Device Performance of Emerging Photovoltaic Materials (Version 3)

Abstract

Following the 2nd release of the "Emerging PV reports," the best achievements in the performance of emerging photovoltaic devices in diverse emerging photovoltaic research subjects are summarized, as reported in peer-reviewed articles in academic journals since August 2021. Updated graphs, tables, and analyses are provided with several performance parameters, e.g., power conversion efficiency, open-circuit voltage, short-circuit current density, fill factor, light utilization efficiency, and stability test energy yield. These parameters are presented as a function of the photovoltaic bandgap energy and the average visible transmittance for each technology and application, and are put into perspective using, e.g., the detailed balance efficiency limit. The 3rd installment of the "Emerging PV reports" extends the scope toward triple junction solar cells.The ORCID identification number(s) for the author(s) of this article can be found under https://doi.org/10.1002/aenm.202203313.

Recent progress in layered metal halide perovskites for solar cells, photodetectors, and field-effect transistors

“…While organic–inorganic hybrid perovskite solar cells are promising emerging thin film photovoltaic technology, 53 they are sensitive to moisture and heat, thus hindering their applications. 54 For example, a small amount of a Lewis base, such as water (from rain and humid air), can disrupt the hydrogen bond, coordinate with metal cations, and dissolve the perovskite material in 3D perovskites, along with other phase-induced changes causing degradation.…”

Brief Outlook on Top Cell Absorber of Silicon‐Based Tandem Solar Cells

“…[178,179] Quaternary chalcogenides Cu 2 ZnSn(S, Se) 4 , (Ag, Cu) 2 ZnSn (S, Se) 4 are emerging materials and are considered to be the suitable replacement for toxic CdTe because of their environmentfriendly nature and Earth-abundant elements. [180,181] These materials have attracted attention for PV applications and in a short period have gained 13.6% PCE. [182] For Si-based tandem SCs, the implications are still limited but are striving toward higher PCE.…”

“…Many successful attempts show PCE of >23% for perovskite/CIGS tandem SCs. [ 181 ] As the top cell absorber for Si, CGSe has been employed due to the bandgap range from 1.65 to 1.85 eV, which is considered an ideal value. CGSe constitutes elements Cu, Ga, and Se, which are Earth abundant and reduce the cost constraint.…”

Prospects for Tin-Containing Halide Perovskite Photovoltaics

“…Over the past decade, the power conversion efficiency (PCE) of single-junction PSCs has surpassed 25%, for devices fabricated in both n-i-p (regular) and p-i-n (inverted) structures, on par with state-of-the-art crystalline silicon solar cells. , Further improvements to the efficiency of single-junction devices will become increasingly difficult as the field approaches the radiative efficiency limit. Tandem solar cells made by combining several absorbing layers in one device configuration offer a promising route to surpass the radiative efficiency limit for single-junction solar cells, increasing from 33% to 45% for tandems in an idealized theoretical scenario .…”
