TL;DR: In this paper, a comparative study comprising three transition metal oxides, MoO3, WO3 and V2O5, acting as front p-type contacts for n-type crystalline silicon heterojunction solar cells was performed.

TL;DR: In this paper, an improved equivalent circuit for hydrogenated amorphous silicon (a-Si:H) solar cells and modules is presented, based on the classic combination of a diode with an exponential current-voltage characteristic, of a photocurrent source plus a new term representing additional recombination losses in the i-layer of the device.

TL;DR: In this article, the authors demonstrate the applicability of the unified model and parameter extraction method (UMEM) to organic thin film transistors, OTFTs, which has been previously used with a-Si:H, polysilicon and nanocrystalline TFTs.

TL;DR: In this paper, the authors used polymethyl methacrylate as a gate dielectric to obtain pentacene thin-film transistors with field effect mobilities of 0.01 cm2 V−1 s−1 and low threshold voltages (−15 V.

TL;DR: In this article, the interface between n-type c-Si (n-Si) and three thermally evaporated transition metal oxides (TMOs) was investigated by transmission electron microscopy, secondary ion-mass, and x-ray photoelectron spectroscopy.
