Numerical Simulation for Optimization of Ultra-thin n-type AZO and TiO2 Based Textured p-type c-Si Heterojunction Solar Cells

Silicon Heterojunction Solar Cells on N- and P-type Wafers

A systematic comparison of frontand rear-emitter silicon heterojunction solar cells produced on nand p-type wafers was performed, in order to investigate their potential and limitations for high efficiencies. Cells on p-type wafers suffer from reduced minority carrier lifetime in the low-carrier-injection range, mainly due to the asymmetry in interface defect capture cross sections. This leads ...

a-Si/c-Si1-xGex/c-Si Heterojunction Solar Cells

The performance and material quality requirements of thin film a-Si/c-Si1-xGex/Si heterojunction solar cells are investigated by modeling and simulation. The effects of Ge content, Si1-xGex thickness, Si1-xGex lifetime and a-Si/c-Si1-xGex interfacial quality have been studied. The simulations predict that Si1-xGex based thin film solar cells provide a significant increase in solar cell output c...

Novel High-Efficiency Crystalline-Si-Based Compound Heterojunction Solar Cells: HCT (Heterojunction with Compound Thin-layer)

p-type Mesoscopic Nickel Oxide/Organometallic Perovskite Heterojunction Solar Cells

In this article, we present a new paradigm for organometallic hybrid perovskite solar cell using NiO inorganic metal oxide nanocrystalline as p-type electrode material and realized the first mesoscopic NiO/perovskite/[6,6]-phenyl C61-butyric acid methyl ester (PC61BM) heterojunction photovoltaic device. The photo-induced transient absorption spectroscopy results verified that the architecture i...

Understanding of Passivation Mechanism in Heterojunction c-Si Solar Cells

Intrinsic hydrogenated amorphous silicon (a-Si:H) films can yield in outstanding electronic surface passivation of crystalline silicon (c-Si) wafers as utilized in the HIT (heterojunction with intrinsic thin layer) solar cells. We have studied the correlation between the passivation quality and the interface nature between thin amorphous layers and an underlying c-Si substrate for understanding...
