What is the temperature dependence of a polycrystalline silicon solar cell?

The temperature dependence of individual efficiencies (Absorption efficiency, Thermalization efficiency, Thermodynamic efficiency and Fill factor) and overall conversion efficiency of a polycrystalline silicon solar cell has been investigated in temperature range 10–50 °C. The all efficiencies present a decrease versus temperature increase.

How efficient are solar cells?

Photovoltaic (PV) conversion of solar energy starts to give an appreciable contribution to power generation in many countries, with more than 90% of the global PV market relying on solar cells based on crystalline silicon (c-Si). The current efficiency record of c-Si solar cells is 26.7%, against an intrinsic limit of ~29%.

What is a silicon photovoltaic (PV) solar cell?

Introduction The silicon photovoltaic (PV) solar cell is one of the technologies are dominating the PV market. The mono-Si solar cell is the most efficient of the solar cells into the silicon range. The efficiency of the single-junction terrestrial crystalline silicon PV cell is around 26% today (Green et al., 2019, Green et al., 2020).
