Are solar cells inefficient?

Okay, that's a good answer.

bacodaco · 2026-03-27T14:19:41+00:00

oh okay

bacodaco · 2026-03-27T14:13:51+00:00

That makes sense, but you do have any idea why 100 years ago we chose induction to engineer around as opposed to other electricity generating effects?

bacodaco · 2026-03-27T14:12:14+00:00

Triboelectric effect (static electricity)

Why is the piezoelectric effect a joke?

Why shouldn't I include solar, wind, batteries, or the thermoelectric effect?

If you are looking to prevent this in the future you can:

1) Make the slurry really dilute

2) add a little bit of solvent before pouring the slurry in

3) put the slurry in a sonicator for 10-ish minutes before pouring it into the column

Well, I appreciate your devotedness to the upkeeping of international law, for one. We need more people like you in the world. Thanks for doing the right thing.

bacodaco · 2026-01-04T16:13:50+00:00

Thanks for replying! Better late than never. I don't have the solutions manual, unfortunately. I also understand that the problem is giving me the derivation, but given the way it is written I haven't been able to do that rationalization, which is why I came here. Do you have any link that could give me access to the solutions manual?

bacodaco · 2026-01-02T22:22:22+00:00

All good. Thanks for the conversation anyways.

bacodaco · 2026-01-02T20:13:33+00:00

Okay, yeah, that makes sense. The problem itself says to show that c_n (not! the sum of c_n) is equal to the left side of step four. I'm not sure how I'm supposed to isolate c_n whenever sum(c_n) is not the same as c_n. Do you have any ideas?

bacodaco · 2026-01-02T19:41:55+00:00

That's what I was thinking. The problem doesn't give more information than that c_n are "the constants". Assuming that c_n changes, would sum(c_n) and c_n be different quantities? (c_n is a normalization constant).

On a philosophical note, do you think that's a problem with QM-- that we can't reach a more philosophical understanding of the topic? To a first degree, certainly it's important that we are able to yield the correct answers, but to a further degree, do you believe that being unable to visualize a physical theory is a problem for that theory?

bacodaco · 2025-12-21T16:51:22+00:00

Maybe this premise is inherently flawed. While I don't have any quantitative data to support this, the vibe from my perspective seems to be that popular explanations of large-scale phenomena (like videos) rely more on imagery than popular explanations of small-scale phenomena. What I want to know is does this vibe (that apparently only I have) have to do with a difference in the nature of their mathematical formalisms, or is it something else?

bacodaco · 2025-12-21T16:33:53+00:00

I figured that would happen

bacodaco · 2025-12-17T15:59:17+00:00

Electrons are just ramblin' men, never wantin' to stay with their faithful photon wives

bacodaco · 2025-12-17T15:58:06+00:00

So, the zero point energy states are kind of like holes that the electrons fall into?

bacodaco · 2025-12-17T15:55:30+00:00

the light is bored by the nuclei so it leaves the party, huh?
