Bulk heterojunction solar cell devices comprising these polymers were prepared by solution processing blends of each polymer with [6,6]-phenyl-C61-butyric [6,6]-phenyl-C61-butyric [6,6]-phenyl-C61-butyric [6,6]-phenyl-C61-butyricconversion efficiencies.
Measured power gain and conversion efficiency of the solid state RF power amplifier module at 1.06 kW output is 21.7 dB and 73.2%, respectively.
The proposed RF energy harvester exhibits a measured maximum power conversion efficiency (PCE) of 32% at −15 dBm (32 μW) and delivers an output DC voltage of 3.2 V to a 1 MΩ load.
In the best case, the proposed rectifier exhibits the measured maximum power conversion efficiency of 74% at the input RF level of 2 dBm for the resistive load of 5 kΩ.
Its performances as sensitizers in solar cells were measured, and possessed a power conversion efficiency of 4.80%.
The performance of the circuits was measured in terms of the power conversion efficiency (PCE), and this characterization was done for RF input power ranging from 20 dBm to 0 dBm.
The measured results show that the power conversion efficiency performance at lower input RF power level has been improved in the proposed circuit as compared to the traditional VM circuit.
At the same time, electrical analysis was performed on devices; power conversion efficiency (PCE), measured before and after the encapsulation process, showed that sealing at temperatures higher than 100 °C strongly damages the electrical parameters.
