Abstract
The performance of a novel hydrogenated amorphous silicon (a-Si : H) solar cell which utilizes the field effect solar cell (FESC) has been investigated both theoretically and experimentally. The theoretical analysis has been done for bothp- andn-channel FESCs by employing a two-dimensional device simulator which is based on current continuity and Poisson equations. The calculated performance is compared with that of conventional (p-i-n)a-Si : H solar cells. The calculation demonstrated that bothn-channel andp-channel FESCs could improve the conversion efficiency by as much as 50%.
In order to check the reliability of simulation, the transport properties of intrinsica-Si : H film and thin film transistor (TFT) have also been calculated and compared with the experimentally obtained characteristics. Experimental verification of TFT and FESC has been attempted by using MgO anda-SiN : H as dielectric layer materials. Preliminary results are presented.
