We will show the current-voltage behaviors and band diagrams of HIT cells with and without hole thermionic emission model. When the hole thermionic emission model is not included, only drift diffusion model is used. In such a case, the calculated current would be much larger than the practical value.
The effect of low irradiance for thin film solar cells is investigated in this work. First, a-Si:H/CIGS/DSSC/OPV four kinds of thin film solar cells are fabricated and measured with the sun simulator (AM 1.5G, 100 mW/cm2). Then, the saturation current density J0 is extracted from the Voc and Jsc. Spectral irradiance of the desk light, LED light, sun light at the windowsill and fluorescent lamp are...
A texturization method suitable for both c- and mc-Si is developed. The method is applied on as-cut wafers and is found to be suitable for combined saw damage removal and texture formation. The texturization with inverted surface structures was obtained using wet chemistry process sequence at room temperatures without using a mask and lithography. Potential for an improvement of the standard screen...
