对氢化非晶硅太阳电池的开路电压进行了实验研究和计算机模拟。我们发现，带隙和缺陷状态影响Voc显着。氢（H2）稀释加宽了带隙并降低了缺陷态密度;这两者都有助于在H2稀释的太阳能电池中获得更大的Voc和更好的填充因子。价带尾变窄可能会影响Voc，但由于缺乏可用的数据，本文没有将其包括在内。本文通过实验和计算机模拟研究了氢化非晶硅太阳电池的开路电压（Voc）。我们发现，带隙和缺陷状态影响Voc显着。氢（H2）稀释加宽了带隙并降低了缺陷态密度;这两者都有助于在H2稀释的太阳能电池中获得更大的Voc和更好的填充因子。价带尾部变窄可能影响Voc，但由于缺乏可用数据，未纳入本研究。
The open-circuit voltage (Voc) of hydrogenated amorphous silicon solar cells has been studied experimentally and by computer simulation. We find that band gap and defect states affect Voc significantly. Hydrogen (H2) dilution widens the band gap and reduces density of defect states; both contribute to larger Voc and better fill factor in H2 diluted solar cells. Valence band tail narrowing could affect Voc, but is not included in this study due to lack of available data.The open-circuit voltage (Voc) of hydrogenated amorphous silicon solar cells has been studied experimentally and by computer simulation.
