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.

Solar cells can play a key role in the transition towards a sustainable future. This transition is one of the major challenges our society faces during the coming decades. Development of high-efficiency photovoltaic solutions at reasonable costs will help accelerating the transformation of our energy system. In this respect, perovskite solar...

Trap assisted tunneling modelling for aSi contact stacks in IBC-SHJ

Interdigitated back contact silicon heterojunction (IBC-SHJ) solar cells have demonstrated 26.6\% world record efficiency by combining outstanding passivation of Si thin film layers with the absence of front shading contact in the crystalline silicon (c-Si) absorber bulk. Furthermore, this type of solar cell merges advantages of c-Si with Si...
