This work explores the possibility of increasing the photovoltaic efficiency of InP semiconductors through a hyperdoping process with transition metals (TM = Ti, V, Cr, Mn). To this end, we investigated the crystal structure, electronic band and optical absorption features of TM-hyperdoped InP (TM@InP), with the formula TMxIn1-xP (x = 0.03), by using accurate ab initio electronic structure calculations. The analysis of the electronic structure shows that TM 3d-orbitals induce new states in the host semiconductor bandgap, leading to improved absorption features that cover the whole range of the sunlight spectrum. The best results are obtained for Cr@InP, which is an excellent candidate as an in-gap band (IGB) absorber material. As a result, the sunlight absorption of the material is considerably improved through new sub-bandgap transitions across the IGB. Our results provide a systematic and overall perspective about the effects of transition metal hyperdoping into the exploitation of new semiconductors as potential key materials for photovoltaic applications.

Current Scenario

: Perovskite-based photovoltaic technology has gained significant attention owing to its tunable electrical and optical properties. Among them, lead-based perovskites are considered as the most efficient one that delivers maximum power conversion efficiency with ample stability. In the current scenario, the perovskite-based solar cells (PSCs) can be classified into two main categories, i.e., highly efficient lead-containing and underperforming lead-free based. Even though lead-based PSCs delivers high efficiency, it loses the charm in the context of lead toxicity. The toxicity issue related to lead stands as a barrier to the commercialization of lead-based PSCs. To date, various materials have been prepared and implemented as an alternative to lead in the absorber layer. Tin (Sn) based perovskites are explored as an alternative absorber material owing to its photovoltaic properties that are comparable to lead. Tin-based perovskites exhibit some drawbacks, such as rapid crystallization, lack of oxidation stability, etc. Many research group has addressed the problems regarding tinbased perovskites and modified its structural and morphological aspects through compositional engineering as well as functional additives and managed to obtain an efficiency of around 10 %. In this review, we portray the state of the art developments of tin-based PSCs and its future perspectives.
