在这项研究中，我们展示了在同向外延生长的p掺杂Rubrene单晶衬底上制作的施主/受主光伏电池的工作原理。光电流密度主要受掺杂到100ppm的p型单晶层的电导率(σ-)所控制。需要65μm厚的p型Rubrene单晶衬底，光电流密度为20 mA·cm−2。为了制造实用的有机单晶太阳能电池，Rubrene单晶的整体掺杂技术是必不可少的。
In this study, the operation of donor/acceptor photovoltaic cells fabricated on homoepitaxially grown p-doped rubrene single-crystal substrates is demonstrated. The photocurrent density is dominated by the sheet conductivity (σ□) of the p-type single-crystal layer doped to 100 ppm with an iron chloride (Fe2Cl6) acceptor. A 65 μm thick p-type rubrene single-crystal substrate is expected to be required for a photocurrent density of 20 mA·cm−2. An entire bulk doping technique for rubrene single crystals is indispensable for the fabrication of practical organic single-crystal solar cells.
