Optimization of Three-terminal Perovskite/Silicon Tandem Solar Cell Using Opto-electrical Simulations in TCAD Sentaurus

Perovskite/Silicon tandem cells are gradually becoming more promising in the field of photovoltaic technology since they have already surpassed the theoretical power conversion efficiency (PCE) limit of single junction (SJ) silicon cells (~30%), while they can be commercially compatible. Several architectures of Perovskite/silicon devices were...

Broadening the Thin-Film Horizon: Opto-­electrical modelling of a monolithic Perovskite/CIGS tandem solar cell

The need for more efficient, cheaper, easily producible solar cells is growing as this combination of attributes can decrease the levelized cost of energy (LCOE). A two­terminal (2T) Perovskite and galliuminidium­gallium­selenide (Pvk/CIGS) tandem cell is an excellent candidate, as it can have a power conversion efficiency (PCE) of +30%, can be...

Electrical Simulations of Perovskite/c-Si Tandem Solar Cells

Within the PVMD group at TU Delft, the study of perovskite/c-Si tandem solar cells is being researched. A comprehensive study is performed through advanced optical and electrical simulations to understand the tandem’s characteristics and operative behavior. We use GenPro4 and Sentaurus TCAD to perform the optical and electrical simulations,...

Opto-electrical simulations of perovskite/c-Si tandem solar cells

Due to the high-efficiency potential over 40%, the two-terminal (2T) perovskite/c-Si tandem solar cell becomes a desirable and promising candidate for solar cells. The photovoltaic materials and devices (PVMD) group in TU Delft has developed the c-Si solar cell using poly-SiOx as carrier-selective passivating contacts. The utilization of poly...

Interdigitated back-contacted structure: A different approach towards high-efficiency ultrathin copper indium gallium (di)selenide solar cells

An interdigitated back-contacted (IBC) configuration is proposed for submicron copper indium gallium (di)selenide (CIGS). In a modelling platform, the structure was opto-electrically optimized for maximum efficiency. The results are compared with a reference front/back-contacted (FBC) solar cell with similar absorber thickness and exhibiting...

Strategy to mitigate the dipole interfacial states in (i)a-Si:H/MoO_x passivating contacts solar cells

Molybdenum oxide (MoO_x) is attractive for applications as hole-selective contact in silicon heterojunction solar cells for its transparency and relatively high work function. However, the integration of MoO_x stacked on intrinsic amorphous silicon (i)a-Si:H layer usually exhibits some issues that are still not fully...

Electrical Modeling of Perovskite Solar Cells

High-performance perovskite solar cells (PSCs) have attracted great attention from researchers around the world. Rapid researches and developments of PSCs are shown by the increase of its efficiency from 3.8% in 2009 to a new world record of 22.4% in 2017. Hysteresis phenomenon in current density voltage (J-V) is one of the challenges occurring...

Light management in thin-film silicon solar cells

Solar energy can fulfil mankind’s energy needs and secure a more balanced distribution of primary sources of energy. Wafer-based and thin-film silicon solar cells dominate todays’ photovoltaic market because silicon is a non-toxic and abundant material and high conversion efficiencies are achieved with silicon-based solar cells. To stay...
