A novel concept for photovoltaics that exploits the ability of materials to exist in different crystalline phases
The group of Prof. Yana Vaynzof at the Integrated Center for Physics and Photonic Materials (IAPP) and the Center for Advancing Electronics Dresden (cfaed) at Technische Universität Dresden has demonstrated a novel concept for solar cells that exploits the ability of materials to exist in different crystalline phases. The related study has now been published in the journal Nature Energy.
The purpose of a photovoltaic cell is to convert sunlight into electricity. By absorbing the sunlight, pairs of charge carriers are generated and then need to be guided to the opposite sides of the photovoltaic diode to produce electrical current. To facilitate this process, most solar cells include a heterojunction that provides a favorable energetic landscape to drive the charges to be separated.
For example, silicon solar cells form a heterojunction by electrically doping each side of the device, forming a p-n junction. Organic solar cells, on the other hand, rely on blending different types of materials (donor and acceptor) to form a bulk heterojunction. However, these concepts are often not applicable to emerging classes of novel photovoltaic materials.

(time for absurd questions)
if your tav/durge was transformed into a sheep with a polymorph spell, what would they really look like?
oh no something went wrong… Marrow and Diamant don't look harmless gods save us all
hungry durge sheep 👹 (or goblin goats??)

how better to describe my love for the Mighty Nein than "one of my favorite episodes was the one where they needed to stealthily climb up/get down a fucking huge tree only for it to get Very Loud And Chaotic Very Fast Due To Competitive Tendencies And Poor Decisions".
Except that describes TWO completely separate episodes (and trees), one involving romantic shenanigans, a baby roc getting hit on the head with a staff, and a shitty leaf costume, and the other involving a good ole footrace and also a bullet to the ass. No, no enemies had a gun.

A FINE LAD I FOUND DURING A BREAK AT D&D TONIGHT
Rolled a comfortable 18 on your random encounter table, did you? Congratulations.

the clip in Polymorph of Rimmer's brothers smearing his face with jam and releasing a tin of ants all over him gains an even more sad and sinister note when you remember that in Better Than Life one of the horrible things his brain manifested for himself and Lister and Cat was being buried alive up to their necks with their faces smeared with jam and having ants set loose on them

quick note: having multiple forms is complex. it can be liberating. it can also be frustrating, maddening even. you just want to be "you" and that is always changing. sometimes the different pieces seem to directly oppose each other and it makes you crazy. i don't have any answers here. no advice. just tell yourself "i don't know everything about myself yet, and that's okay."
that's all i've got.
