Abstract:
Provided is a photovoltaic (PV) module by which electric power generation efficiency can be improved by improving light use rate. An encapsulant (202) is permitted to be a first layer (A cover glass (201) and the encapsulant (202) are considered optically equivalent, since their refractive indexes are substantially the same), a light trapping film (300) to be a second layer, an anti-reflective layer (104) to be a third layer, and an n-type layer (103) to be a fourth layer. When the reflective indexes of the layers are expressed as first reflective index (n1), second reflective index (n2), third reflective index (n3) and fourth reflective index (n4), relationship n1≦n2≦n3≦n4 is satisfied. The light trapping film (300) of the second layer, i.e., one layer among the light transmitting layers, has a structured shape on an incident side (300a) where incident light (205) enters.

Abstract:
Provided is a production process by which a novel alicyclic oxetane compound which has an oxetane ring, has excellent light transmission in the near ultraviolet region, and is useful as a cationically polymerizable monomer can be easily obtained. The production process which is for obtaining an alicyclic oxetane compound includes subjecting an aromatic oxetane compound to nuclear hydrogenation in high-pressure hydrogen in the presence of a hydrogenation catalyst. For example, when 4,4′-bis[(3-ethyloxetan-3-yl)methoxymethyl]biphenyl is used as the aromatic oxetane compound, 4,4′-bis[(3-ethyloxetan-3-yl)methoxymethyl]bicyclohexyl is obtained as the alicyclic oxetane compound.
