| Popis: | 106 In this work, Heterojunction Intrinsic Thin-layer (HIT) solar cell is incorporated with the luminescent down-shifting (LDS) mechanism for the incident spectrum. LDS layers contain the conversion from underutilized high-energy photon to lower energy photon where the spectral response of the solar cell is more efficient. The method conquers the poor response and surface recombination effect of solar cell at short wavelength. The HIT solar cell is highly efficient, low temperature < 260°C, low cost, and highly symmetrical device. A thin phosphor layer is spray coated on the top of HIT solar cell for the luminescent down-shifting of high energy photons and thus enhanced absorbance for the device around =600nm is reported where the external quantum efficiency (EQE) is the highest for amorphous silicon solar cells. As a result, the Jsc increased 11~17%, then increasing the η 14~16%. Finally, phosphor can apply in any kind of solar cells with increasing Jsc and η. This study shows the phosphors’ potential for becoming next generation solar cell in the future. |
