From band theory of solids, it is well known that electrical conductivity and optical transparency are mutually exclusive properties. However, due to advancement in science and technology, controlled doping has allowed to merge these properties in few materials such as thin films, bulk oxides, conducting polymers and carbon-based materials and are collectively known as transparent conducting oxides (TCO) and transparent conducting films (TCF). Recently, this extraordinary property is also found in doped nano-perovskites and hence can further meets the diversified demand in the field of photovoltaics, LCDs, FETs, diodes, supercapacitors and many more. For such applications, doped perovskite TCOs have becomes highly important and cost effective for the future global markets. This paper will summarize the status and progress of various TCOs which are particularly perovskite in structure. Future direction and challenges of doped Perovskites in the techno-era are also discussed. Several examples of TCO-Perovskites are presented with a discussion of their ferroic, magnetic, electrical and optical properties. On addition, the concerns related to thermal and chemical stability of TCO-Doped Perovskites are vividly reviewed.

The materials with high electrical conductivity σ and low thermal conductivity κ are the driving force for an efficient thermoelectric device. In general, electrical and thermal conductivity cannot be controlled independently as both electron and phonon participate in transport processes. Two dimensional layered materials are one such kind where van der Waals inter-layer interaction and covalent intra-layer bond favours strong phonon mediated electronic interaction. Here, we report that the substitutional p-type doping of WSe2 demonstrate negative correlation between σ and κ at wide temperature range from 5–300 K. Nominal 0.5% Nb doping of WSe2 (WSe2:Nb) increases the electrical conductivity by an order of magnitude and suppresses the thermal conductivity by the same magnitude. The formation of impurity band at close proximity (0.2 meV) of valance band display large delocalized carrier density and temperature independent mobility as compared to the undoped sample. Simultaneously, the strong delocalization of degenerate band impurity is also found to lower the thermal conductivity to 6 W m−1 K−1 at 300 K.
