cater current power demand and second generation with modified technologies could play important role. This review presents role of ZnTe as efficient interface to CdTe devices with future road map to improve device performance.

Cyclotriguaiacyclene-functionalized trans-cinnamic acid with alkyl arms: an efficient supramolecular system for solar cell and liquid crystalline applications

“…Such thin films can be employed as optical window in CdTe based solar cell devices to augment perfornace together with environment aspects as the prevalent CdS optical window material is a known toxic compound while one needs to ensure required properties in analogy to the champion CdS layer. 8,48 There are some reports in the literature where supramolecular LCs are used in various solar cell devices to acquire higher efficiency. Levitsky et al reported a solar cell based on n-type nanoporous Si (PSi) filled with copper Pc (CuPc).…”

“…So far cadmium-based materials with a wide energy band gap are used to transmit the maximum level of incident light to the respective absorption layer in solar cells. 7,8 In CdTe based solar cells, CdS is widely used in the window layer preparation. However, due to the carcinogenic properties of this compound there is a need to have an alternative window material that should possess desired properties in view of CdS applicability so far.…”

A ternary system exploiting the full solar spectrum to generate renewable hydrogen from a waste biomass feedstock

“…20,25,26 PVT collectors based on spectral beam splitting 27 allow the solar cells and the thermal receiver to operate at significantly different temperatures, preventing excessive de-rating of the cells' efficiency while also generating medium to high temperature heat (4100 1C). Furthermore, emerging PV materials (e.g., cadmium telluride (CdTe), perovskites and copper indium gallium diselenide (CIGS)) are now attaining high power conversion efficiencies of up to 23%, 28 and have been demonstrated to work as semi-transparent top-cells in multi-junction configurations. 29 To-date, the implementation of semi-transparent PV solar cells as selective beam splitting filters is limited despite offering a means to efficiently utilise the full solar spectrum.…”
