Typed bounds on this route
Every limit the atlas holds for this route, as constraint records: reached through bounded_by claims on the route's own entities. Hard bounds (an upper bound or a formula) decide the thermodynamic-bound check above; benchmarks, constitutive relations and resource limits are listed and never decisive. No prose limit exists anywhere (pass 42).
- Shockley–Queisser limit · upper-bound · hard, applies to this routeη ≤ 33.7% for a single p–n junction under unconcentrated AM1.5 sunlight
- Landsberg limit · formula-bound · hard, applies to this routeη ≤ 1 − (4/3)(T_c/T_s) + (1/3)(T_c/T_s)⁴ for conversion of blackbody radiation at T_s with a sink at T_c; 93.3 % at 6000 K / 300 K
