ABSTRACTA calibration procedure for determining the model input parameters of standard a-Si:H layers, which comprise a single junction a-Si:H solar cell, is presented. The calibration procedure consists of: i) deposition of the separate layers, ii) measurement of the material properties, iii) fitting the model parameters to match the measured properties, iv) simulation of test devices and comparison with experimental results. The inverse modeling procedure was used to extract values of the most influential model parameters by fitting the simulated material properties to the measured ones. In case of doped layers the extracted values of the characteristic energies of exponentially decaying tail states are much higher than the values reported in literature. Using the extracted values of model parameters a good agreement between the measured and calculated characteristics of a reference solar cell was reached. The presented procedure could not solve directly an important issue concerning a value of the mobility gap in a-Si:H alloys.

Coal mine roadway deformation have a significant impact on coal mine production. Based on the Arduino microcontroller system and ultrasonic distance sensor, through temperature compensation and system fixes, designed a roadway deformation monitoring system which is high accuracy, low price and simple operation. Monitoring results through the LCD display, and SD card for data storage, the system achieved real-time monitoring of roadway deformation. The system was actually tested in coal mine, and achieved good monitoring results.
