Optimization of Three-Terminal Perovskite/Silicon Tandem Solar Cells

We use simulations to optimize perovskite/silicon tandem solar cells in a novel three-terminal configuration, with one terminal at the front and two at the rear. We consider configurations in which the top cell has either the inverted or the same polarity as the bottom cell. Our goal is to minimize the optical losses, to compare the...

Combination of Advanced Optical Modelling with Electrical Simulation for Performance Evaluation of Practical 4-terminal Perovskite/c-Si Tandem Modules

The perovskite solar cell is considered a promising candidate as the top cell for high-efficiency tandem devices with crystalline silicon (c-Si) bottom cells, contributing to the cost reduction of photovoltaic energy. In this contribution, a simulation method, involving optical and electrical modelling, is established to calculate the...

Optical modeling of thin-film silicon solar cells with submicron periodic gratings and nonconformal layers

In thin-film silicon solar cells (TFSC) efficient light management is essential in order to increase energy conversion efficiency. The application of nano-scale periodic gratings (PG) is a promising method to enhance absorption in the absorber layers of TFSC since they can efficiently scatter the incident light. Carefully designed gratings give...

Novel H2 manufacturing routes. Simulation and thermodynamic analysis of membrane based processes

Nowadays hydrogen is gaining more and more attention mainly because it is generally regarded as an important future fuel. Although H2 can be produced from a wide variety of resources using a range of different technologies, natural gas is generally preferred and will remain in the near future the major feedstock for the manufacture of H2....
