Perovskite solar cells with high-efficiency exceeding 25%: A
Metal halide perovskite solar cells (PSCs) are one of the most promising photovoltaic devices. Over time, many strategies have been adopted to improve PSC efficiency, and the certified efficiency has reached 26.1%. However, only a few research groups have fabricated PSCs with an efficiency of >25%, indicating that achieving this efficiency remains uncommon.

Solar Performance and Efficiency
The conversion efficiency of a photovoltaic (PV) cell, or solar cell, is the percentage of the solar energy shining on a PV device that is converted into usable electricity. Improving this conversion efficiency is a key goal of research and helps make PV technologies cost-competitive with conventional sources of energy.

Photovoltaic Cell Efficiency
When temperature increases, the reverse saturation current of the solar cell increases and thereby reduces the open circuit voltage of the cell. This reduces the fill factor and the efficiency of the solar cell [115,116]. To some extent, this efficiency reduction can be lowered by trimming the reflection of the incident solar light.

What is the power conversion efficiency of a solar cell?
The power conversion efficiency of a solar cell is a parameter that quantifies the proportion of incident power converted into electricity. The Shockley-Queisser (SQ) model sets an upper limit on the conversion efficiency for a single-gap cell.
What is the maximum room-temperature power conversion efficiency of a solar cell?
The maximum possible room-temperature power conversion efficiency of a single junction, c – Si solar cell under 1–sun illumination, according to the laws of thermodynamics, is 32.33% 6. This limit is based on the assumptions of perfect solar absorption and no losses due to non-radiative charge-carrier recombination.
How efficient is a solar cell at 36°C?
Literature indicates that at a cell temperature of 36°C, efficiency somewhat increases by up to 12%. However, efficiency starts to decrease above this temperature, as Fig. 13 a illustrates. There are many efficient methods for controlling the operating temperature of solar cells which include both active and passive approaches.
How efficient are solar cells?
Solar cells of this kind, characterized by reduced material usage, lower manufacturing costs, and flexibility, typically achieve conversion efficiencies ranging from 6% to 15% (Jaiswal et al., 2022).
What is the limiting efficiency of a silicon solar cell?
The best real-world silicon solar cell to date, developed by Kaneka Corporation, is able to achieve 26.7% conversion efficiency 7, 8. A loss analysis of this 165 μm -thick, heterojunction IBC cell shows that in absence of any extrinsic loss mechanism the limiting efficiency of such a cell would be 29.1% 7.
How efficient are silicon solar cells in the photovoltaic sector?
The photovoltaic sector is now led by silicon solar cells because of their well-established technology and relatively high efficiency. Currently, industrially made silicon solar modules have an efficiency between 16% and 22% (Anon (2023b)).
