Meanwhile, the thickness of the P3HT layer was optimized for the fabrication of Gr–GaAs solar cells. A PCE of 13.7% has been achieved for the solar cell with a P3HT layer, which is the new record for the efficiency of Gr–GaAs solar cells. These results pave a new way for the fabrication of high efficiency Gr–GaAs solar cells.
We have investigated the performance of Schottky junction solar cells based on silicon and graphene with 1–6 layers.

1. Introduction. Due to the attractive characteristics of graphene, it has been used to prepare graphene devices such as solar cells [1].Several structures have been developed to develop graphene/n-silicon (Si) Schottky junction solar cells [2], [3], [4].One of those structures is the top-window structure [2], which has been widely reported for the fabrication process.
This paper investigated the effect of PbS quantum dots on the efficiency of the amorphous silicon thin-film Schottky solar cell.

Schottky junction solar cells A photovoltaic cell can be created from the Schottky junction between a semiconductor and a metal, with or without an insulating layer between them. Solar cells of this type have a long history, dating back to 1883, when Charles Fritts coated selenium with a thin layer of gold to make one of the world''s first solar cells. However, since then, they …
Graphene/silicon (Gr/Si) Schottky junction solar cells have attracted extensive research interest due to their simple structure and potential low-cost.
The Gr/Si solar cells can be fabricated by simply transferring a graphene film onto a n-Si substrate at room temperature, and thus they have merits of low-cost and ease of fabrication compared to the traditional Si solar cells based on p-n junction. Since the first Gr/Si solar cell achieved a power conversion efficiency (PCE) of 1.5% [1], many ...
In this work, we demonstrate the fabrication of highly-efficient GaAs/graphene Schottky junction solar cells by modifying the interface of the device with a self-assembled alkyl thiol monolayer (SAM).
