Understanding the Implication of Carrier Diffusion Length in Photovoltaic Cells
The purpose of this Viewpoint is to dispel a commonly held misconception when comparing diffusion lengths and discuss how variation in the measuring techniques can bring about differences in the measured values. The diffusion length, L d, of electrons or holes in a semiconductor is defined by the average distance the relevant charge moves in the …
Degradations of silicon photovoltaic modules: A literature review
The thickness of silicon PV cells decreased from 300 μm to less than 200 μm and sometimes to less than 100 μm. In addition to the reduction in thickness of PV cells, the cell surface increased to 210 mm × 210 mm (Dallas et al., 2007). This makes PV cells
Photovoltaic (PV) Cell: Working & Characteristics
Photovoltaic (PV) cells, or solar cells, are semiconductor devices that convert solar energy directly into DC electric energy. In the 1950s, PV cells were initially used for space applications to power satellites, but in the 1970s, they began also to be used for terrestrial

Potential-induced degradation in perovskite/silicon tandem photovoltaic modules
Applying a −1,000 V voltage bias to perovskite/silicon tandem PV modules for 1 day causes potential induced degradation with a ∼50% PCE loss, which raises concerns for tandem commercialization. During such testing, Xu et al. observe no obvious shunt in silicon subcells but degradation in perovskite subcells caused by the diffusion of …
