Scientists identify new ‘promising’ absorber material for thin-film solar cells

Researchers in the United States have identified zintl-phosphide (BaCd2P2) as a new potential high efficiency absorber material for thin-film PV applications among 40,000 promising inorganic materials. The selected compound has a potential energy bandgap of 1.45 eV and a carrier lifetime of up to 30 ns.

U.S. scientists build hybrid energy system integrating PV, radiative cooling

The hybrid system has a cooling power of 63.8 W/m2 and a photovoltaic power output of 159.9 W/m2. According to its creators, the cooling capacity provided by the system can be used in buildings or refrigerators.

Tandem solar cell based on cadmium telluride, iron disilicide promises 43.9% efficiency

Researchers in Bangladesh have designed a dual-junction tandem solar cell with a bottom device based on iron disilicide (FeSi2), an emerging absorber material know for its high thermal stability and good optoelectronic properties. Their simulation showed the advantage of combining the larger bandgap of the top cadmium telluride cell and the smaller bandgap of the bottom FeSi2 cell.
