Combined Fabrication and Performance Evaluation of TOPCon Back-Contact Solar Cells with Lateral Power Metal-Oxide-Semiconductor Field-Effect Transistors on a Single Substrate

Nowadays, an increasing share of photovoltaic (PV) systems makes use of module- or submodule-level power electronics (PE). Furthermore, PE is used in stand-alone devices powered by PV-storage solutions. One way to facilitate further implementation of PE in PV applications is to integrate PE components into crystalline silicon PV cells. Herein...

Revealing capacitive and inductive effects in modern industrial c-Si photovoltaic cells through impedance spectroscopy

To achieve a high performance in sub-module power conditioning circuits, it is important that power converters are designed in accordance with the photovoltaic (PV) cell impedance at the input. Taking this one step further, exploiting the impedance of cell strings could even support novel power conditioning approaches in PV modules. In this...

Exploring the benefits, challenges, and feasibility of integrating power electronics into c-Si solar cells

Power electronics traditionally plays a crucial role in conditioning the power of photovoltaic (PV) modules and connecting the systems to the electricity grid. Recently, PV module designs with more sub-module power electronics are gaining increased attention. These designs can offer higher reliability and improved resilience against non...
