What is a high-efficiency polycrystalline silicon PV cell?

High-efficiency (18.1%) polycrystalline silicon cells fabricated using 100 μm-thick wafers were reported by Sharp in 2009 23. The electrical performance of crystalline silicon PV cells with the standard back surface structure of an aluminum-alloyed BSF decreases as the substrate becomes thinner.

What is the synergy between silicon-based semiconductor devices and PV cells?

The synergy of technologies and equipment developed for other silicon-based semiconductor devices, such as large-scale integrated circuits and the many different kinds of silicon semiconductor applications, with those developed for PV cells supported progress in both fields.

How efficient are crystalline silicon photovoltaic cells?

The efficiency of crystalline silicon photovoltaic cells had reached the threshold of 25% about two decades ago, on a laboratory scale. Despite all the technological advances since then, currently, the peak efficiency increased very marginally to the level of 26.6%.

Can recycled semiconductor material be used in crystalline silicon photovoltaic modules production?

The use of recycled semiconductor material in crystalline silicon photovoltaic modules production - A life cycle assessment of environmental impacts. Sol. Energy Mater. Sol. Cells 2020;205:110259. Doni A, Dughiero F. Electrothermal heating process applied to c-Si PV recycling, in: 38th IEEE Photovoltaic Specialists Conference (PVSC) 2012: 757–62.

What happens if a PV module is partially shaded?

And under partial shading, not only the efficiency of the affected module reduces, but also the temperature of the affected cells increases and causes irreversible damage to the affected cells in many cases . Bianchini et al. carried out an economic assessment of PV plants of different technologies.

Can phase change materials be used in photovoltaic (PV) modules for thermal regulation?

In recent years, the utilization of phase change materials (PCMs) in photovoltaic (PV) module for thermal regulation has attracted wide attention in this field, as the hybrid PV-PCM technology can not only achieve higher photoelectric conversion efficiency but also make it possible to extract thermal energy stored in PCMs for cascade utilization.
