4. Influence of heavy doping effects on performance of the front region The front regions of silicon solar cells, whether obtained by diffusion or by ion implantation with subsequent activation annealing, contain a large impurity gradient between the edge of the space charge region of the pfn junction and the front surface.
To optimize the performance of both solar cells as well as LEDs via doping, it is important to have knowledge of the capture coefficients of the defect level to make an informed choice on the type as well as amount of doping that will ensure the reduction in the share of nonradiative recombination.
Methodology There are generally two regions in solar cells of conventional design in which heavy doping effects are encountered. One of these is the BSF structure, which in its original version involved a relatively thin diffused or ion implanted layer with a drift field just below the contact-covered back surface of the cell.
Inside a real device, whether doping will improve photovoltaic performance will depend on the interplay of the two effects of doping listed above. Besides, other factors like mobility of the transport layer, the asymmetric coefficients of recombination will also influence the impact of doping on photovoltaic performance.
It is found that the doping density of the electron transport layer (TiO 2) and absorber layer (CsSnI 3) has a significant effect on the band alignment and thus on the device performance; however, an increase in the acceptor doping density of the hole transport layer (CuSCN) does not make any significant changes in the device performance.
The photovoltaic performance may improve at an optimum doping density which depends on a range of factors such as the mobilities of the different layers and the ratio of the charge carrier capture cross sections.
