Imec Beats Silicon PV with 27.1 Percent Perovskite-Silicon Tandem

Imec, the world-leading research study and development center in nanoelectronics, energy and digital technology, within the collaboration of EnergyVille, today revealed a record outcome for its 4-terminal Perovskite/ silicon tandem photovoltaiccell With a power conversion effectiveness of 27.1 percent, the brand-new imec tandem cell beats the most effective standalone silicon solarcell Further mindful engineering of the Perovskite product will bring performances over 30% in reach.

Perovskite microcrystals are an appealing product system to make high-performance thin-film solar batteries. They can be processed into thin, light, semitransparent modules that can accomplish a high power conversion effectiveness, are economical to produce, and have a high absorption effectiveness for sunshine. Because they can be made semitransparent, perovskite solar batteries and modules can likewise be utilized on top of silicon solar batteries. When the Perovskite is thoroughly crafted, the absorbance in the Perovskite reduces the thermal losses that happen in the siliconcell As an outcome, a Perovskite- silicon tandem solar cell can possibly reach power conversion performances above 30 percent.

Imec’s brand-new record tandem cell utilizes a 0.13 cm ² spin-coated Perovskite cell established within our Solliance cooperation stacked on top of a 4 cm ² commercial interdigitated back-contact (IBC) silicon cell in a 4-terminal setup, which is understood to have a greater yearly energy yield compared with a 2-terminal setup. Additionally, scaling up the tandem gadget by utilizing a 4 cm2perovskite module on a 4 cm2IBC silicon cell, a tandem effectiveness of 25.3% was attained, going beyond the stand-alone effectiveness of the silicon cell.

ManojJaysankar, doctoral scientist at imec/EnergyVille, includes: “We have been working on this tandem technology for two years now, and the biggest difference with previous versions is in the engineering and processing of the Perovskite absorber, tuning its bandgap to optimize the efficiency for tandem configuration with silicon.”

“Adding Perovskite on top of industrial silicon PV may prove to be the most cost-effective approach to further improve the efficiency of photovoltaics,” concludes Tom Aernouts, group leader for thin-film photovoltaics at imec/EnergyVille. “Therefore, we invite all companies in the PV value chain that are looking into higher efficiencies, to partner with us and explore this promising path.”
