Perovskite Photovoltaic Minimodules: Performance Predictions

The monolithic module design is a suitable solution to upscale the lateral dimensions of perovskite solar cells. The device's active area is divided into smaller cells with an interconnection gap. The narrower the subcell, the lower the resistance of each subcell with consequent improvement of the FF. However, the interconnecting gap between each subcell is an inactive area, that reduces the total efficiency of the module. The interconnection is composed of lines P1, P2, and P3, which respectively separate the TCO, the photoactive layer, and the top contact between consecutive subcells.

We used the simulation software Laoss to optimize a perovskite photovoltaic minimodule. This procedure can replace the standard experimental trial-and-error approach that is commonly used to upscale perovskite solar cells.

Grid geometry optimization to maximize the efficiency of large-area organic devices

It is challenging to increase the device area of optoelectronic devices based on perovskite and organic materials without losing performance. One of the key issues is the high sheet resistance (Rs) of the transparent conductive oxide (TCO). Combining the TCO with a metallic grid reduces the ohmic losses, but what is the grid geometry that maximizes performance?

In this tutorial, we will show you, how to use the simulation software Laoss and its optimization feature to quickly find the grid geometrical features for maximum power output.

Electro-Thermal Modeling of Thin-Film Solar Cells with LAOSS

Our 2D + 1D software LAOSS is a perfect tool to understand and improve on different upscaling strategies which combine 1D layer stack with 2D lateral simulations. In this blog post, we will discuss the findings by Matthias Diethelm and his colleagues who used LAOSS to simulate centimeter-sized organic solar cells to understand loss channels and macroscopic defects.

Optimize Micro-Textures for Increased Light Extraction in Flexible, Curved Displays

Flexible electronics have been envisioned to change the way we interact with technology. Flexible circuit boards are already ubiquitous. These applications of flexible electronics are packaged away inside electrical gadgets and instruments and are therefore not visible to the end user. Nevertheless the development of this technology allowed for tighter packed and therefore smaller and still powerful devices. Curved displays are an application of flexible electronics where the user directly interacts with the shaped object and the technological advancement is directly tangible for the end user.
