Double POLO Carrier Selective Contact Based PERC Solar Cell for 25.5% Conversion Efficiency: A Simulation Study

Abstract

Polycrystalline Silicon on Oxide (POLO) passivating contacts have emerged as a carrier selective contact for high-efficiency Si-based photovoltaic (PV) devices. In this paper, double POLO PERC (Passivated Emitter and Rear Contact) device is designed by employing POLO contacts on both contact sides to reduce the contact recombination losses through Silvaco-TCAD tool. The performance of the double POLO PERC device has been studied by using the PV parameters and current-density (J-V) curve. The impact of tunnel oxide thickness variation (1 nm, 1.25 nm, 1.5 nm) in the tunnel oxide layer is also analyzed. The performance of textured double POLO PERC solar cell is optimized at 1.5 nm thickness (TOX), which reflects optimum conversion efficiency of 25.5%. Reported study of double POLO PERC device may open up a door for further improvement in PERC device performance.

Performance enhancement of CsPbI3-xBrx perovskite solar cells via graded bandgap and affinity engineering

“…At present, the majority of the world's energy requirements are met by fossil fuel-based sources, but their reserves are depleting at an accelerated rate due to increased energy consumption. To overcome these challenges and meet the increasing energy demands, it is necessary to develop sustainable energy options [9][10][11][12]. Among these, renewable energy resources i.e., solar energy offer a solution to tackle this substantial demand without inflicting harm on our planet and harnessed through photovoltaic (PV) cells for direct electricity conversion stands out as the most abundant renewable energy source [13][14][15][16][17][18].…”

Field studies of PERC and Al-BSF PV module performance loss using power and I-V timeseries

“…The similar architecture between PERC and Al-BSF allows PERC to be integrated into industrial Al-BSF workflows without much disruption. Many efforts have been made to increase the cell efficiency of PERC (Kashyap et al, 2022a;Kashyap et al, 2022b;Kashyap et al, 2022c;Kashyap et al, 2022d;Kashyap et al, 2022e). Also, PERC cells are able to be made bifacial (Deline et al, 2019).…”
