Efficiency Improvement Using Molybdenum Disulphide Interlayers in Single-Wall Carbon Nanotube/Silicon Solar Cells

Efficiency Enhancement of Si Solar Cells by Using Nanostructured Single and Double Layer Anti-Reflective Coatings

The effect of single and double-layer anti-reflective coatings on efficiency enhancement of silicon solar cells was investigated. The reflectance of different anti-reflection structures were calculated using the transfer matrix method and then to predict the performance of solar cells coated by these structures, the weighted average reflectance curves were used as an input of a PC1D simulation....

Efficiency improvement of crystalline silicon solar cells

To increase the efficiency and reduce the production cost of crystalline silicon (c-Si) solar cells, efforts in the photovoltaic industry are currently put on the process optimization of the cell. Sodium hydroxide/Potassium hydroxide (NaOH/KOH) and isopropyl alcohol (IPA) are widely used in the standard alkaline texturization of mono crystalline silicon (mc-Si) wafers for enhancing the optical ...

Increasing organic solar cell efficiency with polymer interlayers.

We demonstrate how organic solar cell efficiency can be increased by introducing a pure polymer interlayer between the PEDOT:PSS layer and the polymer:fullerene blend. We observe an increase in device efficiency with three different material systems over a number of devices. Using both electrical characterization and numerical modeling we show that the increase in efficiency is caused by optica...

Air-Stable High-Efficiency Solar Cells Using Improved Single-Walled Carbon Nanotube Films

Enhanced solar energy conversion in Au-doped, single-wall carbon nanotube-Si heterojunction cells

The power conversion efficiency (PCE) of single-wall carbon nanotube (SCNT)/n-type crystalline silicon heterojunction photovoltaic devices is significantly improved by Au doping. It is found that the overall PCE was significantly increased to threefold. The efficiency enhancement of photovoltaic devices is mainly the improved electrical conductivity of SCNT by increasing the carrier concentrati...
