“…4 The EVA is applied by a vacuum lamination process at $180 C, which results in a bubble-free layer that extends beyond the edges of the module and is mechanically trimmed. Some tests were also performed on BP Solar CdTe PV modules fabricated on tin-oxide-coated glass with a similar encapsulation process.…”

Electrochemical corrosion effects can occur in thin-film photovoltaic (PV) modules that are fabricated on tin-oxide-coated glass when operating at high voltages and at elevated temperatures in a humid climate. The current study shows that this corrosion is associated with a delamination of the tin oxide layer from the glass, which is caused by sodium accumulation near the interface between the tin oxide and the glass and by the ingression of moisture into the PV module from the edges. This corrosion in thin-film PV modules can be significantly reduced by altering the growth conditions of the tin oxide or by using zinc oxide as a transparent conductive oxide electrode.

“…The voltage characteristic equation of a cell obtained in generating mode is the same as one of a module, with one more parameter which indicates the number of cells in series ( Z ). So the equation of the module is as follows [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]: In average, each cell can provide a continuous nominal voltage of 0,6 volts, thus to obtain a voltage higher than 12 volts it is necessary to put several cells in series. Figure 2 shows the module voltage and power behaviour with 36 identical cells.…”

This paper proposes a control method for the maximum power point tracking (MPPT) of a photovoltaic system and this with the aim of increasing the output power of a photovoltaic system. An electronic controller is built-in between the photovoltaic generator and the load, whose principal role is the permanent monitoring of the maximum power point of the PV generator commonly called MPPT (Maximum Power Point Tracking) and that in general by acting on a DC-DC converter device. The contribution of this paper resides at the level DC converter device. The contribution of this paper resides at the level of the electric output of the converter, which can be estimated thru three state variables, which are the solar insolation, the temperature of the junction and information on the dynamics of the charging voltage if it exists.

“…Again, the device current is reduced at the expense of an increase of the driving voltage, with the sub-OLEDs determining the current flowing through the luminaire. Such monolithic connections are well established for thin-film photovoltaic modules and, for example, used with amorphous silicon, , copper indium gallium selenide − or organic semiconductors. − Recently, the concept has been transferred to OLEDs, where the connection can be established through patterning the luminaire in three subsequent steps, referred to as P1, P2, and P3 (Figure ). P1 patterning separates the bottom electrodes, forming an electrode array.…”

The plethora of design opportunities renders organic light emitting diodes (OLEDs) ideal luminaires for general lighting applications. Progressing from lab-scale device concepts to large-area applications calls for smart device designs that are scalable and, at the same time, unsusceptible to resistive losses within the electrodes. By employing direct pulsed femtosecond laser structuring, we fabricate OLED luminaires comprising monolithically interconnected OLED arrays. We determine the laser ablation thresholds and the optimized process parameters for all functional layers. The clean laser cuts with precise ablation depths show no detectable damage to adjacent layers or any ridges, hence avoiding unwanted short-cuts or device isolation. All processes are scalable. The 3-fold structuring of the OLED luminaire is confined within 45 μm and hence below the resolution limit of the human eye, yielding a geometric fill factor beyond 99% and therefore a very homogeneous device perception.
