Solar energy is reaching new heights faster than ever.
A tandem solar cell developed by researchers at the Helmholtz Zentrum Berlin (HZB) has converted 32.5 percent of incident solar radiation into electrical energy, a world record. The achievement was certified by the European Solar Test Installation (ESTI) in Italy, a university press release said.
As the demand for renewable energy grows, researchers are looking at ways of increasing the efficiency of solar cells. This enables more energy to be harvested from the same area of land deployed to generate power. There has been significant success when halide perovskites have been used to make solar cells.
