Tervo et al. propose a solid-state heat engine for solar-thermal conversion: a solar thermoradiative-photovoltaic system. The thermoradiative cell is heated and generates electricity as it emits light to the photovoltaic cell. Combining these two devices enables efficient operation at low temperatures, with low band-gap materials, and at low optical concentrations.

Solar-cell efficiency is the portion of energy in the form of sunlight that can be converted via photovoltaics into electricity by the solar cell. The efficiency of the solar cells used in a photovoltaic system, in combination with latitude and climate, determines the annual energy output of the system.
We measured a solar-to-electrical conversion rate of 6.8%, exceeding the performance of the photovoltaic cell alone. The device operates more efficiently while reducing the heat generation rates

NREL has updated its Best Research-Cell Efficiency Chart. The tool highlights the highest confirmed conversion efficiencies of research cells for a range of PV technologies.
Factors Affecting Conversion Efficiency . Not all of the sunlight that reaches a PV cell is converted into electricity. In fact, most of it is lost. Multiple factors in solar cell design play roles in limiting a cell''s ability to convert the sunlight it receives. Designing with these factors in mind is how higher efficiencies can be achieved.
The efficiency is the most commonly used parameter to compare the performance of one solar cell to another. Efficiency is defined as the ratio of energy output from the solar cell to input energy from the sun. In addition to reflecting the performance of the solar cell itself, the efficiency depends on the spectrum and intensity of the incident

It depends on the material of the cell. In the case of Silicon, exposed to solar radiation (without concentrating it), 22% of the energy of the AM 1.5 spectrum does not have enough energy to create the pair eh; another 32% is lost because the photons have more energy than 1.11 eV. Therefore, only 49.6% of the energy (efficiency) could be converted.
Solar panel efficiency refers to how much of the sun’s energy striking the panel is converted into usable electricity. The more efficient the solar panels are, the more power they will produce. Understanding the key factors that affect solar panel efficiency can help you make informed decisions when shopping for a solar photovoltaic (PV) system.
“The format of the chart will soon change to include hybrid tandems.” The chart now includes the 33.9% world record efficiency achieved in November by Chinese manufacturer Longi for a perovskite-silicon tandem solar cell and the 27.09% efficiency achieved by the same company for a heterojunction back contact solar cell.
Solar cell efficiencies vary from 6% for amorphous silicon-based solar cells to 44.0% with multiple-junction production cells and 44.4% with multiple dies assembled into a hybrid package. Solar cell energy conversion efficiencies for commercially available multicrystalline Si solar cells are around 14–19%.
