TL;DR: A number of solid state organic solar cells have been prepared and tested in simulated sunlight as mentioned in this paper, and the most efficient device consisted of a sandwich of thin layers of indium-tin oxide/malachite green/a benzothiazole-rhodanine merocyanine/Au on Pyrex.
Abstract: A number of solid state organic solar cells have been prepared and tested in simulated sunlight. Photovoltaic effects were consistent with the formation of a rectifying junction at the interface between a triphenylmethane dye (n-type) and a merocyanine dye (p-type). The most efficient device consisted of a sandwich of thin layers of indium-tin oxide/malachite green/a benzothiazole-rhodanine merocyanine/Au on Pyrex. Exposure of the cell to chlorine vapour in the absence of air improved the sunlight efficiency to 0.12%. Investigations of the photocurrent action spectrum, rectification and capacitance have given mechanistic information on the photovoltaic energy conversion processes.

TL;DR: In this article, a solar cell is covered with solderable metals, including tin, silver, copper, and nickel, with aluminum, and the contacts are formed by spraying the metals onto the cell surfaces, together or as layers, with an aluminum-containing layer in direct contact with cell surfaces.
Abstract: Electrically conductive contacts containing solderable metals, including tin, silver, copper and nickel, with aluminum are formed on the front and/or back surfaces of a solar cell. They are deposited by spraying the metals onto the cell surfaces, together or as layers, with an aluminum-containing layer in direct contact with the cell surfaces.

TL;DR: In this article, the photovoltaic effect was observed in several types of device structure such as p/n, p/i/n and Schottky barrier junctions as well as heterojunctions.
Abstract: In 1969, Chittick et al.(1) reported preliminary results on hydrogenated amorphous Si (a-Si:H) and substitutional doping of a-Si:H by P. In 1976, the first p/n junction in a-Si:H was reported by Spear et al.(2) following a detailed and extensive study(3) of substitutionally doped a-Si:H films. This was followed by the fabrication of a-Si:H photovoltaic cells at RCA laboratories.(4,5) The photovoltaic effect was observed in several types of device structure such as p/n, p/i/n, and Schottky barrier junctions as well as heterojunctions.

TL;DR: In this article, the integrated type multi-bandgap a-Si solar cell was proposed, in which stacked type solar cells having different bandgaps are integrated on one substrate, and an optimum design theory was established.
Abstract: A new type of solar cell, called the “integrated type multi-bandgap a-Si solar cell”, in which stacked type solar cells having different bandgaps are integrated on one substrate, was proposed. Materials, design theory and a processing method were investigated. As a narrow bandgap material, a-SiSn:H was first deposited from a glow discharge reaction, and the photovoltaic effect of a-SiSn:H was observed. As a wide bandgap material, a-SiN:B:H deposited from a glow discharge was found to have good properties for use in solar cells. An optimum design theory for this type of a-Si solar cell was established, and it was found to be useful for the fabrication of the integrated structure.

TL;DR: In this article, the authors describe correlations between deposition parameters and photovoltaic properties of intrinsic amorphous silicon films produced by RF sputtering and present data showing a strong dependence between photovelectric properties and structural and compositional inhomogeneity of the films.
Abstract: This paper describes correlations between deposition parameters and photovoltaic properties of intrinsic amorphous silicon films produced by RF sputtering. We present data showing strong dependence between photovoltaic properties and structural and compositional inhomogeneity of the films. Studies on films produced at different hydrogen concentrations show that the ones with larger optical gaps have better photovoltaic potential. Small concentration of dopant impurities in the intrinsic films has significant effect on their photovoltaic properties. These optimization studies lead to intrinsic material, which when incorporated in a P-I-N solar cell generates external currents up to 13 mA/cm2 and open circuit voltages of between 0.85 to 0.95 volts.© (1983) COPYRIGHT SPIE--The International Society for Optical Engineering.
