PV-assisted heat pump prototype with dual condenser reaches 7.59 coefficient of performance
Researchers in Spain have developed a dual-condenser air-to-water heat pump that shifts domestic hot water production to daylight hours, maximizing PV self-consumption. The prototype boosted solar energy use from 9.9% to 55.5% and achieved a peak coefficient of performance of 7.59 under PV-assisted operation.
Indian researchers build transparent perovskite-silicon tandem solar cell with 30.2% efficiency
The transparent four-terminal perovskite solar cell employs an ion-modulated spiro-MeOTAD hole transport layer, which passivates interfacial defects, enhances carrier dynamics, and allows for a tunable work function in wide-bandgap perovskites. When integrated into mechanically stacked 4T tandems with an n-TOPCon cell, the device achieved an overall efficiency of 28.4–30.2%, along with improved open-circuit voltage and fill factor.
Premier Energies unveils India’s first zero-busbar TOPCon solar cell
Premier Energies Ltd today unveiled India’s first zero-busbar (0BB) TOPCon solar cell at Intersolar India. The 0BB design marks a structural shift from traditional 10BB and 16BB architectures, replacing thick silver busbars with a dense matrix of ultra-fine silver lines to collect current.
