Summary Transition metal oxides/silicon heterocontact solar cells are the subject of intense research efforts owing to their simpler processing steps and reduced parasitic absorption as compared with the traditional silicon heterostructure counterparts. Recently, molybdenum oxide (MoOx, x < 3) has emerged as an integral transition metal oxide for crystalline silicon (cSi)‐based solar cell based on carrier‐selective contacts (CSCs). In this paper, we physically modelled the CSC‐based cSi solar cell featuring MoOx/intrinsic a‐Si:H/n‐type cSi/intrinsic a‐Si:H/n+‐type a‐Si:H for the first time using Silvaco technology computer‐aided design simulator. To analyse the optical and electrical properties of the proposed solar cell, several technological parameters such as work function and thickness of MoOx contact layer, intrinsic a‐Si:H band gap, interface recombination, series resistance, and temperature coefficient have been evaluated. It has been shown that higher work function of MoOx induces the formation of a favourable Schottky barrier height as well as an inversion at the front interface, stimulating least resistive path for holes. Utilising thinner MoOx layer implies reduced tunnelling of minority charge carriers, thus enabling the device to numerically attain 25.33% efficiency. With an optimised interface recombination velocity and reduced parasitic absorption, the proposed device exhibited higher Voc of 752 mV, Jsc of 38.8 mA/cm2, fill‐factor of 79.0%, and an efficiency of 25.6%, which can be termed as the harbinger for industrial production of next‐generation efficient solar cell technology.

“…Another perspective discussed by Rahman et al was the examination of the interaction between electrons and phonons in pyrite-based solar cells . Chen et al noted that the electron–phonon coupling and impurity scattering arising from doping are two main sources of energy loss in photovoltaics and play a vital role in determining the efficiency . This employs that more studies could be conducted studying the effect through Raman spectroscopy, which is an excellent tool in extracting information regarding coupling strengths of electron–phonon interactions …”

With an increase in energy demand and the depletion of conventional fuels, solar cells are emerging as an excellent alternative, providing a sustainable and clean source. Solar cells consisting of different materials have been introduced in recent years, and the overall performance defined by these materials has a lot of potential to increase. Transition metal dichalcogenides have gained significant importance due to their advantageous properties and promising potential. Iron disulfide or pyrite is one such material that has risen as a favorable material for photovoltaics cells owing to its suitable band gap, high absorption coefficient, and low cost. Not only this, the “earth abundance” and nontoxicity have also increased its prospects as a photovoltaic material. This study aims to review recent progress on the synthesis of pyrite and its utilization in photovoltaics. Different methods used for the synthesis of pyrite are reviewed followed by the properties of pyrite, the challenges that hinder its efficiency, and the possibilities of further research in this area.

“…One of the techniques for achieving a low production cost is the use of screen-printed electrodes for IBC crystalline silicon solar cells. [11][12][13][14] Among these cells, the bifacial IBC solar cell has the potential to show high output because the bifacial cell concept enables light to be absorbed on both sides of the cell. [15][16][17] The Mercury IBC cell developed by ECN and the ZEBRA cell by ISC Konstanz show high bifacial factors of 0.83 and 0.74, respectively.…”

N-type bifacial interdigitated-back-contact (IBC) crystalline silicon solar cells were processed with screen-printed electrodes. The bifacial IBC cells resulted in a drastic decrease of the electrical shading loss at the finger region with decreasing pitch on the rear side. This loss was dominated by the width of the base region. In addition, passivation properties also affected carrier recombination in the base region. A narrower base region and smaller pitch led to higher internal quantum efficiency and low series resistance. Cell efficiency of over 22% was obtained for the bifacial IBC crystalline silicon solar cells with a base region width of 250 μm and pitch of 1250 μm. The IQE values above the emitter and base region at medium wavelengths were over 95% and 90%, respectively. Using these cells, a mini-module showing 19.4% module efficiency with 78.1% FF was created.
