A p-type transparent conductive oxide and a solar cell containing the p-type transparent conducting oxide, wherein the p-type transparent conductive oxide includes a molybdenum trioxide doped with an element having less than six valence electrons, the element is selected from the group consisting of alkali metals, alkaline earth metals, group III elements, group IV, group V, transition elements and their combinations. Doping an element having less than six valence electron results in hole number increase, and thus increasing the hole drift velocity, and making Fermi level closer to the range of p-type materials. Hence, a p-type transparent conductive material is generated. This p-type transparent conducting oxide not only has high electron hole drift velocity, low resistivity, but also reaches a transmittance of 88% in the visible wavelength range, and therefore it is very suitable to be used in solar cells.

P-type transparent conductive oxide for solar cell comprising molybdenum trioxide doped with indium

A specimen kit for enclosing a specimen is described, including a first substrate, a second substrate and a sealant. The first substrate has a first observation window at which a thickness thereof is smaller than that of the other parts thereof. The second substrate has a second observation window at which a thickness thereof is smaller than that of the other parts thereof, and is disposed on the first substrate such that the second observation window is aligned to the first observation window and an interval is present between the first and the second substrates. The sealant is disposed between the first and the second substrates and surrounds the first and the second observation windows to seal a space between fringes of the first and the second substrate, thus defining a specimen cell between the first and the second substrates.
