How efficient is a c-Si solar cell?

Nat. Energy 2, 17032 (2017). This study presents an efficient (PCE = 26.6%) c-Si solar cell with the IBC–SHJ architecture. Green, M. A. et al. Solar cell efficiency tables (version 52). Prog. Photovolt. 26, 427–436 (2018). Taguchi, M. et al. 24.7% record efficiency HIT solar cell on thin silicon wafer. IEEE J. Photovolt. 4, 96–99 (2014).

Can crystalline silicon solar cells have junctions without diffused emitters?

Device designs that avoid diffused emitter regions and direct metal-absorber contacts, commonly denoted as passivated contacts, are key enablers for a further increase of efficiency. So far, three concepts have been developed that enable junction formation in crystalline silicon solar cells without diffused emitters.

Are passivating contacts a viable solution for silicon solar cells?

Passivating contacts hold promise for silicon solar cells yet the simultaneous optimization of conductivity, defect passivation and optical transparency remains challenging. Now Köhler et al. devise a passivating contact based on a double layer of nanocrystalline silicon carbide that overcomes these trade-offs.

What is perovskite barium stannate?

Among the transparent conducting oxides, the perovskite barium stannate is most promising for various electronic applications due to its outstanding carrier mobility achieved at room temperature. However, most of its important characteristics, such as band gaps, effective masses, and absorption edge, remain controversial.

Do lanthanide based PSCs affect voltaic device performance & stability?

The shifting of energy levels of CTL impacts the Voc of the photovoltaic devices. By summarizing data from all reported work of lanthanide and nonlanthanide-based PSCs, it is clear that DC materials show huge impact on device performance and stability.
